But the default code did not work because ``` FileNotFoundError: Couldn't find a dataset script at jsonl\jsonl.py or any data file in the same directory. Couldn't find 'jsonl' on the Hugging Face Hub either: FileNotFoundError: Dataset 'jsonl' doesn't exist on the Hub. If the repo is private or gated, make sure to log in with `huggingface-cli login`. ``` The reason is because the script has these lines to extract the data type by its extension. Therefore, the derived type is `jsonl` which is not recognized by datasets as the error above shows. https://github.com/huggingface/transformers/blob/ade26bf9912f69e2110137443e4406d7dbe253e7/examples/pytorch/translation/run_translation.py#L342-L356 I suppose you could argue that this is the script's fault (in which case I'll do a PR over at `transformers`) but it makes sense to me to add `jsonl` as an alias to `json` in `datasets`. ### Your contribution At the moment I cannot work on this. I think it can be as "easy" as having an alias for json, namely jsonl.	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5625/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5625/timeline	null	null	false

"merged_at": "2023-03-09T15:31:58" }	`set_access_token` is deprecated and will be removed in `huggingface_hub>=0.14`. This PR removes it from the tests (it was not used in `datasets` source code itself). FYI, it was not needed since `set_access_token` was just setting git credentials and `datasets` doesn't seem to use git anywhere. In the future, use `set_git_credential` if needed. It is a git-credential-agnostic helper, i.e. you can store your git token in `git-credential-cache`, `git-credential-store`, `osxkeychain`, etc. The legacy `set_access_token` could only set in `git-credential-store` no matter the user preference. (for context, I found out about this while working on https://github.com/huggingface/huggingface_hub/pull/1381) --- In addition to this, I have added ``` filterwarnings = error::FutureWarning:huggingface_hub* ``` to the `setup.cfg` config file to fail on future warnings from `huggingface_hub`. In `hfh`'s CI we trigger on FutureWarning from any package but it's less robust (any package update leads can lead to a failure). No obligation to keep it like that (I can remove it if you prefer) but I think it's a good idea in order to track future FutureWarnings. FYI, in `huggingface_hub` tests we use `-Werror::FutureWarning --log-cli-level=INFO -sv --durations=0` - FutureWarning are processed as error - verbose mode / INFO logs (and above) are captured for easier debugging in github report - track each test duration, just to see where we can improve. We have a quite long CI (~10min) so it helped improve that.	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5623/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5623/timeline	null	null	true

The method seems to accept only eager evaluated values. https://github.com/huggingface/datasets/blob/35b789e8f6826b6b5a6b48fcc2416c890a1f326a/src/datasets/iterable_dataset.py#L1388-L1391 I wrote codes below to make it. ```py def add_column(dataset: IterableDataset, name: str, add_dataset: IterableDataset, key: str) -> IterableDataset: iter_add_dataset = iter(add_dataset) def add_column_fn(example): if name in example: raise ValueError(f"Error when adding {name}: column {name} is already in the dataset.") return {name: next(iter_add_dataset)[key]} return dataset.map(add_column_fn) ``` Is there other way to do it? Or is it intended? ### Steps to reproduce the bug Thie codes below occurs `NotImplementedError` ```py from datasets import IterableDataset def gen(num): yield {f"col{num}": 1} yield {f"col{num}": 2} yield {f"col{num}": 3} ids1 = IterableDataset.from_generator(gen, gen_kwargs={"num": 1}) ids2 = IterableDataset.from_generator(gen, gen_kwargs={"num": 2}) new_ids = ids1.add_column("new_col", ids1) for row in new_ids: print(row) ``` ### Expected behavior `IterableDataset.add_column` is able to task `IterableDataset` and lazy evaluated values as a parameter since IterableDataset is lazy evalued. ### Environment info - `datasets` version: 2.8.0 - Platform: Linux-3.10.0-1160.36.2.el7.x86_64-x86_64-with-glibc2.17 - Python version: 3.9.7 - PyArrow version: 11.0.0 - Pandas version: 1.5.3	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5615/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5615/timeline	null	completed	false

