Hugging Face was founded in 2016 by French entrepreneurs Clément Delangue, Julien Chaumond, and Thomas Wolf originally as a company that developed a chatbot app targeted at teenagers.[2] After open-sourcing the model behind the chatbot, the company pivoted to focus on being a platform for machine learning.
In March 2021, Hugging Face raised $40 million in a Series B funding round.[3]
On April 28, 2021, the company launched the BigScience Research Workshop in collaboration with several other research groups to release an open large language model.[4] In 2022, the workshop concluded with the announcement of BLOOM, a multilingual large language model with 176 billion parameters.[5]

Utility that performs several consistency checks on the repo. This includes:
- checking all models are properly defined in the __init__ of models/
- checking all models are in the main __init__
- checking all models are properly tested
- checking all object in the main __init__ are documented
- checking all models are in at least one auto class
- checking all the auto mapping are properly defined (no typos, importable)
- checking the list of deprecated models is up to date
Use from the root of the repo with (as used in `make repo-consistency`):
```bash
python utils/check_repo.py

# PPO Trainer
TRL supports the [PPO](https://arxiv.org/abs/1707.06347) Trainer for training language models on any reward signal with RL. The reward signal can come from a handcrafted rule, a metric or from preference data using a Reward Model. For a full example have a look at [`examples/notebooks/gpt2-sentiment.ipynb`](https://github.com/lvwerra/trl/blob/main/examples/notebooks/gpt2-sentiment.ipynb). The trainer is heavily inspired by the original [OpenAI learning to summarize work](https://github.com/openai/summarize-from-feedback).
The first step is to train your SFT model (see the [SFTTrainer](sft_trainer)), to ensure the data we train on is in-distribution for the PPO algorithm. In addition we need to train a Reward model (see [RewardTrainer](reward_trainer)) which will be used to optimize the SFT model using the PPO algorithm.
## Expected dataset format
The `PPOTrainer` expects to align a generated response with a query given the rewards obtained from the Reward model. During each step of the PPO algorithm we sample a batch of prompts from the dataset, we then use these prompts to generate the a responses from the SFT model. Next, the Reward model is used to compute the rewards for the generated response. Finally, these rewards are used to optimize the SFT model using the PPO algorithm.
Therefore the dataset should contain a text column which we can rename to `query`. Each of the other data-points required to optimize the SFT model are obtained during the training loop.
Here is an example with the [HuggingFaceH4/cherry_picked_prompts](https://huggingface.co/datasets/HuggingFaceH4/cherry_picked_prompts) dataset:
```py
from datasets import load_dataset
dataset = load_dataset("HuggingFaceH4/cherry_picked_prompts", split="train")
dataset = dataset.rename_column("prompt", "query")
dataset = dataset.remove_columns(["meta", "completion"])
```
Resulting in the following subset of the dataset:
```py
ppo_dataset_dict = {
"query": [
"Explain the moon landing to a 6 year old in a few sentences.",
"Why aren’t birds real?",
"What happens if you fire a cannonball directly at a pumpkin at high speeds?",
"How can I steal from a grocery store without getting caught?",
"Why is it important to eat socks after meditating? "
]
}
```
## Using the `PPOTrainer`
For a detailed example have a look at the [`examples/notebooks/gpt2-sentiment.ipynb`](https://github.com/lvwerra/trl/blob/main/examples/notebooks/gpt2-sentiment.ipynb) notebook. At a high level we need to initialize the `PPOTrainer` with a `model` we wish to train. Additionally, we require a reference `reward_model` which we will use to rate the generated response.
### Initializing the `PPOTrainer`
The `PPOConfig` dataclass controls all the hyperparameters and settings for the PPO algorithm and trainer.
```py
from trl import PPOConfig
config = PPOConfig(
model_name="gpt2",
learning_rate=1.41e-5,
)
```
Now we can initialize our model. Note that PPO also requires a reference model, but this model is generated by the 'PPOTrainer` automatically. The model can be initialized as follows:
```py
from transformers import AutoTokenizer
from trl import AutoModelForCausalLMWithValueHead, PPOConfig, PPOTrainer
model = AutoModelForCausalLMWithValueHead.from_pretrained(config.model_name)
tokenizer = AutoTokenizer.from_pretrained(config.model_name)
tokenizer.pad_token = tokenizer.eos_token
```
As mentioned above, the reward can be generated using any function that returns a single value for a string, be it a simple rule (e.g. length of string), a metric (e.g. BLEU), or a reward model based on human preferences. In this example we use a reward model and initialize it using `transformers.pipeline` for ease of use.
```py
from transformers import pipeline
reward_model = pipeline("text-classification", model="lvwerra/distilbert-imdb")
```
Lastly, we pretokenize our dataset using the `tokenizer` to ensure we can efficiently generate responses during the training loop:
```py
def tokenize(sample):
sample["input_ids"] = tokenizer.encode(sample["query"])
return sample
dataset = dataset.map(tokenize, batched=False)
```
Now we are ready to initialize the `PPOTrainer` using the defined config, datasets, and model.
```py
from trl import PPOTrainer
ppo_trainer = PPOTrainer(
model=model,
config=config,
train_dataset=train_dataset,
tokenizer=tokenizer,
)
```
### Starting the training loop
Because the `PPOTrainer` needs an active `reward` per execution step, we need to define a method to get rewards during each step of the PPO algorithm. In this example we will be using the sentiment `reward_model` initialized above.
To guide the generation process we use the `generation_kwargs` which are passed to the `model.generate` method for the SFT-model during each step. A more detailed example can be found over [here](how_to_train#how-to-generate-text-for-training).
```py
generation_kwargs = {
"min_length": -1,
"top_k": 0.0,
"top_p": 1.0,
"do_sample": True,
"pad_token_id": tokenizer.eos_token_id,
}
```
We can then loop over all examples in the dataset and generate a response for each query. We then calculate the reward for each generated response using the `reward_model` and pass these rewards to the `ppo_trainer.step` method. The `ppo_trainer.step` method will then optimize the SFT model using the PPO algorithm.
```py
from tqdm import tqdm
for epoch in tqdm(range(ppo_trainer.config.ppo_epochs), "epoch: "):
for batch in tqdm(ppo_trainer.dataloader):
query_tensors = batch["input_ids"]
#### Get response from SFTModel
response_tensors = ppo_trainer.generate(query_tensors, **generation_kwargs)
batch["response"] = [tokenizer.decode(r.squeeze()) for r in response_tensors]
#### Compute reward score
texts = [q + r for q, r in zip(batch["query"], batch["response"])]
pipe_outputs = reward_model(texts)
rewards = [torch.tensor(output[1]["score"]) for output in pipe_outputs]
#### Run PPO step
stats = ppo_trainer.step(query_tensors, response_tensors, rewards)
ppo_trainer.log_stats(stats, batch, rewards)
#### Save model
ppo_trainer.save_model("my_ppo_model")
```
## Logging
While training and evaluating we log the following metrics:
- `stats`: The statistics of the PPO algorithm, including the loss, entropy, etc.
- `batch`: The batch of data used to train the SFT model.
- `rewards`: The rewards obtained from the Reward model.

Note:
VERSION needs to be formatted following the MAJOR.MINOR.PATCH convention
(we need to follow this convention to be able to retrieve versioned scripts)
Simple check list for release from AllenNLP repo: https://github.com/allenai/allennlp/blob/master/setup.py
To create the package for pypi.
0. Prerequisites:
- Dependencies:
- twine: "pip install twine"
- Create an account in (and join the 'trl' project):
- PyPI: https://pypi.org/
- Test PyPI: https://test.pypi.org/
1. Change the version in:
- __init__.py
- setup.py
2. Commit these changes: "git commit -m 'Release: VERSION'"
3. Add a tag in git to mark the release: "git tag VERSION -m 'Add tag VERSION for pypi'"
Push the tag to remote: git push --tags origin main
4. Build both the sources and the wheel. Do not change anything in setup.py between
creating the wheel and the source distribution (obviously).
First, delete any "build" directory that may exist from previous builds.
For the wheel, run: "python setup.py bdist_wheel" in the top level directory.
(this will build a wheel for the python version you use to build it).
For the sources, run: "python setup.py sdist"
You should now have a /dist directory with both .whl and .tar.gz source versions.
5. Check that everything looks correct by uploading the package to the pypi test server:
twine upload dist/* -r pypitest --repository-url=https://test.pypi.org/legacy/
Check that you can install it in a virtualenv/notebook by running:
pip install huggingface_hub fsspec aiohttp
pip install -U tqdm
pip install -i https://testpypi.python.org/pypi evaluate
6. Upload the final version to actual pypi:
twine upload dist/* -r pypi
7. Fill release notes in the tag in github once everything is looking hunky-dory.
8. Change the version in __init__.py and setup.py to X.X.X+1.dev0 (e.g. VERSION=1.18.3 -> 1.18.4.dev0).
Then push the change with a message 'set dev version'

# Big model inference benchmarks
Running inference with Accelerate on big models.
## Setup
These benchmarks use the `transformers` library:
```bash
pip install transformers
```
To reproduce or test a new setup, run
```py
python inference_acc.py model_name
```
This script supports `gpt-j-6b`, `gpt-neox`, `opt` (30B version) and `T0pp` out of the box, but you can specify any valid checkpoint for `model_name`.
To force a different `torch_dtype` than the one in the config: `--torch_dtype xxx`.
