class Trainer:
"""
Trainer is a simple but feature-complete training and eval loop for PyTorch, optimized for 🤗 Transformers.
Args:
model ([`PreTrainedModel`] or `torch.nn.Module`, *optional*):
The model to train, evaluate or use for predictions. If not provided, a `model_init` must be passed.
<Tip>
[`Trainer`] is optimized to work with the [`PreTrainedModel`] provided by the library. You can still use
your own models defined as `torch.nn.Module` as long as they work the same way as the 🤗 Transformers
models.
</Tip>
args ([`TrainingArguments`], *optional*):
The arguments to tweak for training. Will default to a basic instance of [`TrainingArguments`] with the
`output_dir` set to a directory named *tmp_trainer* in the current directory if not provided.
data_collator (`DataCollator`, *optional*):
The function to use to form a batch from a list of elements of `train_dataset` or `eval_dataset`. Will
default to [`default_data_collator`] if no `processing_class` is provided, an instance of
[`DataCollatorWithPadding`] otherwise if the processing_class is a feature extractor or tokenizer.
train_dataset (Union[`torch.utils.data.Dataset`, `torch.utils.data.IterableDataset`, `datasets.Dataset`], *optional*):
The dataset to use for training. If it is a [`~datasets.Dataset`], columns not accepted by the
`model.forward()` method are automatically removed.
Note that if it's a `torch.utils.data.IterableDataset` with some randomization and you are training in a
distributed fashion, your iterable dataset should either use a internal attribute `generator` that is a
`torch.Generator` for the randomization that must be identical on all processes (and the Trainer will
manually set the seed of this `generator` at each epoch) or have a `set_epoch()` method that internally
sets the seed of the RNGs used.
eval_dataset (Union[`torch.utils.data.Dataset`, Dict[str, `torch.utils.data.Dataset`, `datasets.Dataset`]), *optional*):
The dataset to use for evaluation. If it is a [`~datasets.Dataset`], columns not accepted by the
`model.forward()` method are automatically removed. If it is a dictionary, it will evaluate on each
dataset prepending the dictionary key to the metric name.
processing_class (`PreTrainedTokenizerBase` or `BaseImageProcessor` or `FeatureExtractionMixin` or `ProcessorMixin`, *optional*):
Processing class used to process the data. If provided, will be used to automatically process the inputs
for the model, and it will be saved along the model to make it easier to rerun an interrupted training or
reuse the fine-tuned model.
This supercedes the `tokenizer` argument, which is now deprecated.
model_init (`Callable[[], PreTrainedModel]`, *optional*):
A function that instantiates the model to be used. If provided, each call to [`~Trainer.train`] will start
from a new instance of the model as given by this function.
The function may have zero argument, or a single one containing the optuna/Ray Tune/SigOpt trial object, to
be able to choose different architectures according to hyper parameters (such as layer count, sizes of
inner layers, dropout probabilities etc).
compute_loss_func (`Callable`, *optional*):
A function that accepts the raw model outputs, labels, and the number of items in the entire accumulated
batch (batch_size * gradient_accumulation_steps) and returns the loss. For example, see the default [loss function](https://github.com/huggingface/transformers/blob/052e652d6d53c2b26ffde87e039b723949a53493/src/transformers/trainer.py#L3618) used by [`Trainer`].
compute_metrics (`Callable[[EvalPrediction], Dict]`, *optional*):
The function that will be used to compute metrics at evaluation. Must take a [`EvalPrediction`] and return
a dictionary string to metric values. *Note* When passing TrainingArgs with `batch_eval_metrics` set to
`True`, your compute_metrics function must take a boolean `compute_result` argument. This will be triggered
after the last eval batch to signal that the function needs to calculate and return the global summary
statistics rather than accumulating the batch-level statistics
callbacks (List of [`TrainerCallback`], *optional*):
A list of callbacks to customize the training loop. Will add those to the list of default callbacks
detailed in [here](callback).
If you want to remove one of the default callbacks used, use the [`Trainer.remove_callback`] method.
optimizers (`Tuple[torch.optim.Optimizer, torch.optim.lr_scheduler.LambdaLR]`, *optional*, defaults to `(None, None)`):
A tuple containing the optimizer and the scheduler to use. Will default to an instance of [`AdamW`] on your
model and a scheduler given by [`get_linear_schedule_with_warmup`] controlled by `args`.
optimizer_cls_and_kwargs (`Tuple[Type[torch.optim.Optimizer], Dict[str, Any]]`, *optional*):
A tuple containing the optimizer class and keyword arguments to use.
