[ "Hi @Mehrad0711,\r\n\r\nI'm afraid there is no \"canonical\" Hugging Face dataset named \"few-nerd\".\r\n\r\nThere are 2 kinds of datasets hosted at the Hugging Face Hub:\r\n- canonical datasets (their identifier contains no slash \"/\"): we, the Hugging Face team, supervise their implementation and we make sure they work correctly by means of our test suite\r\n- community datasets (their identifier contains a slash \"/\", where before the slash it is the username or the organization name): those datasets are uploaded to the Hub by the community, and we, the Hugging Face team, do not supervise them; it is the responsibility of the user/organization implementing them properly if they want them to be used by other users.\r\n\r\nIn this specific case, there is no \"canonical\" dataset named \"few-nerd\". On the other hand, there are two \"community\" datasets named \"few-nerd\":\r\n- [\"nbroad/few-nerd\"](https://huggingface.co/datasets/nbroad/few-nerd)\r\n- [\"dfki-nlp/few-nerd\"](https://huggingface.co/datasets/dfki-nlp/few-nerd)\r\n\r\nIf they were properly implemented, you should be able to load them this way:\r\n```python\r\n# \"nbroad/few-nerd\" community dataset\r\nds = load_dataset(\"nbroad/few-nerd\", \"supervised\")\r\n\r\n# \"dfki-nlp/few-nerd\" community dataset\r\nds = load_dataset(\"dfki-nlp/few-nerd\", \"supervised\")\r\n```\r\n\r\nHowever, they are not correctly implemented and both of them give errors:\r\n- \"nbroad/few-nerd\":\r\n ```\r\n TypeError: expected str, bytes or os.PathLike object, not dict\r\n ```\r\n- \"dfki-nlp/few-nerd\":\r\n ```\r\n ConnectionError: Couldn't reach https://cloud.tsinghua.edu.cn/f/09265750ae6340429827/?dl=1\r\n ```\r\n\r\nYou could try to contact their users/organizations to inform them about their bugs and ask them if they are planning to fix them. Alternatively you could try to implement your own script for this dataset.", "Thanks @albertvillanova for your detailed explanation! I will resort to my own scripts for now. ", "Hello, @Mehrad0711; Hi, @albertvillanova !\r\nI am the maintainer of the `dfki/few-nerd\" dataset script, sorry for the very late reply and hope this message finds you well!\r\nWe should use\r\n```\r\ndataset = load_dataset(\"dfki-nlp/few-nerd\", name=\"supervised\")\r\n```\r\ninstead of not specifying the \"name\" argument, where name is from `[\"supervised\", \"inter\", \"intra\"]`. Otherwise the method just treats \"supervised\" as `split`, which we reserve after specifying the name, since for each name, there are three splits: train, dev and test.\r\n\r\nAlso we use Tsinghua server source to download data files since it is the official source referred in the paper where the dataset is released (even though it is cc-by-sa-4.0 licensed, means we can copy the data anywhere after mentioning the license\r\n). Sometimes the server just runs down due to high pressure, kinda weird (we encountered the same server problem serveral times a month when we conducted experiments on Few-NERD XD). I tried the script just now and it works perfectly!\r\n```\r\n>> dataset\r\nDatasetDict({\r\n train: Dataset({\r\n features: ['id', 'tokens', 'ner_tags', 'fine_ner_tags'],\r\n num_rows: 131767\r\n })\r\n validation: Dataset({\r\n features: ['id', 'tokens', 'ner_tags', 'fine_ner_tags'],\r\n num_rows: 18824\r\n })\r\n test: Dataset({\r\n features: ['id', 'tokens', 'ner_tags', 'fine_ner_tags'],\r\n num_rows: 37648\r\n })\r\n})\r\n>>> dataset[\"train\"]\r\nDataset({\r\n features: ['id', 'tokens', 'ner_tags', 'fine_ner_tags'],\r\n num_rows: 131767\r\n})\r\n>>> dataset[\"train\"][0]\r\n{'id': '0', 'tokens': ['Paul', 'International', 'airport', '.'], 'ner_tags': [0, 0, 0, 0], 'fine_ner_tags': [0, 0, 0, 0]}\r\n```\r\nAnyways if you cannot stand the pain with the server and its slow download speed, you can also download the `dfki/few-nerd.py` script from HF and change the `_URLs` to your personal drive (after you once successfully download the data and upload to your cloud drive), and then load the .py script locally.\r\n\r\nHope this reply can still be any help.