The crash is ``` File "/Users/adpauls/sc/git/DSI-transformers/data/NQ/create_NQ_train_vali.py", line 1, in <module> import datasets File "/Users/adpauls/Library/Caches/pypoetry/virtualenvs/yyy-oPbZ7mKM-py3.10/lib/python3.10/site-packages/datasets/__init__.py", line 43, in <module> from .arrow_dataset import Dataset File "/Users/adpauls/Library/Caches/pypoetry/virtualenvs/yyy-oPbZ7mKM-py3.10/lib/python3.10/site-packages/datasets/arrow_dataset.py", line 65, in <module> from .arrow_reader import ArrowReader File "/Users/adpauls/Library/Caches/pypoetry/virtualenvs/yyy-oPbZ7mKM-py3.10/lib/python3.10/site-packages/datasets/arrow_reader.py", line 30, in <module> from .download.download_config import DownloadConfig File "/Users/adpauls/Library/Caches/pypoetry/virtualenvs/yyy-oPbZ7mKM-py3.10/lib/python3.10/site-packages/datasets/download/__init__.py", line 9, in <module> from .download_manager import DownloadManager, DownloadMode File "/Users/adpauls/Library/Caches/pypoetry/virtualenvs/yyy-oPbZ7mKM-py3.10/lib/python3.10/site-packages/datasets/download/download_manager.py", line 35, in <module> from ..utils.py_utils import NestedDataStructure, map_nested, size_str File "/Users/adpauls/Library/Caches/pypoetry/virtualenvs/yyy-oPbZ7mKM-py3.10/lib/python3.10/site-packages/datasets/utils/py_utils.py", line 40, in <module> import multiprocess.pool File "/Users/adpauls/Library/Caches/pypoetry/virtualenvs/yyy-oPbZ7mKM-py3.10/lib/python3.10/site-packages/multiprocess/pool.py", line 609, in <module> class ThreadPool(Pool): File "/Users/adpauls/Library/Caches/pypoetry/virtualenvs/yyy-oPbZ7mKM-py3.10/lib/python3.10/site-packages/multiprocess/pool.py", line 611, in ThreadPool from .dummy import Process File "/Users/adpauls/Library/Caches/pypoetry/virtualenvs/yyy-oPbZ7mKM-py3.10/lib/python3.10/site-packages/multiprocess/dummy/__init__.py", line 87, in <module> class Condition(threading._Condition): AttributeError: module 'threading' has no attribute '_Condition'. Did you mean: 'Condition'? ``` I think this is a bad interaction of versions from `dill`, `multiprocess`, `apache-beam`, and `threading` from the Python (3.10) standard lib. Upgrading `multiprocess` to a version that does not crash like this is not possible because `apache-beam` pins `dill` to and old version: ``` Because multiprocess (0.70.10) depends on dill (>=0.3.2) and apache-beam (2.45.0) depends on dill (>=0.3.1.1,<0.3.2), multiprocess (0.70.10) is incompatible with apache-beam (2.45.0). And because no versions of apache-beam match >2.45.0,<3.0.0, multiprocess (0.70.10) is incompatible with apache-beam (>=2.45.0,<3.0.0). So, because yyy depends on both apache-beam (^2.45.0) and multiprocess (0.70.10), version solving failed. ``` Perhaps it is not right to file a bug here, but I'm not totally sure whose fault it is. And in any case, this is an immediate blocker to using `datasets` out of the box. Possibly related to https://github.com/huggingface/datasets/issues/5232. ### Steps to reproduce the bug Steps to reproduce: 1.

Now, I would like to use this filtered version for future work. It seems I have two choices: 1. Use `load_dataset` each time, relying on the cache mechanism, and re-run my filtering. 2. `save_to_disk` and then use `load_from_disk` to load the filtered version. The performance of these two approaches is wildly different: * Using `load_dataset` takes about 20 seconds to load the dataset, and a few seconds to re-filter (thanks to the brilliant filter/map caching) * Using `load_from_disk` takes 14 minutes! And the second time I tried, the session just crashed (on a machine with 32GB of RAM) I don't know if you'd call this a bug, but it seems like there shouldn't need to be two methods to load from disk, or that they should not take such wildly different amounts of time, or that one should not crash. Or maybe that the docs could offer some guidance about when to pick which method and why two methods exist, or just how do most people do it? Something I couldn't work out from reading the docs was this: can I modify a dataset from the hub, save it (locally) and use `load_dataset` to load it? This [post seemed to suggest that the answer is no](https://discuss.huggingface.co/t/save-and-load-datasets/9260). ### Steps to reproduce the bug See above ### Expected behavior Load times should be about the same. ### Environment info - `datasets` version: 2.9.0 - Platform: Linux-5.10.102.1-microsoft-standard-WSL2-x86_64-with-glibc2.31 - Python version: 3.10.8 - PyArrow version: 11.0.0 - Pandas version: 1.5.3	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5609/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5609/timeline	null	null	false