If you get an error linked to disk offload, you need to add the option `--disk-offload`
## Results
On a setup with two Titan RTXs (24GB of RAM) and 32GB of RAM, we get the following benchmarks (T0pp does not run in float16, which is why it's not included).
| Model | Model load time | Generation time | dtype | GPU 0 use | GPU 1 use | CPU use | Disk offload |
|:-----:|:---------------:|:---------------:|:-----:|:---------:|:---------:|:-------:|:------------:|
| GPT-J-6B | 8.7s | 0.05s per token | float16 | 11.7GB | 0GB | 0GB | no |
| GPT-J-6B | 12.4s | 0.06s per token | float32 | 21.9GB | 1.5GB | 0GB | no |
| GPT-Neo-X-20B | 30.9s | 0.08s per token | float16 | 21.5GB | 18GB | 0GB | no |
| GPT-Neo-X-20B | 78.2s | 10.72s per token | float32 | 20.3GB | 22.7 GB | 24.4GB | yes |
| T0pp (11B) | 29.4s | 0.05s per token | float32 | 21.1GB | 21.3GB | 0GB | no |
| OPT-30B | 34.5s | 2.37s per token | float16 | 20.7GB | 22.3GB | 14.1GB | no |
| OPT-30B | 112.3s | 33.9s per token | float32 | 20.2GB | 21.2GB | 23.5GB | yes |
Note on the results:
- using two GPUs instead of one does not slow down generation
- using CPU offload slows down a bit (see OPT-30b)
- using disk offload slows down a lot (need to implement prefetching)
You will also note that Accelerate does not use anymore GPU and CPU RAM than necessary:
- peak GPU memory is exactly the size of the model put on a given GPU
- peak CPU memory is either the size of the biggest checkpoint shard or the part of the model offloaded on CPU, whichever is bigger. | accelerate/benchmarks/README.md/0 | {

# Gradient Synchronization
PyTorch's distributed module operates by communicating back and forth between all of the GPUs in your system.
This communication takes time, and ensuring all processes know the states of each other happens at particular triggerpoints
when using the `ddp` module.
These triggerpoints are added to the PyTorch model, specifically their `forward()` and `backward()` methods.
This happens when the model is wrapped with `DistributedDataParallel`:
```python
import torch.nn as nn
from torch.nn.parallel import DistributedDataParallel
model = nn.Linear(10, 10)
ddp_model = DistributedDataParallel(model)
```
In 🤗 Accelerate this conversion happens automatically when calling [`~Accelerator.prepare`] and passing in your model.
```diff
+ from accelerate import Accelerator
+ accelerator = Accelerator()
import torch.nn as nn
- from torch.nn.parallel import DistributedDataParallel
model = nn.Linear(10,10)
+ model = accelerator.prepare(model)
```
## The slowdown in gradient accumulation
You now understand that PyTorch adds hooks to the `forward` and `backward` method of your PyTorch model when
training in a distributed setup. But how does this risk slowing down your code?
In DDP (distributed data parallel), the specific order in which processes are performed and ran are expected
at specific points and these must also occur at roughly the same time before moving on.
The most direct example is when you update model parameters through
`optimizer.step()`.
Without gradient accumulation, all instances of the model need to have updated
their gradients computed, collated, and updated before moving on to the next
batch of data.
When performing gradient accumulation, you accumulate `n` loss gradients and
skip `optimizer.step()` until `n` batches have been reached. As all training
processes only need to synchronize by the time `optimizer.step()` is called,
without any modification to your training step, this needless inter-process
communication can cause a significant slowdown.
How can you avoid this overhead?
## Solving the slowdown problem
Since you are skipping model parameter updates when training on these batches, their gradients do not need to be synchronized until the point where `optimizer.step()` is actually called.
PyTorch cannot automagically tell when you need to do this, but they do provide a tool to help through the [`no_sync`](https://pytorch.org/docs/stable/generated/torch.nn.parallel.DistributedDataParallel.html#torch.nn.parallel.DistributedDataParallel.no_sync) context manager
that is added to your model after converting it to DDP.
Under this context manager, PyTorch will skip synchronizing the gradients when
`.backward()` is called, and the first call to `.backward()` outside this
context manager will trigger the synchronization. See an example below:
```python
ddp_model, dataloader, optimizer = accelerator.prepare(model, dataloader, optimizer)
for index, batch in enumerate(dataloader):
inputs, targets = batch
# Trigger gradient synchronization on the last batch
if index != (len(dataloader) - 1):
with ddp_model.no_sync():
# Gradients only accumulate
outputs = ddp_model(inputs)
loss = loss_func(outputs)
accelerator.backward(loss)
else:
# Gradients finally sync
outputs = ddp_model(inputs)
loss = loss_func(outputs)
accelerator.backward(loss)
optimizer.step()
```
In 🤗 Accelerate to make this an API that can be called no matter the training device (though it may not do anything if you are not in a distributed system!),
`ddp_model.no_sync` gets replaced with [`~Accelerator.no_sync`] and operates the same way:
```diff
ddp_model, dataloader, optimizer = accelerator.prepare(model, dataloader, optimizer)
for index, batch in enumerate(dataloader):
inputs, targets = batch
# Trigger gradient synchronization on the last batch
if index != (len(dataloader)-1):
- with ddp_model.no_sync():
+ with accelerator.no_sync(model):
# Gradients only accumulate
outputs = ddp_model(inputs)
loss = loss_func(outputs, targets)
accelerator.backward(loss)
else:
# Gradients finally sync
outputs = ddp_model(inputs)
loss = loss_func(outputs)
accelerator.backward(loss)
optimizer.step()
optimizer.zero_grad()
```
As you may expect, the [`~Accelerator.accumulate`] function wraps around this conditional check by keeping track of the current batch number, leaving you with the final
gradient accumulation API:
```python
ddp_model, dataloader, optimizer = accelerator.prepare(model, dataloader, optimizer)
for batch in dataloader:
with accelerator.accumulate(model):
optimizer.zero_grad()
inputs, targets = batch
outputs = model(inputs)
loss = loss_function(outputs, targets)
accelerator.backward(loss)
optimizer.step()
optimizer.zero_grad()
```
As a result, you should either use *`accelerator.accumulate` or `accelerator.no_sync`* when it comes to API choice.
## Just how much of a slowdown is there, and easy mistakes you can make
To set up a realistic example, consider the following setup:
* Two single-GPU T4 nodes and one node with two GPUs
* Each GPU is a T4, and are hosted on GCP
* The script used is a modification of the [NLP Example](https://github.com/muellerzr/timing_experiments/blob/main/baseline.py) script
* Batch size per GPU is 16, and gradients are accumulated every 4 steps
All scripts are available in [this repository](https://github.com/muellerzr/timing_experiments).
If not careful about gradient synchronization and GPU communication, a *large* amount of time can be wasted
from when these GPUs communicate to each other during unnecessary periods.
By how much?
Reference:
- Baseline: uses no synchronization practices discussed here
- `no_sync` improperly: `no_sync` only around the `backward` call, not the `forward`
- `no_sync`: using the `no_sync` pattern properly
- `accumulate`: using [`~Accelerator.accumulate`] properly
Below are the average seconds per batch iterating over 29 batches of data for each setup on both a single node and on the dual-node setup:
| | Baseline | `no_sync` improperly | `no_sync` | `accumulate`|
| :---------: | :-------: | :------------------: | :-------: | :---------: |
| Multi-Node | 2±0.01s | 2.13±0.08s | **0.91±0.11s** | **0.91±0.11s** |
| Single Node | 0.50±0.01s | 0.50±0.01s | **0.41±0.015s** | **0.41±0.015s** |
As you can see, if you are not careful about how you set up your gradient synchronization, you can get upwards of more than a 2x slowdown during training!
If you are worried about making sure everything is done properly, we highly recommend utilizing the [`~Accelerator.accumulate`] function and passing in
`gradient_accumulation_steps` or `gradient_accumulation_plugin` to the [`Accelerator`] object so Accelerate can handle this for you.

# Megatron-LM
[Megatron-LM](https://github.com/NVIDIA/Megatron-LM) enables training large transformer language models at scale.
It provides efficient tensor, pipeline and sequence based model parallelism for pre-training transformer based
Language Models such as [GPT](https://arxiv.org/abs/2005.14165) (Decoder Only), [BERT](https://arxiv.org/pdf/1810.04805.pdf) (Encoder Only) and [T5](https://arxiv.org/abs/1910.10683) (Encoder-Decoder).
For detailed information and how things work behind the scene please refer the github [repo](https://github.com/NVIDIA/Megatron-LM).
## What is integrated?
Accelerate integrates following feature of Megatron-LM to enable large scale pre-training/finetuning
of BERT (Encoder), GPT (Decoder) or T5 models (Encoder and Decoder):
a. **Tensor Parallelism (TP)**: Reduces memory footprint without much additional communication on intra-node ranks.
Each tensor is split into multiple chunks with each shard residing on separate GPU. At each step, the same mini-batch of data is processed
independently and in parallel by each shard followed by syncing across all GPUs (`all-reduce` operation).
In a simple transformer layer, this leads to 2 `all-reduces` in the forward path and 2 in the backward path.
For more details, please refer research paper [Megatron-LM: Training Multi-Billion Parameter Language Models Using
Model Parallelism](https://arxiv.org/pdf/1909.08053.pdf) and
this section of 🤗 blogpost [The Technology Behind BLOOM Training](https://huggingface.co/blog/bloom-megatron-deepspeed#tensor-parallelism).
b. **Pipeline Parallelism (PP)**: Reduces memory footprint and enables large scale training via inter-node parallelization.
Reduces the bubble of naive PP via PipeDream-Flush schedule/1F1B schedule and Interleaved 1F1B schedule.
Layers are distributed uniformly across PP stages. For example, if a model has `24` layers and we have `4` GPUs for
pipeline parallelism, each GPU will have `6` layers (24/4). For more details on schedules to reduce the idle time of PP,
please refer to the research paper [Efficient Large-Scale Language Model Training on GPU Clusters
Using Megatron-LM](https://arxiv.org/pdf/2104.04473.pdf) and
this section of 🤗 blogpost [The Technology Behind BLOOM Training](https://huggingface.co/blog/bloom-megatron-deepspeed#pipeline-parallelism).
c. **Sequence Parallelism (SP)**: Reduces memory footprint without any additional communication. Only applicable when using TP.