Overrides `optim` and `optim_args` in `args`. Incompatible with the `optimizers` argument.
Unlike `optimizers`, this argument avoids the need to place model parameters on the correct devices before initializing the Trainer.
preprocess_logits_for_metrics (`Callable[[torch.Tensor, torch.Tensor], torch.Tensor]`, *optional*):
A function that preprocess the logits right before caching them at each evaluation step. Must take two
tensors, the logits and the labels, and return the logits once processed as desired. The modifications made
by this function will be reflected in the predictions received by `compute_metrics`.
Note that the labels (second parameter) will be `None` if the dataset does not have them.
Important attributes:
- **model** -- Always points to the core model. If using a transformers model, it will be a [`PreTrainedModel`]
subclass.
- **model_wrapped** -- Always points to the most external model in case one or more other modules wrap the
original model. This is the model that should be used for the forward pass. For example, under `DeepSpeed`,
the inner model is wrapped in `DeepSpeed` and then again in `torch.nn.DistributedDataParallel`. If the inner
model hasn't been wrapped, then `self.model_wrapped` is the same as `self.model`.
- **is_model_parallel** -- Whether or not a model has been switched to a model parallel mode (different from
data parallelism, this means some of the model layers are split on different GPUs).
- **place_model_on_device** -- Whether or not to automatically place the model on the device - it will be set
to `False` if model parallel or deepspeed is used, or if the default
`TrainingArguments.place_model_on_device` is overridden to return `False` .
- **is_in_train** -- Whether or not a model is currently running `train` (e.g. when `evaluate` is called while
in `train`)

"""
Launch an hyperparameter search using `optuna` or `Ray Tune` or `SigOpt`. The optimized quantity is determined
by `compute_objective`, which defaults to a function returning the evaluation loss when no metric is provided,
the sum of all metrics otherwise.
<Tip warning={true}>
To use this method, you need to have provided a `model_init` when initializing your [`Trainer`]: we need to
reinitialize the model at each new run. This is incompatible with the `optimizers` argument, so you need to
subclass [`Trainer`] and override the method [`~Trainer.create_optimizer_and_scheduler`] for custom
optimizer/scheduler.
</Tip>
Args:
hp_space (`Callable[["optuna.Trial"], Dict[str, float]]`, *optional*):
A function that defines the hyperparameter search space. Will default to
[`~trainer_utils.default_hp_space_optuna`] or [`~trainer_utils.default_hp_space_ray`] or
[`~trainer_utils.default_hp_space_sigopt`] depending on your backend.
compute_objective (`Callable[[Dict[str, float]], float]`, *optional*):
A function computing the objective to minimize or maximize from the metrics returned by the `evaluate`
method. Will default to [`~trainer_utils.default_compute_objective`].
n_trials (`int`, *optional*, defaults to 100):
The number of trial runs to test.
direction (`str` or `List[str]`, *optional*, defaults to `"minimize"`):
If it's single objective optimization, direction is `str`, can be `"minimize"` or `"maximize"`, you
should pick `"minimize"` when optimizing the validation loss, `"maximize"` when optimizing one or
several metrics. If it's multi objectives optimization, direction is `List[str]`, can be List of

backend (`str` or [`~training_utils.HPSearchBackend`], *optional*):
The backend to use for hyperparameter search. Will default to optuna or Ray Tune or SigOpt, depending
on which one is installed. If all are installed, will default to optuna.
hp_name (`Callable[["optuna.Trial"], str]]`, *optional*):
A function that defines the trial/run name. Will default to None.
kwargs (`Dict[str, Any]`, *optional*):
Additional keyword arguments for each backend:
- `optuna`: parameters from
[optuna.study.create_study](https://optuna.readthedocs.io/en/stable/reference/generated/optuna.study.create_study.html)
and also the parameters `timeout`, `n_jobs` and `gc_after_trial` from
[optuna.study.Study.optimize](https://optuna.readthedocs.io/en/stable/reference/generated/optuna.study.Study.html#optuna.study.Study.optimize)
- `ray`: parameters from [tune.run](https://docs.ray.io/en/latest/tune/api_docs/execution.html#tune-run).