All of your documentation changes will be reflected on that endpoint.", "This is a great PR! Thinking about the UX though, maybe we could do it without the extra argument? Before this PR, the logic in `to_tf_dataset` was that if the user passed a single column name in either `columns` or `label_cols`, we converted it to a length-1 list. 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? That way if you wanted dict output with a single key you could just say `columns=[col_name]`.\r\n\r\n(I'm not totally convinced this is a good idea yet, it just seems like it might be more intuitive)", "@Rocketknight1 Happy to implement it that way - it's certainly cleaner to not have another arg. 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. LMK what you think :) ", "@lhoestq Of course :) I've opened a draft PR here for the updates needed in transformers examples and docs to keep the returned data structure consistent: https://github.com/huggingface/transformers/pull/21935.

This PR isn't really a model specific change - although it was highlighted when trying to train a model.

Personally, I found it surprising to be returned a tuple structure when I was using `to_tf_dataset`. 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 !

I could open a PR to add a warning message within `to_tf_dataset`?", "Yup sounds good :)" ]	2023-03-02T15:51:12	2023-04-12T15:54:53	null	CONTRIBUTOR	null	false	{ "url": "https://api.github.com/repos/huggingface/datasets/pulls/5602", "html_url": "https://github.com/huggingface/datasets/pull/5602", "diff_url": "https://github.com/huggingface/datasets/pull/5602.diff", "patch_url": "https://github.com/huggingface/datasets/pull/5602.patch", "merged_at": null }	This PR introduces new logic to `to_tf_dataset` affecting the returned data structure, enabling a dictionary structure to be returned, even if only one feature column is selected. If the passed in `columns` or `label_cols` to `to_tf_dataset` are a list, they are returned as a dictionary, respectively. If they are a string, the tensor is returned. An outline of the behaviour: ``` dataset,to_tf_dataset(columns=["col_1"], label_cols="col_2") # ({'col_1': col_1}, col_2} dataset,to_tf_dataset(columns="col1", label_cols="col_2") # (col1, col2) dataset,to_tf_dataset(columns="col1") # col1 dataset,to_tf_dataset(columns=["col_1"], labels=["col_2"]) # ({'col1': tensor}, {'col2': tensor}} dataset,to_tf_dataset(columns="col_1", labels=["col_2"]) # (col1, {'col2': tensor}} ``` ## Motivation Currently, when calling `to_tf_dataset`, the returned dataset will always return a tuple structure if a single feature column is used. This can cause issues when calling `model.fit` on models which train without labels e.g. [TFVitMAEForPreTraining](https://github.com/huggingface/transformers/blob/b6f47b539377ac1fd845c7adb4ccaa5eb514e126/src/transformers/models/vit_mae/modeling_vit_mae.py#L849). Specifically, [this line](https://github.com/huggingface/transformers/blob/d9e28d91a8b2d09b51a33155d3a03ad9fcfcbd1f/src/transformers/modeling_tf_utils.py#L1521) where it's assumed the input `x` is a dictionary if there is no label. ## Example Previous behaviour ```python In [1]: import tensorflow as tf ...: from datasets import load_dataset ...: ...: ...: def transform(batch): ...: def _transform_img(img): ...: img = img.convert("RGB") ...: img = tf.keras.utils.img_to_array(img) ...: img = tf.image.resize(img, (224, 224)) ...: img /= 255.0 ...: img = tf.transpose(img, perm=[2, 0, 1]) ...: return img ...: batch['pixel_values'] = [_transform_img(pil_img) for pil_img in batch['img']] ...: return batch ...: ...: ...: def collate_fn(examples): ...: pixel_values = tf.stack([example["pixel_values"] for example in examples]) ...: return {"pixel_values": pixel_values} ...: ...: ...: dataset = load_dataset('cifar10')['train'] ...: dataset = dataset.with_transform(transform) ...: dataset.to_tf_dataset(batch_size=8, columns=['pixel_values'], collate_fn=collate_fn) Out[1]: <PrefetchDataset element_spec=TensorSpec(shape=(None, 3, 224, 224), dtype=tf.float32, name=None)> ``` New behaviour ```python In [1]: import tensorflow as tf ...: from datasets import load_dataset ...: ...: ...: def transform(batch): ...: def _transform_img(img): ...: img = img.convert("RGB") ...: img = tf.keras.utils.img_to_array(img) ...: img = tf.image.resize(img, (224, 224)) ...: img /= 255.0 ...: img = tf.transpose(img, perm=[2, 0, 1]) ...: return img ...: batch['pixel_values'] = [_transform_img(pil_img) for pil_img in batch['img']] ...: return batch ...: ...: ...: def collate_fn(examples): ...: pixel_values = tf.stack([example["pixel_values"] for example in examples]) ...: return {"pixel_values": pixel_values} ...: ...: ...: dataset = load_dataset('cifar10')['train'] ...: dataset = dataset.with_transform(transform) ...: dataset.to_tf_dataset(batch_size=8, columns=['pixel_values'], collate_fn=collate_fn) Out[1]: <PrefetchDataset element_spec={'pixel_values': TensorSpec(shape=(None, 3, 224, 224), dtype=tf.float32, name=None)}> ```	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5602/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5602/timeline	null	null	true