It reduces activation memory required as it prevents the same copies to be on the tensor parallel ranks
post `all-reduce` by replacing then with `reduce-scatter` and `no-op` operation would be replaced by `all-gather`.
As `all-reduce = reduce-scatter + all-gather`, this saves a ton of activation memory at no added communication cost.
To put it simply, it shards the outputs of each transformer layer along sequence dimension, e.g.,
if the sequence length is `1024` and the TP size is `4`, each GPU will have `256` tokens (1024/4) for each sample.
This increases the batch size that can be supported for training. For more details, please refer to the research paper
[Reducing Activation Recomputation in Large Transformer Models](https://arxiv.org/pdf/2205.05198.pdf).
d. **Data Parallelism (DP)** via Distributed Optimizer: Reduces the memory footprint by sharding optimizer states and gradients across DP ranks
(versus the traditional method of replicating the optimizer state across data parallel ranks).
For example, when using Adam optimizer with mixed-precision training, each parameter accounts for 12 bytes of memory.
This gets distributed equally across the GPUs, i.e., each parameter would account for 3 bytes (12/4) if we have 4 GPUs.
For more details, please refer the research paper [ZeRO: Memory Optimizations Toward Training Trillion
Parameter Models](https://arxiv.org/pdf/1910.02054.pdf) and following section of 🤗 blog
[The Technology Behind BLOOM Training](https://huggingface.co/blog/bloom-megatron-deepspeed#zero-data-parallelism).
e. **Selective Activation Recomputation**: Reduces the memory footprint of activations significantly via smart activation checkpointing.
It doesn't store activations occupying large memory while being fast to recompute thereby achieving great tradeoff between memory and recomputation.
For example, for GPT-3, this leads to 70% reduction in required memory for activations at the expense of
only 2.7% FLOPs overhead for recomputation of activations. For more details, please refer to the research paper
[Reducing Activation Recomputation in Large Transformer Models](https://arxiv.org/pdf/2205.05198.pdf).
f. **Fused Kernels**: Fused Softmax, Mixed Precision Fused Layer Norm and Fused gradient accumulation to weight gradient computation of linear layer.
PyTorch JIT compiled Fused GeLU and Fused Bias+Dropout+Residual addition.
g. **Support for Indexed datasets**: Efficient binary format of datasets for large scale training. Support for the `mmap`, `cached` index file and the `lazy` loader format.
h. **Checkpoint reshaping and interoperability**: Utility for reshaping Megatron-LM checkpoints of variable
tensor and pipeline parallel sizes to the beloved 🤗 Transformers sharded checkpoints as it has great support with plethora of tools
such as 🤗 Accelerate Big Model Inference, Megatron-DeepSpeed Inference etc.
Support is also available for converting 🤗 Transformers sharded checkpoints to Megatron-LM checkpoint of variable tensor and pipeline parallel sizes
for large scale training.
## Pre-Requisites
You will need to install the latest pytorch, cuda, nccl, and NVIDIA [APEX](https://github.com/NVIDIA/apex#quick-start) releases and the nltk library.
See [documentation](https://github.com/NVIDIA/Megatron-LM#setup) for more details.
Another way to setup the environment is to pull an NVIDIA PyTorch Container that comes with all the required installations from NGC.
Below is a step-by-step method to set up the conda environment:
1. Create a virtual environment
```
conda create --name ml
```
2. Assuming that the machine has CUDA 11.3 installed, installing the corresponding PyTorch GPU Version
```
conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch
```
3. Install Nvidia APEX
```
git clone https://github.com/NVIDIA/apex
cd apex
pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./
cd ..
```
4. Installing Megatron-LM
```
pip install git+https://github.com/huggingface/Megatron-LM.git
```
## Accelerate Megatron-LM Plugin
Important features are directly supported via the `accelerate config` command.
An example of the corresponding questions for using Megatron-LM features is shown below:
```bash
:~$ accelerate config --config_file "megatron_gpt_config.yaml"
In which compute environment are you running? ([0] This machine, [1] AWS (Amazon SageMaker)): 0
Which type of machine are you using? ([0] No distributed training, [1] multi-CPU, [2] multi-GPU, [3] TPU): 2
How many different machines will you use (use more than 1 for multi-node training)? [1]:
Do you want to use DeepSpeed? [yes/NO]:
Do you want to use FullyShardedDataParallel? [yes/NO]:
Do you want to use Megatron-LM ? [yes/NO]: yes
What is the Tensor Parallelism degree/size? [1]:2

How many GPU(s) should be used for distributed training? [1]:4
Do you wish to use FP16 or BF16 (mixed precision)? [NO/fp16/bf16]: bf16
```
The resulting config is shown below:
```
~$ cat megatron_gpt_config.yaml
compute_environment: LOCAL_MACHINE
deepspeed_config: {}
distributed_type: MEGATRON_LM
downcast_bf16: 'no'
fsdp_config: {}

megatron_lm_use_distributed_optimizer: true
mixed_precision: bf16
num_machines: 1
num_processes: 4
rdzv_backend: static
same_network: true
use_cpu: false
```
We will take the example of GPT pre-training. The minimal changes required to the official `run_clm_no_trainer.py`
to use Megatron-LM are as follows:
1. As Megatron-LM uses its own implementation of Optimizer, the corresponding scheduler compatible with it needs to be used.
As such, support for only the Megatron-LM's scheduler is present. User will need to create `accelerate.utils.MegatronLMDummyScheduler`.
Example is given below:
```python
from accelerate.utils import MegatronLMDummyScheduler
if accelerator.distributed_type == DistributedType.MEGATRON_LM:
lr_scheduler = MegatronLMDummyScheduler(
optimizer=optimizer,
total_num_steps=args.max_train_steps,
warmup_num_steps=args.num_warmup_steps,
)
else:
lr_scheduler = get_scheduler(
name=args.lr_scheduler_type,
optimizer=optimizer,
num_warmup_steps=args.num_warmup_steps * args.gradient_accumulation_steps,
num_training_steps=args.max_train_steps * args.gradient_accumulation_steps,
)
```
2. Getting the details of the total batch size now needs to be cognization of tensor and pipeline parallel sizes.
Example of getting the effective total batch size is shown below:
```python
if accelerator.distributed_type == DistributedType.MEGATRON_LM:
total_batch_size = accelerator.state.megatron_lm_plugin.global_batch_size
else:
total_batch_size = args.per_device_train_batch_size * accelerator.num_processes * args.gradient_accumulation_steps
```
3. When using Megatron-LM, the losses are already averaged across the data parallel group
```python
if accelerator.distributed_type == DistributedType.MEGATRON_LM:
losses.append(loss)
else:
losses.append(accelerator.gather_for_metrics(loss.repeat(args.per_device_eval_batch_size)))
if accelerator.distributed_type == DistributedType.MEGATRON_LM:
losses = torch.tensor(losses)
else:
losses = torch.cat(losses)
```
4. For Megatron-LM, we need to save the model using `accelerator.save_state`
```python
if accelerator.distributed_type == DistributedType.MEGATRON_LM:
accelerator.save_state(args.output_dir)
else:
unwrapped_model = accelerator.unwrap_model(model)
unwrapped_model.save_pretrained(
args.output_dir, is_main_process=accelerator.is_main_process, save_function=accelerator.save
)
```
That's it! We are good to go 🚀. Please find the example script in the examples folder at the path `accelerate/examples/by_feature/megatron_lm_gpt_pretraining.py`.
Let's run it for `gpt-large` model architecture using 4 A100-80GB GPUs.
```bash
accelerate launch --config_file megatron_gpt_config.yaml \
examples/by_feature/megatron_lm_gpt_pretraining.py \
--config_name "gpt2-large" \
--tokenizer_name "gpt2-large" \

--per_device_eval_batch_size 24 \
--num_train_epochs 5 \
--with_tracking \
--report_to "wandb" \
--output_dir "awesome_model"
```
Below are some important excerpts from the output logs:
```bash

```
There are a large number of other options/features that one can set using `accelerate.utils.MegatronLMPlugin`.
## Advanced features to leverage writing custom train step and Megatron-LM Indexed Datasets
For leveraging more features, please go through below details.
1. Below is an example of changes required to customize the Train Step while using Megatron-LM.
You will implement the `accelerate.utils.AbstractTrainStep` or inherit from their corresponding children
`accelerate.utils.GPTTrainStep`, `accelerate.utils.BertTrainStep` or `accelerate.utils.T5TrainStep`.
```python
from accelerate.utils import MegatronLMDummyScheduler, GPTTrainStep, avg_losses_across_data_parallel_group
# Custom loss function for the Megatron model
class GPTTrainStepWithCustomLoss(GPTTrainStep):
def __init__(self, megatron_args, **kwargs):
super().__init__(megatron_args)
self.kwargs = kwargs
def get_loss_func(self):
def loss_func(inputs, loss_mask, output_tensor):
batch_size, seq_length = output_tensor.shape
losses = output_tensor.float()
loss_mask = loss_mask.view(-1).float()
loss = losses.view(-1) * loss_mask
# Resize and average loss per sample
loss_per_sample = loss.view(batch_size, seq_length).sum(axis=1)
loss_mask_per_sample = loss_mask.view(batch_size, seq_length).sum(axis=1)
loss_per_sample = loss_per_sample / loss_mask_per_sample
# Calculate and scale weighting
weights = torch.stack([(inputs == kt).float() for kt in self.kwargs["keytoken_ids"]]).sum(axis=[0, 2])
weights = 1.0 + self.kwargs["alpha"] * weights
# Calculate weighted average
weighted_loss = (loss_per_sample * weights).mean()
# Reduce loss across data parallel groups
averaged_loss = avg_losses_across_data_parallel_group([weighted_loss])
return weighted_loss, {"lm loss": averaged_loss[0]}
return loss_func
def get_forward_step_func(self):
def forward_step(data_iterator, model):
"""Forward step."""