If `resources_per_trial` is not set in the `kwargs`, it defaults to 1 CPU core and 1 GPU (if available).
If `progress_reporter` is not set in the `kwargs`,
[ray.tune.CLIReporter](https://docs.ray.io/en/latest/tune/api/doc/ray.tune.CLIReporter.html) is used.
- `sigopt`: the parameter `proxies` from
[sigopt.Connection.set_proxies](https://docs.sigopt.com/support/faq#how-do-i-use-sigopt-with-a-proxy).

Run evaluation and returns metrics.

If you pass a dictionary with names of datasets as keys and datasets as values, evaluate will run
separate evaluations on each dataset. This can be useful to monitor how training affects other
datasets or simply to get a more fine-grained evaluation.
When used with `load_best_model_at_end`, make sure `metric_for_best_model` references exactly one
of the datasets. If you, for example, pass in `{"data1": data1, "data2": data2}` for two datasets
`data1` and `data2`, you could specify `metric_for_best_model="eval_data1_loss"` for using the

"""
Because of inconsistencies introduced between CUDA versions, the checks here are less strict. SuperGlue relies
on SuperPoint, which may, depending on CUDA version, return different number of keypoints (866 or 867 in this
specific test example). The consequence of having different number of keypoints is that the number of matches
will also be different. In the 20 first matches being checked, having one keypoint less will result in 1 less
match. The matching scores will also be different, as the keypoints are different. The checks here are less
strict to account for these inconsistencies.
Therefore, the test checks that the predicted number of matches, matches and matching scores are close to the

" Wednesday, a step that gives the court jurisdiction over alleged crimes in Palestinian territories. The"
" formal accession was marked with a ceremony at The Hague, in the Netherlands, where the court is based."
" The Palestinians signed the ICC's founding Rome Statute in January, when they also accepted its"
' jurisdiction over alleged crimes committed "in the occupied Palestinian territory, including East'
' Jerusalem, since June 13, 2014." Later that month, the ICC opened a preliminary examination into the'
" situation in Palestinian territories, paving the way for possible war crimes investigations against"
" Israelis. As members of the court, Palestinians may be subject to counter-charges as well. Israel and"
" the United States, neither of which is an ICC member, opposed the Palestinians' efforts to join the"
" body. But Palestinian Foreign Minister Riad al-Malki, speaking at Wednesday's ceremony, said it was a"
' move toward greater justice. "As Palestine formally becomes a State Party to the Rome Statute today, the'
' world is also a step closer to ending a long era of impunity and injustice," he said, according to an'
' ICC news release. "Indeed, today brings us closer to our shared goals of justice and peace." Judge'
" Kuniko Ozaki, a vice president of the ICC, said acceding to the treaty was just the first step for the"
' Palestinians. "As the Rome Statute today enters into force for the State of Palestine, Palestine'
" acquires all the rights as well as responsibilities that come with being a State Party to the Statute."
' These are substantive commitments, which cannot be taken lightly," she said. Rights group Human Rights'
' Watch welcomed the development. "Governments seeking to penalize Palestine for joining the ICC should'
" immediately end their pressure, and countries that support universal acceptance of the court's treaty"
' should speak out to welcome its membership," said Balkees Jarrah, international justice counsel for the'
" group. \"What's objectionable is the attempts to undermine international justice, not Palestine's"
' decision to join a treaty to which over 100 countries around the world are members." In January, when'
" the preliminary ICC examination was opened, Israeli Prime Minister Benjamin Netanyahu described it as an"
' outrage, saying the court was overstepping its boundaries. The United States also said it "strongly"'
" disagreed with the court's decision. \"As we have said repeatedly, we do not believe that Palestine is a"
' state and therefore we do not believe that it is eligible to join the ICC," the State Department said in'
' a statement. It urged the warring sides to resolve their differences through direct negotiations. "We'
' will continue to oppose actions against Israel at the ICC as counterproductive to the cause of peace,"'
" it said. But the ICC begs to differ with the definition of a state for its purposes and refers to the"
' territories as "Palestine." While a preliminary examination is not a formal investigation, it allows the'
" court to review evidence and determine whether to investigate suspects on both sides. Prosecutor Fatou"
' Bensouda said her office would "conduct its analysis in full independence and impartiality." The war'
" between Israel and Hamas militants in Gaza last summer left more than 2,000 people dead. The inquiry"
" will include alleged war crimes committed since June. The International Criminal Court was set up in"
" 2002 to prosecute genocide, crimes against humanity and war crimes. CNN's Vasco Cotovio, Kareem Khadder"
" and Faith Karimi contributed to this report."