It looks quite memory-consuming. I just wonder if there is any more efficient way to do this. ```python from datasets import Dataset ds = Dataset.from_list([]) ds.add_item({'a': [1, 2, 3], 'b': 4}) print(ds) >>> Dataset({ >>> features: [], >>> num_rows: 0 >>> }) ds = ds.add_item({'a': [1, 2, 3], 'b': 4}) print(ds) >>> Dataset({ >>> features: ['a', 'b'], >>> num_rows: 1 >>> }) ``` ### Feature request Call for in-place dataset update functions, that update the existing `Dataset` in place without creating a new copy. The interface is supposed to keep the same style as PyTorch, such as the in-place version of a `function` is named `function_`. For example, the in-pace version of `add_item`, i.e., `add_item_`, immediately updates the `Dataset`. ```python from datasets import Dataset ds = Dataset.from_list([]) ds.add_item({'a': [1, 2, 3], 'b': 4}) print(ds) >>> Dataset({ >>> features: [], >>> num_rows: 0 >>> }) ds.add_item_({'a': [1, 2, 3], 'b': 4}) print(ds) >>> Dataset({ >>> features: ['a', 'b'], >>> num_rows: 1 >>> }) ``` ### Related Functions * `.map` * `.filter` * `.add_item`	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5597/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5597/timeline	null	completed	false

I am able to download other datasets using the same code on the same machine with no issues :( I get this error now : \r\n```\r\nDownloading data: 16%\|███████████████▌ \| 55.9M/355M [04:45<25:25, 196kB/s]\r\nTraceback (most recent call last):\r\n File \"/home/skhanuja/Optimal-Resource-Allocation-for-Multilingual-Finetuning/src/train_al.py\", line 1107, in <module>\r\n main()\r\n File \"/home/skhanuja/Optimal-Resource-Allocation-for-Multilingual-Finetuning/src/train_al.py\", line 439, in main\r\n en_dataset = load_dataset(\"xtreme\", \"udpos.English\", split=\"train\", download_mode=\"force_redownload\", verification_mode=\"all_checks\")\r\n File \"/home/skhanuja/miniconda3/envs/multilingual_ft/lib/python3.10/site-packages/datasets/load.py\", line 1782, in load_dataset\r\n builder_instance.download_and_prepare(\r\n File \"/home/skhanuja/miniconda3/envs/multilingual_ft/lib/python3.10/site-packages/datasets/builder.py\", line 872, in download_and_prepare\r\n self._download_and_prepare(\r\n File \"/home/skhanuja/miniconda3/envs/multilingual_ft/lib/python3.10/site-packages/datasets/builder.py\", line 1649, in _download_and_prepare\r\n super()._download_and_prepare(\r\n File \"/home/skhanuja/miniconda3/envs/multilingual_ft/lib/python3.10/site-packages/datasets/builder.py\", line 949, in _download_and_prepare\r\n verify_checksums(\r\n File \"/home/skhanuja/miniconda3/envs/multilingual_ft/lib/python3.10/site-packages/datasets/utils/info_utils.py\", line 62, in verify_checksums\r\n raise NonMatchingChecksumError(\r\ndatasets.utils.info_utils.NonMatchingChecksumError: Checksums didn't match for dataset source files:\r\n['https://lindat.mff.cuni.cz/repository/xmlui/bitstream/handle/11234/1-3105/ud-treebanks-v2.5.tgz']\r\nSet `verification_mode='no_checks'` to skip checksums verification and ignore this error\r\n```", "If this happens randomly, then this means the data file from the error message is not always downloaded correctly. \r\n\r\nThe only solution in this scenario is to download the dataset again by passing `download_mode=\"force_redownload\"` to the `load_dataset` call." ]	2023-02-28T23:40:53	2023-07-24T14:22:18	2023-07-24T14:22:18	NONE	null	null	null	### Describe the bug Hi, I am facing an error while downloading the xtreme udpos dataset using load_dataset.