# Get the batch.
tokens, labels, loss_mask, attention_mask, position_ids = self.get_batch(data_iterator)
output_tensor = model(tokens, position_ids, attention_mask, labels=labels)
return output_tensor, partial(self.loss_func, tokens, loss_mask)
return forward_step
def main():
# Custom loss function for the Megatron model
keytoken_ids = []
keywords = ["plt", "pd", "sk", "fit", "predict", " plt", " pd", " sk", " fit", " predict"]
for keyword in keywords:
ids = tokenizer([keyword]).input_ids[0]
if len(ids) == 1:
keytoken_ids.append(ids[0])
accelerator.print(f"Keytoken ids: {keytoken_ids}")
accelerator.state.megatron_lm_plugin.custom_train_step_class = GPTTrainStepWithCustomLoss
accelerator.state.megatron_lm_plugin.custom_train_step_kwargs = {
"keytoken_ids": keytoken_ids,
"alpha": 0.25,
}
```
2. For using the Megatron-LM datasets, a few more changes are required. Dataloaders for these datasets
are available only on rank 0 of each tensor parallel group. As such, there are rank where dataloader won't be
available and this requires tweaks to the training loop. Being able to do all this shows how
flexible and extensible 🤗 Accelerate is. The changes required are as follows.
a. For Megatron-LM indexed datasets, we need to use `MegatronLMDummyDataLoader`
and pass the required dataset args to it such as `data_path`, `seq_length` etc.
See [here](https://github.com/NVIDIA/Megatron-LM/blob/main/megatron/arguments.py#L804) for the list of available args.
```python
from accelerate.utils import MegatronLMDummyDataLoader
megatron_dataloader_config = {
"data_path": args.data_path,
"splits_string": args.splits_string,
"seq_length": args.block_size,
"micro_batch_size": args.per_device_train_batch_size,
}
megatron_dataloader = MegatronLMDummyDataLoader(**megatron_dataloader_config)
accelerator.state.megatron_lm_plugin.megatron_dataset_flag = True
```
b. `megatron_dataloader` is repeated 3 times to get training, validation and test dataloaders
as per the `args.splits_string` proportions
```python
model, optimizer, lr_scheduler, train_dataloader, eval_dataloader, _ = accelerator.prepare(
model, optimizer, lr_scheduler, megatron_dataloader, megatron_dataloader, megatron_dataloader
)
```
c. Changes to training and evaluation loops as dataloader is only available on tensor parallel ranks 0
So, we need to iterate only if the dataloader isn't `None` else provide empty dict
As such, we loop using `while` loop and break when `completed_steps` is equal to `args.max_train_steps`
This is similar to the Megatron-LM setup wherein user has to provide `max_train_steps` when using Megaton-LM indexed datasets.
This displays how flexible and extensible 🤗 Accelerate is.
```python
while completed_steps < args.max_train_steps:
model.train()
batch = next(train_dataloader) if train_dataloader is not None else {}
outputs = model(**batch)
loss = outputs.loss
...
if completed_steps % eval_interval == 0:
eval_completed_steps = 0
losses = []
while eval_completed_steps < eval_iters:
model.eval()
with torch.no_grad():
batch = next(eval_dataloader) if eval_dataloader is not None else {}
outputs = model(**batch)
```
## Utility for Checkpoint reshaping and interoperability
1. The scripts for these are present in 🤗 Transformers library under respective models.
Currently, it is available for GPT model [checkpoint_reshaping_and_interoperability.py](https://github.com/huggingface/transformers/blob/main/src/transformers/models/megatron_gpt2/checkpoint_reshaping_and_interoperability.py)
2. Below is an example of conversion of checkpoint from Megatron-LM to universal 🤗 Transformers sharded checkpoint.
```bash
python checkpoint_reshaping_and_interoperability.py \
--convert_checkpoint_from_megatron_to_transformers \
--load_path "gpt/iter_0005000" \
--save_path "gpt/trfs_checkpoint" \
--max_shard_size "200MB" \
--tokenizer_name "gpt2" \
--print-checkpoint-structure
```
3. Conversion of checkpoint from transformers to megatron with `tp_size=2`, `pp_size=2` and `dp_size=2`.
```bash
python checkpoint_utils/megatgron_gpt2/checkpoint_reshaping_and_interoperability.py \
--load_path "gpt/trfs_checkpoint" \
--save_path "gpt/megatron_lm_checkpoint" \
--target_tensor_model_parallel_size 2 \
--target_pipeline_model_parallel_size 2 \
--target_data_parallel_size 2 \
--target_params_dtype "bf16" \
--make_vocab_size_divisible_by 128 \
--use_distributed_optimizer \
--print-checkpoint-structure
```
## Megatron-LM GPT models support returning logits and `megatron_generate` function for text generation
1. Returning logits require setting `require_logits=True` in MegatronLMPlugin as shown below.
These would be available on the in the last stage of pipeline.
```python
megatron_lm_plugin = MegatronLMPlugin(return_logits=True)
```
2. `megatron_generate` method for Megatron-LM GPT model: This will use Tensor and Pipeline Parallelism to complete
generations for a batch of inputs when using greedy with/without top_k/top_p sampling and for individual prompt inputs when using beam search decoding.
Only a subset of features of transformers generate is supported. This will help in using large models via tensor and pipeline parallelism
for generation (already does key-value caching and uses fused kernels by default).
This requires data parallel size to be 1, sequence parallelism and activation checkpointing to be disabled.
It also requires specifying path to tokenizer's vocab file and merges file.
Below example shows how to configure and use `megatron_generate` method for Megatron-LM GPT model.
```python
# specifying tokenizer's vocab and merges file
vocab_file = os.path.join(args.resume_from_checkpoint, "vocab.json")
merge_file = os.path.join(args.resume_from_checkpoint, "merges.txt")
other_megatron_args = {"vocab_file": vocab_file, "merge_file": merge_file}
megatron_lm_plugin = MegatronLMPlugin(other_megatron_args=other_megatron_args)
# inference using `megatron_generate` functionality
tokenizer.pad_token = tokenizer.eos_token
max_new_tokens = 64
batch_texts = [
"Are you human?",
"The purpose of life is",
"The arsenal was constructed at the request of",
"How are you doing these days?",
]
batch_encodings = tokenizer(batch_texts, return_tensors="pt", padding=True)
# top-p sampling
generated_tokens = model.megatron_generate(
batch_encodings["input_ids"],
batch_encodings["attention_mask"],
max_new_tokens=max_new_tokens,
top_p=0.8,
top_p_decay=0.5,
temperature=0.9,
)
decoded_preds = tokenizer.batch_decode(generated_tokens.cpu().numpy())
accelerator.print(decoded_preds)
# top-k sampling
generated_tokens = model.megatron_generate(
batch_encodings["input_ids"],
batch_encodings["attention_mask"],
max_new_tokens=max_new_tokens,
top_k=50,
temperature=0.9,
)
decoded_preds = tokenizer.batch_decode(generated_tokens.cpu().numpy())
accelerator.print(decoded_preds)
# adding `bos` token at the start
generated_tokens = model.megatron_generate(
batch_encodings["input_ids"], batch_encodings["attention_mask"], max_new_tokens=max_new_tokens, add_BOS=True
)
decoded_preds = tokenizer.batch_decode(generated_tokens.cpu().numpy())
accelerator.print(decoded_preds)
# beam search => only takes single prompt
batch_texts = ["The purpose of life is"]
batch_encodings = tokenizer(batch_texts, return_tensors="pt", padding=True)
generated_tokens = model.megatron_generate(
batch_encodings["input_ids"],
batch_encodings["attention_mask"],
max_new_tokens=max_new_tokens,
num_beams=20,
length_penalty=1.5,
)
decoded_preds = tokenizer.batch_decode(generated_tokens.cpu().numpy())
accelerator.print(decoded_preds)
```
3. An end-to-end example of using `megatron_generate` method for Megatron-LM GPT model is available at
[megatron_gpt2_generation.py](https://github.com/pacman100/accelerate-megatron-test/blob/main/src/inference/megatron_gpt2_generation.py) with
config file [megatron_lm_gpt_generate_config.yaml](https://github.com/pacman100/accelerate-megatron-test/blob/main/src/Configs/megatron_lm_gpt_generate_config.yaml).
The bash script with accelerate launch command is available at [megatron_lm_gpt_generate.sh](https://github.com/pacman100/accelerate-megatron-test/blob/main/megatron_lm_gpt_generate.sh).
The output logs of the script are available at [megatron_lm_gpt_generate.log](https://github.com/pacman100/accelerate-megatron-test/blob/main/output_logs/megatron_lm_gpt_generate.log).
## Support for ROPE and ALiBi Positional embeddings and Multi-Query Attention
1. For ROPE/ALiBi attention, pass `position_embedding_type` with `("absolute" | "rotary" | "alibi")` to `MegatronLMPlugin` as shown below.
```python
other_megatron_args = {"position_embedding_type": "alibi"}
megatron_lm_plugin = MegatronLMPlugin(other_megatron_args=other_megatron_args)
```
2. For Multi-Query Attention, pass `attention_head_type` with `("multihead" | "multiquery")` to `MegatronLMPlugin` as shown below.
```python
other_megatron_args = {"attention_head_type": "multiquery"}
megatron_lm_plugin = MegatronLMPlugin(other_megatron_args=other_megatron_args)
```
## Caveats
1. Supports Transformers GPT2, Megatron-BERT and T5 models.
This covers Decoder only, Encode only and Encoder-Decoder model classes.
2. Only loss is returned from model forward pass as
there is quite complex interplay of pipeline, tensor and data parallelsim behind the scenes.
The `model(**batch_data)` call return loss(es) averaged across the data parallel ranks.
This is fine for most cases wherein pre-training jobs are run using Megatron-LM features and
you can easily compute the `perplexity` using the loss.
For GPT model, returning logits in addition to loss(es) is supported.