# Multi Adapter RL (MARL) - a single base model for everything
Here we present an approach that uses a single base model for the entire PPO algorithm - which includes retrieving the reference logits, computing the active logits and the rewards. This feature is experimental as we did not test the convergence of the approach. We encourage the community to let us know if they potentially face issues.
## Requirements
You just need to install `peft` and optionally install `bitsandbytes` as well if you want to go for 8bit base models, for more memory efficient finetuning.
## Summary
You need to address this approach in three stages that we summarize as follows:
1- Train a base model on the target domain (e.g. [IMDB dataset](https://huggingface.co/datasets/stanfordnlp/imdb)) - this is the Supervised Fine Tuning stage - it can leverage the `SFTTrainer` from TRL.
2- Train a reward model using `peft`. This is required in order to re-use the adapter during the RL optimisation process (step 3 below). We show an example of leveraging the `RewardTrainer` from TRL in [this example](https://github.com/huggingface/trl/tree/main/examples/scripts/reward_modeling.py)
3- Fine tune new adapters on the base model using PPO and the reward adapter. ("0 abstraction RL")
Make sure to use the same model (i.e. same architecture and same weights) for the stages 2 & 3.
## Quickstart
Let us assume you have trained your reward adapter on `llama-7b` model using `RewardTrainer` and pushed the weights on the hub under `trl-lib/llama-7b-hh-rm-adapter`.
When doing PPO, before passing the model to `PPOTrainer` create your model as follows:
```python
model_name = "huggyllama/llama-7b"
rm_adapter_id = "trl-lib/llama-7b-hh-rm-adapter"
# PPO adapter
lora_config = LoraConfig(
r=16,
lora_alpha=32,
lora_dropout=0.05,
bias="none",
task_type="CAUSAL_LM",
)
model = AutoModelForCausalLMWithValueHead.from_pretrained(
model_name,
peft_config=lora_config,
reward_adapter=rm_adapter_id,
)
...
trainer = PPOTrainer(
model=model,
...
)
...
```
Then inside your PPO training loop, call the `compute_reward_score` method by accessing the `model` attribute from `PPOTrainer`.
```python
rewards = trainer.model.compute_reward_score(**inputs)
```
## Advanced usage
### Control on the adapter name
If you are familiar with the `peft` library, you know that you can use multiple adapters inside the same model. What you can do is train multiple adapters on the same base model to fine-tune on different policies.
In this case, you want to be able to control the adapter name you want to activate back, after retrieving the reward. For that, simply pass the appropriate `adapter_name` to `ppo_adapter_name` argument when calling `compute_reward_score`.
```python
adapter_name_policy_1 = "policy_1"
rewards = trainer.model.compute_reward_score(**inputs, ppo_adapter_name=adapter_name_policy_1)
...
```
### Using 4-bit and 8-bit base models
For more memory efficient fine-tuning, you can load your base model in 8-bit or 4-bit while keeping the adapters in the default precision (float32).
Just pass the appropriate arguments (i.e. `load_in_8bit=True` or `load_in_4bit=True`) to `AutoModelForCausalLMWithValueHead.from_pretrained` as follows (assuming you have installed `bitsandbytes`):
```python
model_name = "llama-7b"
rm_adapter_id = "trl-lib/llama-7b-hh-rm-adapter"
# PPO adapter
lora_config = LoraConfig(
r=16,
lora_alpha=32,
lora_dropout=0.05,
bias="none",
task_type="CAUSAL_LM",
)
model = AutoModelForCausalLMWithValueHead.from_pretrained(
model_name,
peft_config=lora_config,
reward_adapter=rm_adapter_id,
load_in_8bit=True,
)
...
trainer = PPOTrainer(
model=model,
...
)
...

# PRM800K Dataset
## Summary
The PRM800K dataset is a processed version of [OpenAI's PRM800K](https://github.com/openai/prm800k), designed to train models using the [TRL library](https://github.com/huggingface/trl) for stepwise supervision tasks. It contains 800,000 step-level correctness labels for model-generated solutions to problems from the MATH dataset. This dataset enables models to learn and verify each step of a solution, enhancing their reasoning capabilities.