It seems like the addition of multiple key sort (#5502) in 2.10.0 broke the `.sort()` method. After filtering a dataset with `.filter()`, the `.sort()` seems to refer to the query_table index of the previous unfiltered dataset, resulting in an IndexError. This only happens with the 2.10.0 release. ### Steps to reproduce the bug ```Python from datasets import load_dataset # dataset with length of 1104 ds = load_dataset('glue', 'ax')['test'] ds = ds.filter(lambda x: x['idx'] > 1100) ds.sort('premise') print('Done') ``` File "/home/dongkeun/datasets_test/test.py", line 5, in <module> ds.sort('premise') File "/home/dongkeun/miniconda3/envs/datasets_test/lib/python3.9/site-packages/datasets/arrow_dataset.py", line 528, in wrapper out: Union["Dataset", "DatasetDict"] = func(self, args, kwargs) File "/home/dongkeun/miniconda3/envs/datasets_test/lib/python3.9/site-packages/datasets/fingerprint.py", line 511, in wrapper out = func(dataset, args, **kwargs) File "/home/dongkeun/miniconda3/envs/datasets_test/lib/python3.9/site-packages/datasets/arrow_dataset.py", line 3959, in sort sort_table = query_table( File "/home/dongkeun/miniconda3/envs/datasets_test/lib/python3.9/site-packages/datasets/formatting/formatting.py", line 588, in query_table _check_valid_index_key(key, size) File "/home/dongkeun/miniconda3/envs/datasets_test/lib/python3.9/site-packages/datasets/formatting/formatting.py", line 537, in _check_valid_index_key _check_valid_index_key(max(key), size=size) File "/home/dongkeun/miniconda3/envs/datasets_test/lib/python3.9/site-packages/datasets/formatting/formatting.py", line 531, in _check_valid_index_key raise IndexError(f"Invalid key: {key} is out of bounds for size {size}") IndexError: Invalid key: 1103 is out of bounds for size 3 ### Expected behavior It should sort the dataset and print "Done".

I run most my code in WSL. I have just run out of space in the virtual drive. Rather than expand the drive size, I plan to move to cache to the host Windows machine, thereby sharing the downloads. I'm hoping that I can just copy/paste the cache files, but I notice that a lot of the file names start with the path name, e.g. `_home_davidg_.cache_huggingface_datasets_conll2003_default-451...98.lock` where `home/davidg` is where the cache is in WSL. This seems to suggest that the cache is not portable/cannot be centralised or shared. Is this the case, or are the files that start with path names not integral to the caching mechanism? Because copying the cache files _seems_ to work, but I'm not filled with confidence that something isn't going to break. A related issue, when trying to load a dataset that should come from cache (running in WSL, pointing to cache on the Windows host) it seemed to work fine, but it still uses a WSL directory for `.cache\huggingface\modules\datasets_modules`. I see nothing in the docs about this, or how to point it to a different place. I have asked a related question on the forum: https://discuss.huggingface.co/t/is-datasets-cache-operating-system-agnostic/32656 ### Steps to reproduce the bug View the cache directory in WSL/Windows. ### Expected behavior Cache can be shared between (virtual) machines and be transportable. It would be nice to have a simple way to say "Dear Hugging Face packages, please put ALL your cache in `blah/de/blah`" and have all the Hugging Face packages respect that single location. ### Environment info ``` - `datasets` version: 2.9.0 - Platform: Linux-5.10.102.1-microsoft-standard-WSL2-x86_64-with-glibc2.31 - Python version: 3.10.8 - PyArrow version: 11.0.0 - Pandas version: 1.5.3 - ```	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5585/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5585/timeline	null	completed	false