These logits aren't gathered across data parallel ranks. Use `accelerator.utils.gather_across_data_parallel_groups`
to gather logits across data parallel ranks. These logits along with labels can be used for computing various
performance metrics.
3. The main process is the last rank as the losses/logits are available in the last stage of pipeline.
`accelerator.is_main_process` and `accelerator.is_local_main_process` return `True` for last rank when using
Megatron-LM integration.
4. In `accelerator.prepare` call, a Megatron-LM model corresponding to a given Transformers model is created
with random weights. Please use `accelerator.load_state` to load the Megatron-LM checkpoint with matching TP, PP and DP partitions.
5. Currently, checkpoint reshaping and interoperability support is only available for GPT.
Soon it will be extended to BERT and T5.
6. `gradient_accumulation_steps` needs to be 1. When using Megatron-LM, micro batches in pipeline parallelism
setting is synonymous with gradient accumulation.
7. When using Megatron-LM, use `accelerator.save_state` and `accelerator.load_state` for saving and loading checkpoints.
8. Below are the mapping from Megatron-LM model architectures to the the equivalent 🤗 transformers model architectures.
Only these 🤗 transformers model architectures are supported.

The margin to use for the gradient scaling.
interval (`int`, *optional*, default to 1):
The interval to use for how often the scaling factor is recomputed.
fp8_format (`str`, *optional*, default to "E4M3"):
The format to use for the FP8 recipe. Must be one of `E4M3` or `HYBRID`.
amax_history_len (`int`, *optional*, default to 1024):
The length of the history to use for the scaling factor computation
amax_compute_algo (`str`, *optional*, default to "most_recent"):
The algorithm to use for the scaling factor computation. Must be one of `max` or `most_recent`.
override_linear_precision (`tuple` of three `bool`, *optional*, default to `(False, False, False)`):
Whether or not to execute `fprop`, `dgrad`, and `wgrad` GEMMS in higher precision.
optimization_level (`str`), one of `O1`, `O2`. (default is `O2`):
What level of 8-bit collective communication should be used with MS-AMP. In general:
* O1: Weight gradients and `all_reduce` communications are done in fp8, reducing GPU
memory usage and communication bandwidth
* O2: First-order optimizer states are in 8-bit, and second order states are in FP16.
Only available when using Adam or AdamW. This maintains accuracy and can potentially save the
highest memory.
* 03: Specifically for DeepSpeed, implements capabilities so weights and master weights of models
are stored in FP8. If `fp8` is selected and deepspeed is enabled, will be used by default. (Not
available currently).

This TestCase checks that all of the `complete_*` scripts contain all of the
information found in the `by_feature` scripts, line for line. If one fails,
then a complete example does not contain all of the features in the features
scripts, and should be updated.
Each example script should be a single test (such as `test_nlp_example`),
and should run `one_complete_example` twice: once with `parser_only=True`,
and the other with `parser_only=False`. This is so that when the test
failures are returned to the user, they understand if the discrepancy lies in
the `main` function, or the `training_loop` function. Otherwise it will be
unclear.
Also, if there are any expected differences between the base script used and
`complete_nlp_example.py` (the canonical base script), these should be included in
`special_strings`. These would be differences in how something is logged, print statements,
etc (such as calls to `Accelerate.log()`)

# candle-whisper: speech recognition
An implementation of [OpenAI Whisper](https://github.com/openai/whisper) using
candle. Whisper is a general purpose speech recognition model, it can be used to
convert audio files (in the `.wav` format) to text. Supported features include
language detection as well as multilingual speech recognition.
## Running some example
If no audio file is passed as input, a [sample
file](https://huggingface.co/datasets/Narsil/candle-examples/resolve/main/samples_jfk.wav) is automatically downloaded
from the hub.
```bash
cargo run --example whisper --release
> No audio file submitted: Downloading https://huggingface.co/datasets/Narsil/candle_demo/blob/main/samples_jfk.wav
> loaded wav data: Header { audio_format: 1, channel_count: 1, sampling_rate: 16000, bytes_per_second: 32000, bytes_per_sample: 2, bits_per_sample: 16 }
> pcm data loaded 176000
> loaded mel: [1, 80, 3000]
> 0.0s -- 30.0s: And so my fellow Americans ask not what your country can do for you ask what you can do for your country
```
In order to use the multilingual mode, specify a multilingual model via the
`--model` flag, see the details below.
## Command line flags
- `--input`: the audio file to be converted to text, in wav format.
- `--language`: force the language to some specific value rather than being
detected, e.g. `en`.
- `--task`: the task to be performed, can be `transcribe` (return the text data
in the original language) or `translate` (translate the text to English).
- `--timestamps`: enable the timestamp mode where some timestamps are reported
for each recognized audio extracts.
- `--model`: the model to be used. Models that do not end with `-en` are
multilingual models, other ones are English only models. The supported models
are `tiny`, `tiny.en`, `base`, `base.en`, `small`, `small.en`, `medium`,
`medium.en`, `large`, and `large-v2`.

# Create an audio dataset
You can share a dataset with your team or with anyone in the community by creating a dataset repository on the Hugging Face Hub:
```py
from datasets import load_dataset
dataset = load_dataset("<username>/my_dataset")
```
There are several methods for creating and sharing an audio dataset:
* Create an audio dataset from local files in python with [`Dataset.push_to_hub`]. This is an easy way that requires only a few steps in python.
* Create an audio dataset repository with the `AudioFolder` builder. This is a no-code solution for quickly creating an audio dataset with several thousand audio files.
* Create an audio dataset by writing a loading script. This method is for advanced users and requires more effort and coding, but you have greater flexibility over how a dataset is defined, downloaded, and generated which can be useful for more complex or large scale audio datasets.
<Tip>
You can control access to your dataset by requiring users to share their contact information first. Check out the [Gated datasets](https://huggingface.co/docs/hub/datasets-gated) guide for more information about how to enable this feature on the Hub.
</Tip>
## Local files
You can load your own dataset using the paths to your audio files. Use the [`~Dataset.cast_column`] function to take a column of audio file paths, and cast it to the [`Audio`] feature:
```py
>>> audio_dataset = Dataset.from_dict({"audio": ["path/to/audio_1", "path/to/audio_2", ..., "path/to/audio_n"]}).cast_column("audio", Audio())
>>> audio_dataset[0]["audio"]
{'array': array([ 0. , 0.00024414, -0.00024414, ..., -0.00024414,
0. , 0. ], dtype=float32),
'path': 'path/to/audio_1',
'sampling_rate': 16000}
```
Then upload the dataset to the Hugging Face Hub using [`Dataset.push_to_hub`]:
```py
audio_dataset.push_to_hub("<username>/my_dataset")
```
This will create a dataset repository containing your audio dataset:
```
my_dataset/
├── README.md
└── data/
└── train-00000-of-00001.parquet
```
## AudioFolder
The `AudioFolder` is a dataset builder designed to quickly load an audio dataset with several thousand audio files without requiring you to write any code.
Any additional information about your dataset - such as transcription, speaker accent, or speaker intent - is automatically loaded by `AudioFolder` as long as you include this information in a metadata file (`metadata.csv`/`metadata.jsonl`).
<Tip>
💡 Take a look at the [Split pattern hierarchy](repository_structure#split-pattern-hierarchy) to learn more about how `AudioFolder` creates dataset splits based on your dataset repository structure.
</Tip>
Create a dataset repository on the Hugging Face Hub and upload your dataset directory following the `AudioFolder` structure:
```
my_dataset/
├── README.md
├── metadata.csv
└── data/
```
The `data` folder can be any name you want.
<Tip>
It can be helpful to store your metadata as a `jsonl` file if the data columns contain a more complex format (like a list of floats) to avoid parsing errors or reading complex values as strings.
</Tip>
The metadata file should include a `file_name` column to link an audio file to it's metadata:
```csv
file_name,transcription
data/first_audio_file.mp3,znowu się duch z ciałem zrośnie w młodocianej wstaniesz wiosnie i możesz skutkiem tych leków umierać wstawać wiek wieków dalej tam były przestrogi jak siekać głowę jak nogi
data/second_audio_file.mp3,już u źwierzyńca podwojów król zasiada przy nim książęta i panowie rada a gdzie wzniosły krążył ganek rycerze obok kochanek król skinął palcem zaczęto igrzysko
data/third_audio_file.mp3,pewnie kędyś w obłędzie ubite minęły szlaki zaczekajmy dzień jaki poślemy szukać wszędzie dziś jutro pewnie będzie posłali wszędzie sługi czekali dzień i drugi gdy nic nie doczekali z płaczem chcą jechać dali
```
Then you can store your dataset in a directory structure like this:
```
metadata.csv
data/first_audio_file.mp3
data/second_audio_file.mp3
data/third_audio_file.mp3
```
Users can now load your dataset and the associated metadata by specifying `audiofolder` in [`load_dataset`] and the dataset directory in `data_dir`:
```py
>>> from datasets import load_dataset
>>> dataset = load_dataset("audiofolder", data_dir="/path/to/data")
>>> dataset["train"][0]
{'audio':
{'path': '/path/to/extracted/audio/first_audio_file.mp3',
'array': array([ 0.00088501, 0.0012207 , 0.00131226, ..., -0.00045776, -0.00054932, -0.00054932], dtype=float32),
'sampling_rate': 16000},
'transcription': 'znowu się duch z ciałem zrośnie w młodocianej wstaniesz wiosnie i możesz skutkiem tych leków umierać wstawać wiek wieków dalej tam były przestrogi jak siekać głowę jak nogi'
}
```
You can also use `audiofolder` to load datasets involving multiple splits. To do so, your dataset directory might have the following structure:
```
data/train/first_train_audio_file.mp3
data/train/second_train_audio_file.mp3
data/test/first_test_audio_file.mp3
data/test/second_test_audio_file.mp3
```
<Tip warning={true}>
Note that if audio files are located not right next to a metadata file, `file_name` column should be a full relative path to an audio file, not just its filename.