IMO it makes the most sense to yield one example for each person (so the total of 24 examples), so the features dict should be similar to this:\r\n \r\n ```python\r\n features = Features({\r\n \"rgb\": Sequence(Image()), # for the png frames\r\n \"rgb_cal\": {\"intrisic_mat\": Array2D(shape=(3, 3), dtype=\"float32\"), \"extrinsic_mat\": {\"rotation\": Array2D(shape=(3, 3), dtype=\"float32\"), \"translation\": Sequence(Value(\"float32\", length=3)}},\r\n \"depth\": Sequence(Value(\"string\")), # for the depth frames\r\n \"depth_cal\": the same as \"rgb_cal\",\r\n \"head_pose_gt\": Sequence({\"center\": Sequence(Value(\"float32\", length=3), \"rotation\": Array2D(shape=(3, 3), dtype=\"float32\")}),\r\n \"head_template\": Value(\"string\"), # for the person's obj file\r\n\r\n })\r\n ```\r\n We can add a \"Data Processing\" section to the card to explain how to parse the files.\r\n\r\n\r\n2. Yes, it's ok to parse the files as long as it doesn't take too much time/memory (e.g., it's ok to parse the `*_pose.txt` or `*.cal` files, but it's better to leave the `*_depth.bin` or `*.obj` files unprocessed and yield the paths to them)", "Thanks for the suggestions @mariosasko, yielding one example for each person would make things much easier.\r\nOkay.

How about this:\r\n\r\n`config.IN_MEMORY_MAX_SIZE` (or whatever the final env var will be minus `HF_DATASETS_` prefix).\r\n\r\nThis is of course just my opinion.\r\n\r\n", "Thanks for the comment :)\r\nI like both propositions, and I agree this would be better in order to allow support for 1M, 1T etc. \r\nRegarding the prefix of the variable in config.py I don't have a strong opinion.

This is an optimization that benefits only select users and is a burden on the rest.\r\n\r\nIn my line of dev/debug work (multiple short runs that have to be very fast) now I have to remember to disable this feature explicitly on every machine I work :(\r\n", "Having the dataset in memory is nice to get the speed but I agree that the lack of caching for dataset in memory is an issue. By default we always had caching on.\r\nHere the issue is that in-memory datasets are still not able to use the cache - we should fix this asap IMO.\r\n\r\nHere is the PR that fixes this: https://github.com/huggingface/datasets/pull/2329", "But why do they have to be datasets in memory in the first place? Why not just have the default that all datasets are normal and are cached which seems to be working solidly. And only enable in memory datasets explicitly if the user chooses to and then it doesn't matter if it's cached on not for the majority of the users who will not make this choice.\r\n\r\nI mean the definition of in-memory-datasets is very arbitrary - why 250MB and not 5GB? It's very likely that the user will want to set this threshold based on their RAM availability. So while doing that they can enable the in-memory-datasets. Unless I'm missing something here.\r\n\r\nThe intention here is that things work well in general out of the box, and further performance optimizations are available to those who know what they are doing.\r\n", "This is just for speed improvements, especially for data exploration/experiments in notebooks. Ideally it shouldn't have changed anything regarding caching behavior in the first place (i.e. have the caching enabled by default).\r\n\r\nThe 250MB limit has also been chosen to not create unexpected high memory usage on small laptops.", "Won't it be more straight-forward to create a performance optimization doc and share all these optimizations there? That way the user will be in the knowing and will be able to get faster speeds if their RAM is large. \r\n\r\nIt is hard for me to tell the average size of a dataset an average user will have, but my gut feeling is that many NLP datasets are larger than 250MB. Please correct me if I'm wrong.\r\n\r\nBut at the same time what you're saying is that once https://github.com/huggingface/datasets/pull/2329 is completed and merged, the in-memory-datasets will be cached too.

Thinking about the UX though, maybe we could do it without the extra argument?

Then, later in the code, we convert output dicts with only one key to naked Tensors.\r\n\r\nWould it be easier if we removed the argument, but instead treated the cases differently? Passing a column name as a string could yield a single naked Tensor in the output as before, but passing a list of length 1 would yield a full dict?

In this case, am I right in saying we'd effectively set `return_dict` [here](https://github.com/huggingface/datasets/blob/6569014a9948eab7d031a3587405e64ba92d6c59/src/datasets/arrow_dataset.py#L410) - where columns are made into a list if they were a string? \r\n\r\nThere only concern I have is this changes the default behaviour, which might break things for people who were happily using `columns=[\"my_col_str\"]` before. \r\n\r\n\r\n", "@amyeroberts That's correct! Probably the simplest way to implement it would be to just add the flag there.\r\n\r\nAnd yeah, I'm aware this might be a slightly breaking change, but we've mostly tried to move users to `prepare_tf_dataset` in `transformers` at this point, so hopefully as long as that method doesn't break then most users won't be negatively affected by the change.", "@lhoestq @Rocketknight1 - I've remove the `return_dict` argument and implemented @Rocketknight1 's suggestion.