ETags are currently unsupported for cloud storage. In general, a much larger refactor could be done to just use fsspec for all schemes (ftp, http/s, s3, gcs) to unify the interfaces here, but I ultimately opted to leave that out of this PR I didn't create a GCS filesystem class in `datasets.filesystems` since the S3 one appears to be a wrapper around `s3fs.S3FileSystem` and mainly used to generate docs.	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5580/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5580/timeline	null	null	true

"merged_at": "2023-02-28T20:16:02" }	I've removed `torchaudio` completely and switched to use `soundfile` for everything. With the new version of `soundfile` package this should work smoothly because the `libsndfile` C library is bundled, in Linux wheels too. Let me know if you think it's too harsh and we should continue to support `torchaudio` decoding. I decided that we can drop it completely because: 1. it's always something wrong with `torchaudio` (for example recently https://github.com/huggingface/datasets/issues/5488 ) 2. the results of mp3 decoding are different depending on `torchaudio` version 3. `soundfile` is slightly faster then the latest `torchaudio` 4. anyway users can pass any custom decoding function with any library they want if needed (worth putting a snippet in the docs). cc @sanchit-gandhi @vaibhavad	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5573/reactions", "total_count": 3, "+1": 0, "-1": 0, "laugh": 0, "hooray": 3, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5573/timeline	null	null	true

When using `to_iterable_dataset` to transform your map style dataset into iterable dataset, you lose valuable metadata like the features. These metadata are useful if you want to interleave iterable datasets, cast columns etc. ### Steps to reproduce the bug ```python dataset = load_dataset("lhoestq/demo1")["train"] print(dataset.features) # {'id': Value(dtype='string', id=None), 'package_name': Value(dtype='string', id=None), 'review': Value(dtype='string', id=None), 'date': Value(dtype='string', id=None), 'star': Value(dtype='int64', id=None), 'version_id': Value(dtype='int64', id=None)} dataset = dataset.to_iterable_dataset() print(dataset.features) # None ``` ### Expected behavior Keep the relevant information ### Environment info datasets==2.10.0	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5568/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5568/timeline	null	completed	false

If you reuse this transform, the caching mechanism will consider it to be different from the previous calls and recompute everything. This warning is only showed once. Subsequent hashing failures won't be showed.\r\n```\r\n\r\nThat's why I decided to map all the available devices, and assign their string representation e.g. `TFRT_CPU_0` to `self.device` instead of `jaxlib.xla_extension.Device`, so that the value of the param `device` is washable. So on, the code that remains at the end is:\r\n\r\n```python\r\nclass JaxFormatter(Formatter[Mapping, \"jax.Array\", Mapping]):\r\n def __init__(self, features=None, device=None, jnp_array_kwargs):\r\n super().__init__(features=features)\r\n import jax\r\n from jaxlib.xla_client import Device\r\n\r\n self.device_mapping = self._map_devices_to_str()\r\n self.device = (\r\n device if isinstance(device, str) else str(device) if isinstance(device, Device) else str(jax.devices()[0])\r\n )\r\n self.jnp_array_kwargs = jnp_array_kwargs\r\n\r\n def _map_devices_to_str(self) -> Mapping[str, \"jaxlib.xla_extension.Device\"]:\r\n import jax\r\n\r\n return {str(device): device for device in jax.devices()}\r\n\r\n ...\r\n\r\n def _tensorize(self, value):\r\n ...\r\n\r\n with jax.default_device(self.device_mapping[self.device]):\r\n # calling jnp.array on a np.ndarray does copy the data\r\n # see https://github.com/google/jax/issues/4486\r\n return jnp.array(value, {default_dtype, self.jnp_array_kwargs})\r\n```\r\n\r\nBut note that the latter also throws a warning if the provided `device` is not a string but a `jaxlib.xla_extension.Device`, so that's why it needs to be converted to string.", "_The documentation is not available anymore as the PR was closed or merged._", "After some investigation, it seems that when using `device=jaxlib.xla_extension.Device` instead of `device=string` it shows the warning so that later formats fail as that cannot be unpickled.\r\n\r\nSo I think we can either add that specifically in `use_with_jax.mdx` documentation entry I'm creating at #5535 so that the users know that they need to surroung the `jaxlib.xla_extension.Device` with `str()`, or find a workaround to override default `deepcopy` behavior with `def __deepcopy__(self)` so that the device param is converted to string if provided as a `jaxlib.xla_extension.Device`, but not sure if the latter works 😕 \r\n\r\nDo you think there's any other possible solution to this issue?