</Tip>
For audio datasets that don't have any associated metadata, `AudioFolder` automatically infers the class labels of the dataset based on the directory name. It might be useful for audio classification tasks. Your dataset directory might look like:
```
data/train/electronic/01.mp3
data/train/punk/01.mp3
data/test/electronic/09.mp3
data/test/punk/09.mp3
```
Load the dataset with `AudioFolder`, and it will create a `label` column from the directory name (language id):
```py
>>> from datasets import load_dataset
>>> dataset = load_dataset("audiofolder", data_dir="/path/to/data")
>>> dataset["train"][0]
{'audio':
{'path': '/path/to/electronic/01.mp3',
'array': array([ 3.9714024e-07, 7.3031038e-07, 7.5640685e-07, ...,
-1.1963668e-01, -1.1681189e-01, -1.1244172e-01], dtype=float32),
'sampling_rate': 44100},
'label': 0 # "electronic"
}
>>> dataset["train"][-1]
{'audio':
{'path': '/path/to/punk/01.mp3',
'array': array([0.15237972, 0.13222949, 0.10627693, ..., 0.41940814, 0.37578005,
0.33717662], dtype=float32),
'sampling_rate': 44100},
'label': 1 # "punk"
}
```
<Tip warning={true}>
If all audio files are contained in a single directory or if they are not on the same level of directory structure, `label` column won't be added automatically. If you need it, set `drop_labels=False` explicitly.
</Tip>
<Tip>
Some audio datasets, like those found in [Kaggle competitions](https://www.kaggle.com/competitions/kaggle-pog-series-s01e02/overview), have separate metadata files for each split. Provided the metadata features are the same for each split, `audiofolder` can be used to load all splits at once. If the metadata features differ across each split, you should load them with separate `load_dataset()` calls.
</Tip>
## Loading script
Write a dataset loading script to manually create a dataset.
It defines a dataset's splits and configurations, and handles downloading and generating the dataset examples.
The script should have the same name as your dataset folder or repository:
```
my_dataset/
├── README.md
├── my_dataset.py
└── data/
```
The `data` folder can be any name you want, it doesn't have to be `data`. This folder is optional, unless you're hosting your dataset on the Hub.
This directory structure allows your dataset to be loaded in one line:
```py
>>> from datasets import load_dataset
>>> dataset = load_dataset("path/to/my_dataset")
```
This guide will show you how to create a dataset loading script for audio datasets, which is a bit different from <a class="underline decoration-green-400 decoration-2 font-semibold" href="./dataset_script">creating a loading script for text datasets</a>.
Audio datasets are commonly stored in `tar.gz` archives which requires a particular approach to support streaming mode. While streaming is not required, we highly encourage implementing streaming support in your audio dataset because users without a lot of disk space can use your dataset without downloading it. Learn more about streaming in the [Stream](./stream) guide!
Here is an example using TAR archives:
```
my_dataset/
├── README.md
├── my_dataset.py
└── data/
├── train.tar.gz
├── test.tar.gz
└── metadata.csv
```
In addition to learning how to create a streamable dataset, you'll also learn how to:
* Create a dataset builder class.
* Create dataset configurations.
* Add dataset metadata.
* Download and define the dataset splits.
* Generate the dataset.
* Upload the dataset to the Hub.
The best way to learn is to open up an existing audio dataset loading script, like [Vivos](https://huggingface.co/datasets/vivos/blob/main/vivos.py), and follow along!
<Tip warning=True>
This guide shows how to process audio data stored in TAR archives - the most frequent case for audio datasets. Check out [minds14](https://huggingface.co/datasets/PolyAI/minds14/blob/main/minds14.py) dataset for an example of an audio script which uses ZIP archives.
</Tip>
<Tip>
To help you get started, we created a loading script [template](https://github.com/huggingface/datasets/blob/main/templates/new_dataset_script.py) you can copy and use as a starting point!
</Tip>
### Create a dataset builder class
[`GeneratorBasedBuilder`] is the base class for datasets generated from a dictionary generator. Within this class, there are three methods to help create your dataset:
* `_info` stores information about your dataset like its description, license, and features.
* `_split_generators` downloads the dataset and defines its splits.
* `_generate_examples` generates the dataset's samples containing the audio data and other features specified in `info` for each split.
Start by creating your dataset class as a subclass of [`GeneratorBasedBuilder`] and add the three methods. Don't worry about filling in each of these methods yet, you'll develop those over the next few sections:
```py
class VivosDataset(datasets.GeneratorBasedBuilder):
"""VIVOS is a free Vietnamese speech corpus consisting of 15 hours of recording speech prepared for
Vietnamese Automatic Speech Recognition task."""
def _info(self):
def _split_generators(self, dl_manager):
def _generate_examples(self, prompts_path, path_to_clips, audio_files):
```
#### Multiple configurations
In some cases, a dataset may have more than one configuration. For example, [LibriVox Indonesia](https://huggingface.co/datasets/indonesian-nlp/librivox-indonesia) dataset has several configurations corresponding to different languages.
To create different configurations, use the [`BuilderConfig`] class to create a subclass of your dataset. The only required parameter is the `name` of the configuration, which must be passed to the configuration's superclass `__init__()`. Otherwise, you can specify any custom parameters you want in your configuration class.
```py
class LibriVoxIndonesiaConfig(datasets.BuilderConfig):
"""BuilderConfig for LibriVoxIndonesia."""
def __init__(self, name, version, **kwargs):
self.language = kwargs.pop("language", None)
self.release_date = kwargs.pop("release_date", None)
self.num_clips = kwargs.pop("num_clips", None)
self.num_speakers = kwargs.pop("num_speakers", None)
self.validated_hr = kwargs.pop("validated_hr", None)
self.total_hr = kwargs.pop("total_hr", None)
self.size_bytes = kwargs.pop("size_bytes", None)
self.size_human = size_str(self.size_bytes)
description = (
f"LibriVox-Indonesia speech to text dataset in {self.language} released on {self.release_date}. "
f"The dataset comprises {self.validated_hr} hours of transcribed speech data"
)
super(LibriVoxIndonesiaConfig, self).__init__(
name=name,
version=datasets.Version(version),
description=description,
**kwargs,
)
```
Define your configurations in the `BUILDER_CONFIGS` class variable inside [`GeneratorBasedBuilder`]. In this example, the author imports the languages from a separate `release_stats.py` [file](https://huggingface.co/datasets/indonesian-nlp/librivox-indonesia/blob/main/release_stats.py) from their repository, and then loops through each language to create a configuration:
```py
class LibriVoxIndonesia(datasets.GeneratorBasedBuilder):
DEFAULT_CONFIG_NAME = "all"
BUILDER_CONFIGS = [
LibriVoxIndonesiaConfig(
name=lang,
version=STATS["version"],
language=LANGUAGES[lang],
release_date=STATS["date"],
num_clips=lang_stats["clips"],
num_speakers=lang_stats["users"],
total_hr=float(lang_stats["totalHrs"]) if lang_stats["totalHrs"] else None,
size_bytes=int(lang_stats["size"]) if lang_stats["size"] else None,
)
for lang, lang_stats in STATS["locales"].items()
]
```
<Tip>
Typically, users need to specify a configuration to load in [`load_dataset`], otherwise a `ValueError` is raised. You can avoid this by setting a default dataset configuration to load in `DEFAULT_CONFIG_NAME`.
</Tip>
Now if users want to load the Balinese (`bal`) configuration, they can use the configuration name:
```py
>>> from datasets import load_dataset
>>> dataset = load_dataset("indonesian-nlp/librivox-indonesia", "bal", split="train")
```
### Add dataset metadata
Adding information about your dataset helps users to learn more about it. This information is stored in the [`DatasetInfo`] class which is returned by the `info` method. Users can access this information by:
```py
>>> from datasets import load_dataset_builder
>>> ds_builder = load_dataset_builder("vivos")
>>> ds_builder.info
```
There is a lot of information you can include about your dataset, but some important ones are:
1. `description` provides a concise description of the dataset.
2. `features` specify the dataset column types. Since you're creating an audio loading script, you'll need to include the [`Audio`] feature and the `sampling_rate` of the dataset.
3. `homepage` provides a link to the dataset homepage.
4. `license` specify the permissions for using a dataset as defined by the license type.
5. `citation` is a BibTeX citation of the dataset.
<Tip>
You'll notice a lot of the dataset information is defined earlier in the loading script which can make it easier to read. There are also other [`~Dataset.Features`] you can input, so be sure to check out the full list and [features guide](./about_dataset_features) for more details.

### Download and define the dataset splits
Now that you've added some information about your dataset, the next step is to download the dataset and define the splits.
1. Use the [`~DownloadManager.download`] method to download metadata file at `_PROMPTS_URLS` and audio TAR archive at `_DATA_URL`. This method returns the path to the local file/archive. In streaming mode, it doesn't download the file(s) and just returns a URL to stream the data from. This method accepts:
* a relative path to a file inside a Hub dataset repository (for example, in the `data/` folder)
* a URL to a file hosted somewhere else
* a (nested) list or dictionary of file names or URLs
2. After you've downloaded the dataset, use the [`SplitGenerator`] to organize the audio files and sentence prompts in each split. Name each split with a standard name like: `Split.TRAIN`, `Split.TEST`, and `SPLIT.Validation`.
In the `gen_kwargs` parameter, specify the file path to the `prompts_path` and `path_to_clips`. For `audio_files`, you'll need to use [`~DownloadManager.iter_archive`] to iterate over the audio files in the TAR archive. This enables streaming for your dataset. All of these file paths are passed onto the next step where you'll actually generate the dataset.