The aim was to make `to_tf_dataset` more user friendly, but I agree that it has the potential to be confusing. \r\n\r\nFor context, the thought process behind this design was to: \r\n* Not add even more arguments to `to_tf_dataset`. \r\n* Have a feature selection -> return type logic in keeping with `datasets` e.g. `dataset['train'][:10]['feat1']` returns a list of values, whereas `dataset['train'][:10]['feat1', 'feat2']` returns a dictionary. \r\n\r\nVery happy to add any suggestions or changes you might have about how to make this design better! :) \r\n", "Hi !

[ "Hi ! In your code you only iterate on the Arrow buffers - you don't actually load the data as python objects. For a fair comparison, you can modify your code using:\r\n```diff\r\n- for _ in range(0, len(table), bsz):\r\n- _ = {k:table[k][_ : _ + bsz] for k in cols}\r\n+ for _ in range(0, len(table), bsz):\r\n+ _ = {k:table[k][_ : _ + bsz].to_pylist() for k in cols}\r\n```\r\n\r\nI re-ran your code and got a speed ratio of 1.00x and 1.02x", "Ah I see, datasets is implicitly making this conversion. Thanks for pointing that out!\r\n\r\nIf it's not too much, I would also suggest updating some of your docs with the same `.to_pylist()` conversion in the code snippet that follows [here](https://huggingface.co/course/chapter5/4?fw=pt#:~:text=let%E2%80%99s%20run%20a%20little%20speed%20test%20by%20iterating%20over%20all%20the%20elements%20in%20the%20PubMed%20Abstracts%20dataset%3A).", "This code snippet shows `datasets` code that reads the Arrow data as python objects already, there is no need to add to_pylist. Or were you thinking about something else ?" ]

[ "Good catch thanks ! Have you tried to use the absolue path in `MemoryMappedTable.__init__` in `table.py`?\r\n\r\nI think it can fix issues with relative paths at more levels than just fixing it `load_from_disk`. If it works I think it would be a more robust fix to this issue", "@lhoestq right, that actually fixed it indeed. I've pushed the changes (one-liner). lemme know if there's anything else you need for this fix", "_The documentation is not available anymore as the PR was closed or merged._" ]

(A better name for it in the current state would be `sqlite` :))\r\n* It should support arbitrary queries/table names - only the latter currently works.\r\n* Exposing this loader as a packaged builder (`load_dataset(\"sql\", ...)`) is not a good idea for the following reasons:\r\n * Considering the scenario where a table with the same name is present in multiple files is very unlikely, the data files resolution is not needed here. And if we remove that, what the name of the default split should be? \"train\"?\r\n * `load_dataset(\"sql\", ...)` also implies that streaming should work, but that's not the case. And I don't think we can change that, considering how hard it is to make SQLite files streamable.\r\n\r\nAll this makes me think we shouldn't expose this builder as a packaged module and, instead, limit the API to `Dataset.from_sql`/`Dataset.to_sql` (with the signatures matching the ones in pandas as much as possible; regarding this, note that SQLAlchemy connections are not hashable/picklable, which is required for caching, but I think it's OK only to allow URI strings as connections to bypass that (Dask has the same limitation).\r\n\r\nWDYT?", "Hi @mariosasko thank you for your review.\r\n\r\nI agree that `load_dataset('sql',...)` is a bit weird and I would be happy to remove it. To be honest, I only added it when I saw that it was the preferred way in `loading.mdx`. \r\n\r\nI agree that the `SELECT` should be a parameters as well. I'll add it.\r\n\r\nSo far, only `Dataset.to_sql` explicitly supports any SQLAlchemy Connexion, I'm pretty sure that `Dataset.from_sql` would work with a Connexion as well, but it would break the typing from the parent class which is `path_or_paths: NestedDataStructureLike[PathLike]`. I would prefer not to break this API Contract.\r\n\r\n\r\nI will have time to work on this over the weekend. Please let me know what you think if I do the following:\r\n* Remove `load_dataset('sql', ...)` and edit the documentation to use `to_sql, from_sql`.\r\n* Tentatively make `Dataset.from_sql` typing work with SQLAlchemy Connexion.\r\n* Add support for custom queries (Default would be `SELECT * FROM {table_name}`).\r\n\r\nCheers!", "Perhaps after we merge https://github.com/huggingface/datasets/pull/4957 (**Done!**), you can subclass `AbstractDatasetInputStream` instead of `AbstractDatasetReader` to not break the contract with the connection object. Also, let's avoid having the default value for the query/table (you can set it to `None` in the builder and raise an error in the builder config's `__post_init__` if it's not provided).

Do you think we should be the ones throwing this error, e.g. after the imports in `packaged_modules/sql/sql.py` if `SQLALCHEMY_AVAILABLE` is `False` (note that this would mean making `sqlalchemy` a required dependency for the docs to be able to add `SqlConfig` to the package reference)?", "> One last thing I would like to get your opinion on - currently, if SQLAlchemy is not installed, the missing dependency error will be thrown inside pandas.read_sql\r\n\r\nIs sqlalchemy always required for pd.read_sql ?