## Data Structure
- **Format**: [Standard](https://huggingface.co/docs/trl/main/dataset_formats#standard)
- **Type**: [Stepwise supervision](https://huggingface.co/docs/trl/main/dataset_formats#stepwise-supervision)
Columns:
- `"prompt"`: The problem statement.
- `"completions"`: A list of reasoning steps generated to solve the problem.
- `"labels"`: A list of booleans or floats indicating the correctness of each corresponding reasoning step.
This structure allows models to learn the correctness of each step in a solution, facilitating improved reasoning and problem-solving abilities.
## Generation script
The script used to generate this dataset can be found [here](https://github.com/huggingface/trl/blob/main/examples/datasets/prm800k.py).

# DPO pipeline for the creation of StackLlaMa 2: a Stack exchange llama-v2-7b model
## Prerequisites
Install all the dependencies in the `requirements.txt`:
```
$ pip install -U -r requirements.txt
```
Since we will use `accelerate` for training, make sure to run:
```
$ accelerate config
```
## Training
There were two main steps to the DPO training process:
1. Supervised fine-tuning of the base llama-v2-7b model to create llama-v2-7b-se:
```
accelerate launch examples/research_projects/stack_llama_2/scripts/sft_llama2.py \
--output_dir="./sft" \
--max_steps=500 \
--logging_steps=10 \
--save_steps=10 \
--per_device_train_batch_size=4 \
--per_device_eval_batch_size=1 \
--gradient_accumulation_steps=2 \
--gradient_checkpointing=False \
--group_by_length=False \
--learning_rate=1e-4 \
--lr_scheduler_type="cosine" \
--warmup_steps=100 \
--weight_decay=0.05 \
--optim="paged_adamw_32bit" \
--bf16=True \
--remove_unused_columns=False \
--run_name="sft_llama2" \
--report_to="wandb"
```
1. Run the DPO trainer using the model saved by the previous step:
```
accelerate launch examples/research_projects/stack_llama_2/scripts/dpo_llama2.py \
--model_name_or_path="sft/final_checkpoint" \
--output_dir="dpo"
```
## Merging the adaptors
To merge the adaptors into the base model we can use the `merge_peft_adapter.py` helper script that comes with TRL:
```
python examples/research_projects/stack_llama/scripts/merge_peft_adapter.py --base_model_name="meta-llama/Llama-2-7b-hf" --adapter_model_name="dpo/final_checkpoint/" --output_name="stack-llama-2"
```
which will also push the model to your HuggingFace hub account.
## Running the model
We can load the DPO-trained LoRA adaptors which were saved by the DPO training step and load them via:
```py
from peft import AutoPeftModelForCausalLM
model = AutoPeftModelForCausalLM.from_pretrained(
"dpo/final_checkpoint",
low_cpu_mem_usage=True,
torch_dtype=torch.float16,
load_in_4bit=True,
)
model.generate(...)
```

# Launching Accelerate scripts
In the previous tutorial, you were introduced to how to modify your current training script to use Accelerate.
The final version of that code is shown below:
```python
from accelerate import Accelerator
accelerator = Accelerator()
model, optimizer, training_dataloader, scheduler = accelerator.prepare(
model, optimizer, training_dataloader, scheduler
)
for batch in training_dataloader:
optimizer.zero_grad()
inputs, targets = batch
outputs = model(inputs)
loss = loss_function(outputs, targets)
accelerator.backward(loss)
optimizer.step()
scheduler.step()
```
But how do you run this code and have it utilize the special hardware available to it?
First, you should rewrite the above code into a function, and make it callable as a script. For example:
```diff
from accelerate import Accelerator
+ def main():
accelerator = Accelerator()
model, optimizer, training_dataloader, scheduler = accelerator.prepare(
model, optimizer, training_dataloader, scheduler
)
for batch in training_dataloader:
optimizer.zero_grad()
inputs, targets = batch
outputs = model(inputs)
loss = loss_function(outputs, targets)
accelerator.backward(loss)
optimizer.step()
scheduler.step()
+ if __name__ == "__main__":
+ main()
```
Next, you need to launch it with `accelerate launch`.
<Tip warning={true}>
It's recommended you run `accelerate config` before using `accelerate launch` to configure your environment to your liking.