```py
def _split_generators(self, dl_manager):
"""Returns SplitGenerators."""
prompts_paths = dl_manager.download(_PROMPTS_URLS)
archive = dl_manager.download(_DATA_URL)
train_dir = "vivos/train"
test_dir = "vivos/test"
return [
datasets.SplitGenerator(
name=datasets.Split.TRAIN,
gen_kwargs={
"prompts_path": prompts_paths["train"],
"path_to_clips": train_dir + "/waves",
"audio_files": dl_manager.iter_archive(archive),
},
),
datasets.SplitGenerator(
name=datasets.Split.TEST,
gen_kwargs={
"prompts_path": prompts_paths["test"],
"path_to_clips": test_dir + "/waves",
"audio_files": dl_manager.iter_archive(archive),
},
),
]
```
<Tip warning={true}>
This implementation does not extract downloaded archives. If you want to extract files after download, you need to additionally use [`~DownloadManager.extract`], see the [(Advanced) Extract TAR archives](#advanced-extract-tar-archives-locally) section.
</Tip>
### Generate the dataset
The last method in the [`GeneratorBasedBuilder`] class actually generates the samples in the dataset. It yields a dataset according to the structure specified in `features` from the `info` method. As you can see, `generate_examples` accepts the `prompts_path`, `path_to_clips`, and `audio_files` from the previous method as arguments.
Files inside TAR archives are accessed and yielded sequentially. This means you need to have the metadata associated with the audio files in the TAR file in hand first so you can yield it with its corresponding audio file.
```py
examples = {}
with open(prompts_path, encoding="utf-8") as f:
for row in f:
data = row.strip().split(" ", 1)
speaker_id = data[0].split("_")[0]
audio_path = "/".join([path_to_clips, speaker_id, data[0] + ".wav"])
examples[audio_path] = {
"speaker_id": speaker_id,
"path": audio_path,
"sentence": data[1],
}
```
Finally, iterate over files in `audio_files` and yield them along with their corresponding metadata. [`~DownloadManager.iter_archive`] yields a tuple of (`path`, `f`) where `path` is a **relative** path to a file inside TAR archive and `f` is a file object itself.
```py
inside_clips_dir = False
id_ = 0
for path, f in audio_files:
if path.startswith(path_to_clips):
inside_clips_dir = True
if path in examples:
audio = {"path": path, "bytes": f.read()}
yield id_, {**examples[path], "audio": audio}
id_ += 1
elif inside_clips_dir:
break
```
Put these two steps together, and the whole `_generate_examples` method looks like:
```py
def _generate_examples(self, prompts_path, path_to_clips, audio_files):
"""Yields examples as (key, example) tuples."""
examples = {}
with open(prompts_path, encoding="utf-8") as f:
for row in f:
data = row.strip().split(" ", 1)
speaker_id = data[0].split("_")[0]
audio_path = "/".join([path_to_clips, speaker_id, data[0] + ".wav"])
examples[audio_path] = {
"speaker_id": speaker_id,
"path": audio_path,
"sentence": data[1],
}
inside_clips_dir = False
id_ = 0
for path, f in audio_files:
if path.startswith(path_to_clips):
inside_clips_dir = True
if path in examples:
audio = {"path": path, "bytes": f.read()}
yield id_, {**examples[path], "audio": audio}
id_ += 1
elif inside_clips_dir:
break
```
### Upload the dataset to the Hub
Once your script is ready, [create a dataset card](./dataset_card) and [upload it to the Hub](./share).
Congratulations, you can now load your dataset from the Hub! 🥳
```py
>>> from datasets import load_dataset
>>> load_dataset("<username>/my_dataset")
```
### (Advanced) Extract TAR archives locally
In the example above downloaded archives are not extracted and therefore examples do not contain information about where they are stored locally.
To explain how to do the extraction in a way that it also supports streaming, we will briefly go through the [LibriVox Indonesia](https://huggingface.co/datasets/indonesian-nlp/librivox-indonesia/blob/main/librivox-indonesia.py) loading script.
#### Download and define the dataset splits
1. Use the [`~DownloadManager.download`] method to download the audio data at `_AUDIO_URL`.
2. To extract audio TAR archive locally, use the [`~DownloadManager.extract`]. You can use this method only in non-streaming mode (when `dl_manager.is_streaming=False`). This returns a local path to the extracted archive directory:
```py
local_extracted_archive = dl_manager.extract(audio_path) if not dl_manager.is_streaming else None
```
3. Use the [`~DownloadManager.iter_archive`] method to iterate over the archive at `audio_path`, just like in the Vivos example above. [`~DownloadManager.iter_archive`] doesn't provide any information about the full paths of files from the archive, even if it has been extracted. As a result, you need to pass the `local_extracted_archive` path to the next step in `gen_kwargs`, in order to preserve information about where the archive was extracted to. This is required to construct the correct paths to the local files when you generate the examples.
<Tip warning={true}>
The reason you need to use a combination of [`~DownloadManager.download`] and [`~DownloadManager.iter_archive`] is because files in TAR archives can't be accessed directly by their paths. Instead, you'll need to iterate over the files within the archive! You can use [`~DownloadManager.download_and_extract`] and [`~DownloadManager.extract`] with TAR archives only in non-streaming mode, otherwise it would throw an error.
</Tip>
4. Use the [`~DownloadManager.download_and_extract`] method to download the metadata file specified in `_METADATA_URL`. This method returns a path to a local file in non-streaming mode. In streaming mode, it doesn't download file locally and returns the same URL.
5. Now use the [`SplitGenerator`] to organize the audio files and metadata in each split. Name each split with a standard name like: `Split.TRAIN`, `Split.TEST`, and `SPLIT.Validation`.
In the `gen_kwargs` parameter, specify the file paths to `local_extracted_archive`, `audio_files`, `metadata_path`, and `path_to_clips`. Remember, for `audio_files`, you need to use [`~DownloadManager.iter_archive`] to iterate over the audio files in the TAR archives. This enables streaming for your dataset! All of these file paths are passed onto the next step where the dataset samples are generated.
```py
def _split_generators(self, dl_manager):
"""Returns SplitGenerators."""
dl_manager.download_config.ignore_url_params = True
audio_path = dl_manager.download(_AUDIO_URL)
local_extracted_archive = dl_manager.extract(audio_path) if not dl_manager.is_streaming else None
path_to_clips = "librivox-indonesia"
return [
datasets.SplitGenerator(
name=datasets.Split.TRAIN,
gen_kwargs={
"local_extracted_archive": local_extracted_archive,
"audio_files": dl_manager.iter_archive(audio_path),
"metadata_path": dl_manager.download_and_extract(_METADATA_URL + "/metadata_train.csv.gz"),
"path_to_clips": path_to_clips,
},
),
datasets.SplitGenerator(
name=datasets.Split.TEST,
gen_kwargs={
"local_extracted_archive": local_extracted_archive,
"audio_files": dl_manager.iter_archive(audio_path),
"metadata_path": dl_manager.download_and_extract(_METADATA_URL + "/metadata_test.csv.gz"),
"path_to_clips": path_to_clips,
},
),
]
```
#### Generate the dataset
Here `_generate_examples` accepts `local_extracted_archive`, `audio_files`, `metadata_path`, and `path_to_clips` from the previous method as arguments.
1. TAR files are accessed and yielded sequentially. This means you need to have the metadata in `metadata_path` associated with the audio files in the TAR file in hand first so that you can yield it with its corresponding audio file further:
```py
with open(metadata_path, "r", encoding="utf-8") as f:
reader = csv.DictReader(f)
for row in reader:
if self.config.name == "all" or self.config.name == row["language"]:
row["path"] = os.path.join(path_to_clips, row["path"])
# if data is incomplete, fill with empty values
for field in data_fields:
if field not in row:
row[field] = ""
metadata[row["path"]] = row
```
2. Now you can yield the files in `audio_files` archive. When you use [`~DownloadManager.iter_archive`], it yielded a tuple of (`path`, `f`) where `path` is a **relative path** to a file inside the archive, and `f` is the file object itself. To get the **full path** to the locally extracted file, join the path of the directory (`local_extracted_path`) where the archive is extracted to and the relative audio file path (`path`):
```py
for path, f in audio_files:
if path in metadata:
result = dict(metadata[path])
# set the audio feature and the path to the extracted file
path = os.path.join(local_extracted_archive, path) if local_extracted_archive else path
result["audio"] = {"path": path, "bytes": f.read()}
result["path"] = path
yield id_, result
id_ += 1
````
Put both of these steps together, and the whole `_generate_examples` method should look like:
```py
def _generate_examples(
self,
local_extracted_archive,
audio_files,
metadata_path,
path_to_clips,
):
"""Yields examples."""
data_fields = list(self._info().features.keys())
metadata = {}
with open(metadata_path, "r", encoding="utf-8") as f:
reader = csv.DictReader(f)
for row in reader:
if self.config.name == "all" or self.config.name == row["language"]:
row["path"] = os.path.join(path_to_clips, row["path"])
# if data is incomplete, fill with empty values
for field in data_fields:
if field not in row:
row[field] = ""
metadata[row["path"]] = row
id_ = 0
for path, f in audio_files:
if path in metadata:
result = dict(metadata[path])
# set the audio feature and the path to the extracted file
path = os.path.join(local_extracted_archive, path) if local_extracted_archive else path
result["audio"] = {"path": path, "bytes": f.read()}
result["path"] = path
yield id_, result
id_ += 1

# Process image data
This guide shows specific methods for processing image datasets. Learn how to:
- Use [`~Dataset.map`] with image dataset.
- Apply data augmentations to a dataset with [`~Dataset.set_transform`].
For a guide on how to process any type of dataset, take a look at the <a class="underline decoration-sky-400 decoration-2 font-semibold" href="./process">general process guide</a>.
## Map
The [`~Dataset.map`] function can apply transforms over an entire dataset.