Otherwise Accelerate will use very basic defaults depending on your system setup.
</Tip>
## Using accelerate launch
Accelerate has a special CLI command to help you launch your code in your system through `accelerate launch`.
This command wraps around all of the different commands needed to launch your script on various platforms, without you having to remember what each of them is.
<Tip>
If you are familiar with launching scripts in PyTorch yourself such as with `torchrun`, you can still do this. It is not required to use `accelerate launch`.
</Tip>
You can launch your script quickly by using:
```bash
accelerate launch {script_name.py} --arg1 --arg2 ...
```
Just put `accelerate launch` at the start of your command, and pass in additional arguments and parameters to your script afterward like normal!
Since this runs the various torch spawn methods, all of the expected environment variables can be modified here as well.
For example, here is how to use `accelerate launch` with a single GPU:
```bash
# for cuda device:
CUDA_VISIBLE_DEVICES="0" accelerate launch {script_name.py} --arg1 --arg2 ...
# for xpu device:
ZE_AFFINITY_MASK="0" accelerate launch {script_name.py} --arg1 --arg2 ...
```
You can also use `accelerate launch` without performing `accelerate config` first, but you may need to manually pass in the right configuration parameters.
In this case, Accelerate will make some hyperparameter decisions for you, e.g., if GPUs are available, it will use all of them by default without the mixed precision.
Here is how you would use all GPUs and train with mixed precision disabled:
```bash
accelerate launch --multi_gpu {script_name.py} {--arg1} {--arg2} ...
```
Or by specifying a number of GPUs to use:
```bash
accelerate launch --num_processes=2 {script_name.py} {--arg1} {--arg2} ...
```
To get more specific you should pass in the needed parameters yourself. For instance, here is how you
would also launch that same script on two GPUs using mixed precision while avoiding all of the warnings:
```bash
accelerate launch --multi_gpu --mixed_precision=fp16 --num_processes=2 {script_name.py} {--arg1} {--arg2} ...
```
For a complete list of parameters you can pass in, run:
```bash
accelerate launch -h
```
<Tip>
Even if you are not using Accelerate in your code, you can still use the launcher for starting your scripts!
</Tip>
For a visualization of this difference, that earlier `accelerate launch` on multi-gpu would look something like so with `torchrun`:
```bash
MIXED_PRECISION="fp16" torchrun --nproc_per_node=2 --nnodes=1 {script_name.py} {--arg1} {--arg2} ...
```
You can also launch your script utilizing the launch CLI as a python module itself, enabling the ability to pass in other python-specific
launching behaviors. To do so, use `accelerate.commands.launch` instead of `accelerate launch`:
```bash
python -m accelerate.commands.launch --num_processes=2 {script_name.py} {--arg1} {--arg2}
```
If you want to execute the script with any other python flags, you can pass them in as well similar to `-m`, such as
the below example enabling unbuffered stdout and stderr:
```bash
python -u -m accelerate.commands.launch --num_processes=2 {script_name.py} {--arg1} {--arg2}
```
<Tip>
You can run your code on CPU as well! This is helpful for debugging and testing purposes on toy models and datasets.
```bash
accelerate launch --cpu {script_name.py} {--arg1} {--arg2}
```
</Tip>
## Why you should always use `accelerate config`
Why is it useful to the point you should **always** run `accelerate config`?
Remember that earlier call to `accelerate launch` as well as `torchrun`?
Post configuration, to run that script with the needed parts you just need to use `accelerate launch` outright, without passing anything else in:
```bash
accelerate launch {script_name.py} {--arg1} {--arg2} ...
```
## Custom Configurations
As briefly mentioned earlier, `accelerate launch` should be mostly used through combining set configurations
made with the `accelerate config` command. These configs are saved to a `default_config.yaml` file in your cache folder for Accelerate.
This cache folder is located at (with decreasing order of priority):
- The content of your environment variable `HF_HOME` suffixed with `accelerate`.
- If it does not exist, the content of your environment variable `XDG_CACHE_HOME` suffixed with
`huggingface/accelerate`.
- If this does not exist either, the folder `~/.cache/huggingface/accelerate`.
To have multiple configurations, the flag `--config_file` can be passed to the `accelerate launch` command paired
with the location of the custom yaml.