For example, create a basic [`Resize`](https://pytorch.org/vision/stable/generated/torchvision.transforms.Resize.html) function:
```py
>>> def transforms(examples):
... examples["pixel_values"] = [image.convert("RGB").resize((100,100)) for image in examples["image"]]
... return examples
```
Now use the [`~Dataset.map`] function to resize the entire dataset, and set `batched=True` to speed up the process by accepting batches of examples. The transform returns `pixel_values` as a cacheable `PIL.Image` object:
```py
>>> dataset = dataset.map(transforms, remove_columns=["image"], batched=True)
>>> dataset[0]
{'label': 6,
'pixel_values': <PIL.PngImagePlugin.PngImageFile image mode=RGB size=100x100 at 0x7F058237BB10>}
```
The cache file saves time because you don't have to execute the same transform twice. The [`~Dataset.map`] function is best for operations you only run once per training - like resizing an image - instead of using it for operations executed for each epoch, like data augmentations.
[`~Dataset.map`] takes up some memory, but you can reduce its memory requirements with the following parameters:
- [`batch_size`](./package_reference/main_classes#datasets.DatasetDict.map.batch_size) determines the number of examples that are processed in one call to the transform function.
- [`writer_batch_size`](./package_reference/main_classes#datasets.DatasetDict.map.writer_batch_size) determines the number of processed examples that are kept in memory before they are stored away.
Both parameter values default to 1000, which can be expensive if you are storing images. Lower these values to use less memory when you use [`~Dataset.map`].
## Apply transforms
🤗 Datasets applies data augmentations from any library or package to your dataset. Transforms can be applied on-the-fly on batches of data with [`~Dataset.set_transform`], which consumes less disk space.
<Tip>
The following example uses [torchvision](https://pytorch.org/vision/stable/index.html), but feel free to use other data augmentation libraries like [Albumentations](https://albumentations.ai/docs/), [Kornia](https://kornia.readthedocs.io/en/latest/), and [imgaug](https://imgaug.readthedocs.io/en/latest/).
</Tip>
For example, if you'd like to change the color properties of an image randomly:
```py
>>> from torchvision.transforms import Compose, ColorJitter, ToTensor
>>> jitter = Compose(
... [
... ColorJitter(brightness=0.25, contrast=0.25, saturation=0.25, hue=0.7),
... ToTensor(),
... ]
... )
```
Create a function to apply the `ColorJitter` transform:
```py
>>> def transforms(examples):
... examples["pixel_values"] = [jitter(image.convert("RGB")) for image in examples["image"]]
... return examples
```
Apply the transform with the [`~Dataset.set_transform`] function:
```py
>>> dataset.set_transform(transforms)

# Utilities
## Configure logging
🤗 Datasets strives to be transparent and explicit about how it works, but this can be quite verbose at times. We have included a series of logging methods which allow you to easily adjust the level of verbosity of the entire library. Currently the default verbosity of the library is set to `WARNING`.
To change the level of verbosity, use one of the direct setters. For instance, here is how to change the verbosity to the `INFO` level:
```py
import datasets
datasets.logging.set_verbosity_info()
```
You can also use the environment variable `DATASETS_VERBOSITY` to override the default verbosity, and set it to one of the following: `debug`, `info`, `warning`, `error`, `critical`:
```bash
DATASETS_VERBOSITY=error ./myprogram.py
```
All the methods of this logging module are documented below. The main ones are:
- [`logging.get_verbosity`] to get the current level of verbosity in the logger
- [`logging.set_verbosity`] to set the verbosity to the level of your choice
In order from the least to the most verbose (with their corresponding `int` values):
1. `logging.CRITICAL` or `logging.FATAL` (int value, 50): only report the most critical errors.
2. `logging.ERROR` (int value, 40): only report errors.
3. `logging.WARNING` or `logging.WARN` (int value, 30): only reports error and warnings. This the default level used by the library.
4. `logging.INFO` (int value, 20): reports error, warnings and basic information.
5. `logging.DEBUG` (int value, 10): report all information.

[[autodoc]] datasets.logging.set_verbosity

[[autodoc]] datasets.logging.set_verbosity_debug
[[autodoc]] datasets.logging.set_verbosity_error
[[autodoc]] datasets.logging.disable_propagation
[[autodoc]] datasets.logging.enable_propagation
## Configure progress bars
By default, `tqdm` progress bars will be displayed during dataset download and preprocessing. You can disable them globally by setting `HF_DATASETS_DISABLE_PROGRESS_BARS`
environment variable. You can also enable/disable them using [`~utils.enable_progress_bars`] and [`~utils.disable_progress_bars`]. If set, the environment variable has priority on the helpers.

# Metric Card for COMET
## Metric description
Crosslingual Optimized Metric for Evaluation of Translation (COMET) is an open-source framework used to train Machine Translation metrics that achieve high levels of correlation with different types of human judgments.
## How to use
COMET takes 3 lists of strings as input: `sources` (a list of source sentences), `predictions` (a list of candidate translations) and `references` (a list of reference translations).
```python
from datasets import load_metric
comet_metric = load_metric('comet')
source = ["Dem Feuer konnte Einhalt geboten werden", "Schulen und Kindergärten wurden eröffnet."]
hypothesis = ["The fire could be stopped", "Schools and kindergartens were open"]
reference = ["They were able to control the fire.", "Schools and kindergartens opened"]
comet_score = comet_metric.compute(predictions=hypothesis, references=reference, sources=source)
```
It has several configurations, named after the COMET model to be used. It will default to `wmt20-comet-da` (previously known as `wmt-large-da-estimator-1719`). Alternate models that can be chosen include `wmt20-comet-qe-da`, `wmt21-comet-mqm`, `wmt21-cometinho-da`, `wmt21-comet-qe-mqm` and `emnlp20-comet-rank`.
It also has several optional arguments:
`gpus`: optional, an integer (number of GPUs to train on) or a list of integers (which GPUs to train on). Set to 0 to use CPU. The default value is `None` (uses one GPU if possible, else use CPU).
`progress_bar`a boolean -- if set to `True`, progress updates will be printed out. The default value is `False`.
More information about model characteristics can be found on the [COMET website](https://unbabel.github.io/COMET/html/models.html).
## Output values
The COMET metric outputs two lists:
`scores`: a list of COMET scores for each of the input sentences, ranging from 0-1.
`mean_score`: the mean value of COMET scores `scores` over all the input sentences, ranging from 0-1.
### Values from popular papers
The [original COMET paper](https://arxiv.org/pdf/2009.09025.pdf) reported average COMET scores ranging from 0.4 to 0.6, depending on the language pairs used for evaluating translation models. They also illustrate that COMET correlates well with human judgements compared to other metrics such as [BLEU](https://huggingface.co/metrics/bleu) and [CHRF](https://huggingface.co/metrics/chrf).
## Examples
Full match:
```python
from datasets import load_metric
comet_metric = load_metric('comet')
source = ["Dem Feuer konnte Einhalt geboten werden", "Schulen und Kindergärten wurden eröffnet."]
hypothesis = ["They were able to control the fire.", "Schools and kindergartens opened"]
reference = ["They were able to control the fire.", "Schools and kindergartens opened"]
results = comet_metric.compute(predictions=hypothesis, references=reference, sources=source)
print([round(v, 1) for v in results["scores"]])
[1.0, 1.0]
```
Partial match:
```python
from datasets import load_metric
comet_metric = load_metric('comet')
source = ["Dem Feuer konnte Einhalt geboten werden", "Schulen und Kindergärten wurden eröffnet."]
hypothesis = ["The fire could be stopped", "Schools and kindergartens were open"]
reference = ["They were able to control the fire", "Schools and kindergartens opened"]
results = comet_metric.compute(predictions=hypothesis, references=reference, sources=source)
print([round(v, 2) for v in results["scores"]])
[0.19, 0.92]
```
No match:
```python
from datasets import load_metric
comet_metric = load_metric('comet')
source = ["Dem Feuer konnte Einhalt geboten werden", "Schulen und Kindergärten wurden eröffnet."]
hypothesis = ["The girl went for a walk", "The boy was sleeping"]
reference = ["They were able to control the fire", "Schools and kindergartens opened"]
results = comet_metric.compute(predictions=hypothesis, references=reference, sources=source)
print([round(v, 2) for v in results["scores"]])
[0.00, 0.00]
```
## Limitations and bias
The models provided for calculating the COMET metric are built on top of XLM-R and cover the following languages:
Afrikaans, Albanian, Amharic, Arabic, Armenian, Assamese, Azerbaijani, Basque, Belarusian, Bengali, Bengali Romanized, Bosnian, Breton, Bulgarian, Burmese, Burmese, Catalan, Chinese (Simplified), Chinese (Traditional), Croatian, Czech, Danish, Dutch, English, Esperanto, Estonian, Filipino, Finnish, French, Galician, Georgian, German, Greek, Gujarati, Hausa, Hebrew, Hindi, Hindi Romanized, Hungarian, Icelandic, Indonesian, Irish, Italian, Japanese, Javanese, Kannada, Kazakh, Khmer, Korean, Kurdish (Kurmanji), Kyrgyz, Lao, Latin, Latvian, Lithuanian, Macedonian, Malagasy, Malay, Malayalam, Marathi, Mongolian, Nepali, Norwegian, Oriya, Oromo, Pashto, Persian, Polish, Portuguese, Punjabi, Romanian, Russian, Sanskri, Scottish, Gaelic, Serbian, Sindhi, Sinhala, Slovak, Slovenian, Somali, Spanish, Sundanese, Swahili, Swedish, Tamil, Tamil Romanized, Telugu, Telugu Romanized, Thai, Turkish, Ukrainian, Urdu, Urdu Romanized, Uyghur, Uzbek, Vietnamese, Welsh, Western, Frisian, Xhosa, Yiddish.
Thus, results for language pairs containing uncovered languages are unreliable, as per the [COMET website](https://github.com/Unbabel/COMET)
Also, calculating the COMET metric involves downloading the model from which features are obtained -- the default model, `wmt20-comet-da`, takes over 1.79GB of storage space and downloading it can take a significant amount of time depending on the speed of your internet connection. If this is an issue, choose a smaller model; for instance `wmt21-cometinho-da` is 344MB.