An example yaml may look something like the following for two GPUs on a single machine using `fp16` for mixed precision:
```yaml
compute_environment: LOCAL_MACHINE
deepspeed_config: {}
distributed_type: MULTI_GPU
fsdp_config: {}
machine_rank: 0
main_process_ip: null
main_process_port: null
main_training_function: main
mixed_precision: fp16
num_machines: 1
num_processes: 2
use_cpu: false
```
Launching a script from the location of that custom yaml file looks like the following:
```bash
accelerate launch --config_file {path/to/config/my_config_file.yaml} {script_name.py} {--arg1} {--arg2} ...
```
## Multi-node training
Multi-node training with Accelerate is similar to [multi-node training with torchrun](https://pytorch.org/tutorials/intermediate/ddp_series_multinode.html). The simplest way to launch a multi-node training run is to do the following:
- Copy your codebase and data to all nodes. (or place them on a shared filesystem)
- Setup your python packages on all nodes.
- Run `accelerate config` on the main single node first. After specifying the number of nodes, you will be asked to specify the rank of each node (this will be 0 for the main/master node), along with the IP address and port for the main process. This is required for the worker nodes to communicate with the main process. Afterwards, you can copy or send this config file across all of your nodes, changing the `machine_rank` to 1, 2,3, etc. to avoid having to run the command (or just follow their directions directly for launching with `torchrun` as well)
Once you have done this, you can start your multi-node training run by running `accelerate launch` (or `torchrun`) on all nodes.
<Tip>
It is required that the command be ran on all nodes for everything to start, not just running it from the main node. You can use something like SLURM or a different process executor to wrap around this requirement and call everything from a single command.
</Tip>
<Tip>
It is recommended to use the intranet IP of your main node over the public IP for better latency. This is the `192.168.x.x` or the `172.x.x.x` address you see when you run `hostname -I` on the main node.
</Tip>
To get a better idea about multi-node training, check out our example for [multi-node training with FSDP](https://huggingface.co/blog/ram-efficient-pytorch-fsdp).

# Accelerated PyTorch Training on Mac
With PyTorch v1.12 release, developers and researchers can take advantage of Apple silicon GPUs for significantly faster model training.
This unlocks the ability to perform machine learning workflows like prototyping and fine-tuning locally, right on Mac.
Apple's Metal Performance Shaders (MPS) as a backend for PyTorch enables this and can be used via the new `"mps"` device.
This will map computational graphs and primitives on the MPS Graph framework and tuned kernels provided by MPS.
For more information please refer official documents [Introducing Accelerated PyTorch Training on Mac](https://pytorch.org/blog/introducing-accelerated-pytorch-training-on-mac/)
and [MPS BACKEND](https://pytorch.org/docs/stable/notes/mps.html).
### Benefits of Training and Inference using Apple Silicon Chips
1. Enables users to train larger networks or batch sizes locally
2. Reduces data retrieval latency and provides the GPU with direct access to the full memory store due to unified memory architecture.
Therefore, improving end-to-end performance.
3. Reduces costs associated with cloud-based development or the need for additional local GPUs.
**Pre-requisites**: To install torch with mps support,
please follow this nice medium article [GPU-Acceleration Comes to PyTorch on M1 Macs](https://medium.com/towards-data-science/gpu-acceleration-comes-to-pytorch-on-m1-macs-195c399efcc1).
## How it works out of the box
It is enabled by default on MacOs machines with MPS enabled Apple Silicon GPUs.
To disable it, pass `--cpu` flag to `accelerate launch` command or answer the corresponding question when answering the `accelerate config` questionnaire.
You can directly run the following script to test it out on MPS enabled Apple Silicon machines:
```bash
accelerate launch /examples/cv_example.py --data_dir images
```
## A few caveats to be aware of
1. Distributed setups `gloo` and `nccl` are not working with `mps` device.
This means that currently only single GPU of `mps` device type can be used.
Finally, please, remember that, `Accelerate` only integrates MPS backend, therefore if you
have any problems or questions with regards to MPS backend usage, please, file an issue with [PyTorch GitHub](https://github.com/pytorch/pytorch/issues). | accelerate/docs/source/usage_guides/mps.md/0 | {

# This example trains a SmolLM base model on WikiText-2 v1
# in any of the following settings (with the same script):
# - single CPU or single GPU
# - multi GPUS (using PyTorch distributed mode)
# - (multi) TPUs
# - fp16 (mixed-precision) or fp32 (normal precision)
#
# To run it in each of these various modes, follow the instructions

# candle-based
Experimental, not instruction-tuned small LLM from the Hazy Research group, combining local and linear attention layers.
[Blogpost](https://hazyresearch.stanford.edu/blog/2024-03-03-based)
[Simple linear attention language models balance the recall-throughput tradeoff](https://arxiv.org/abs/2402.18668)
## Running an example
```bash
$ cargo run --example based --release -- --prompt "Flying monkeys are" --which 1b-50b --sample-len 100
Flying monkeys are a common sight in the wild, but they are also a threat to humans.
The new study, published today (July 31) in the journal Science Advances, shows that the monkeys are using their brains to solve the problem of how to get around the problem.
"We found that the monkeys were using a strategy called 'cognitive mapping' - they would use their brains to map out the route ahead," says lead author Dr. David J. Smith from the University of California

# candle-mamba: Mamba implementation
Candle implementation of *Mamba* [1] inference only. Mamba is an alternative to
the transformer architecture. It leverages State Space Models (SSMs) with the
goal of being computationally efficient on long sequences. The implementation is
based on [mamba.rs](https://github.com/LaurentMazare/mamba.rs).
- [1]. [Mamba: Linear-Time Sequence Modeling with Selective State Spaces](https://arxiv.org/abs/2312.00752).
Compared to the mamba-minimal example, this version is far more efficient but
would only work for inference.
## Running the example
```bash
$ cargo run --example mamba-minimal --release -- --prompt "Mamba is the"

# candle-quantized-llama: Fast Inference of quantized LLaMA models
This example provides a quantized LLaMA model similar to
[llama.cpp](https://github.com/ggerganov/llama.cpp). This is based on candle
built-in quantization methods. Supported features include:
- 2-bit, 3-bit, 4-bit, 5-bit, 6-bit and 8-bit integer quantization support.
- SIMD optimizations on Apple Silicon and x86.
- Support using the `gguf` and `ggml` file formats.
The weights are automatically downloaded for you from the [HuggingFace
Hub](https://huggingface.co/) on the first run. There are various command line
flags to use local files instead, run with `--help` to learn about them.
## Running some example.
```bash
cargo run --example quantized --release -- --prompt "The best thing about coding in rust is "
> avx: true, neon: false, simd128: false, f16c: true
> temp: 0.80 repeat-penalty: 1.10 repeat-last-n: 64
> loaded 291 tensors (3.79GB) in 2.17s
> params: HParams { n_vocab: 32000, n_embd: 4096, n_mult: 256, n_head: 32, n_layer: 32, n_rot: 128, ftype: 2 }
> The best thing about coding in rust is 1.) that I don’t need to worry about memory leaks, 2.) speed and 3.) my program will compile even on old machines.
```
Using the mixtral sparse mixture of expert model:
```bash
$ cargo run --example quantized --release -- --which mixtral --prompt "Lebesgue's integral is superior to Riemann's because "
> avx: true, neon: false, simd128: false, f16c: true

Lebesgue's integral is superior to Riemann's because 1. it is defined for a wider class of functions, those which are absolutely integrable; 2. the definition does not involve limits in two variables---one being computed before the other (which makes some computations more difficult); and 3. interchange of order of integration is easier to establish than with Riemann's integral. On the other hand, Lebesgue's integral applies only for bounded functions defined on finite intervals; it does not provide numerical values for improper integrals. The latter are best evaluated using Cauchy's limit definition.
The reason $f(x) = x^2$ is discontinuous at the ends of its interval of definition, and Riemann's integral requires continuity on the whole of an open interval containing it (see our earlier post), sine no such function exists with this property, is that the endpoints are infinite in measure for Lebesgue's integral.
```
## Command-line flags
Run with `--help` to see all options.
- `--which`: specify the model to use, e.g. `7b`, `13-chat`, `7b-code`.
- `--prompt interactive`: interactive mode where multiple prompts can be
entered.
- `--model mymodelfile.gguf`: use a local model file rather than getting one
from the hub.

## SigLIP
SigLIP is multi-modal text-vision model that improves over CLIP by using a sigmoid based loss,
[HuggingFace](https://huggingface.co/google/siglip-base-patch16-224).
### Running an example
```
$ cargo run --features cuda -r --example siglip -