"merged_at": "2023-02-21T16:04:03" }	## What's in this PR? After exploring for a while the JAX integration in 🤗`datasets`, I found out that, even though JAX prioritizes the TPU and GPU as the default device when available, the `JaxFormatter` doesn't let you specify the device where you want to place the `jax.Array`s in case you don't want to rely on JAX's default array placement. So on, I've included the `device` param in `JaxFormatter` but there are some things to take into consideration: * A formatted `Dataset` is copied with `copy.deepcopy` which means that if one adds the param `device` in `JaxFormatter` as a `jaxlib.xla_extension.Device`, it "fails" because that object cannot be serialized (instead of serializing the param adds a random hash instead). That's the reason why I added a function `_map_devices_to_str` to basically create a mapping of strings to `jaxlib.xla_extension.Device`s so that `self.device` is a string and not a `jaxlib.xla_extension.Device`. * To create a `jax.Array` in a device you need to either create it in the default device and then move it to the desired device with `jax.device_put` or directly create it in the device you want with `jax.default_device()` context manager. * JAX will create an array by default in `jax.devices()[0]` More information on JAX device management is available at https://jax.readthedocs.io/en/latest/faq.html#controlling-data-and-computation-placement-on-devices ## What's missing in this PR? I've tested it both locally in CPU (Mac M2 and Mac M1, as no GPU support for Mac yet), and in GPU and TPU in Google Colab, let me know if you want me to provide you the Notebook for the latter. But I did not implement any integration test as I wanted to get your feedback first.	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5547/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5547/timeline	null	null	true

Currently, flattening such dataset consumes a lot of memory and the resulting flat dataset contains ChunkedArrays with as many chunks as there are rows. This is extremely inefficient and slows down the operations on the flat dataset, e.g., saving/loading the dataset to disk becomes really slow. Perhaps more importantly, loading the dataset back from disk basically loads the whole table into RAM, as it cannot take advantage of memory mapping. ### Steps to reproduce the bug The following script reproduces the issue: ```python import gc import os import psutil import tempfile import time from datasets import Dataset DATASET_SIZE = 5000000 def profile(func): def wrapper(args, kwargs): mem_before = psutil.Process(os.getpid()).memory_info().rss / (1024 1024) start = time.time() # Run function here out = func(args, kwargs) end = time.time() mem_after = psutil.Process(os.getpid()).memory_info().rss / (1024 1024) print(f"{func.__name__} -- RAM memory used: {mem_after - mem_before} MB -- Total time: {end - start:.6f} s") return out return wrapper def main(): ds = Dataset.from_list([{'col': i} for i in range(DATASET_SIZE)]) print(f"Num chunks for original ds: {ds.data['col'].num_chunks}") with tempfile.TemporaryDirectory() as tmpdir: path1 = os.path.join(tmpdir, 'ds1') print("Original ds save/load") profile(ds.save_to_disk)(path1) ds_loaded = profile(Dataset.load_from_disk)(path1) print(f"Num chunks for original ds after reloading: {ds_loaded.data['col'].num_chunks}") print("") ds_select = ds.select(reversed(range(len(ds)))) print(f"Num chunks for selected ds: {ds_select.data['col'].num_chunks}") del ds del ds_loaded gc.collect() # This would happen anyway when we call save_to_disk ds_select = profile(ds_select.flatten_indices)() print(f"Num chunks for selected ds after flattening: {ds_select.data['col'].num_chunks}") print("") path2 = os.path.join(tmpdir, 'ds2') print("Selected ds save/load") profile(ds_select.save_to_disk)(path2) del ds_select gc.collect() ds_select_loaded = profile(Dataset.load_from_disk)(path2) print(f"Num chunks for selected ds after reloading: {ds_select_loaded.data['col'].num_chunks}") if __name__ == '__main__': main() ``` Sample result: ``` Num chunks for original ds: 1 Original ds save/load save_to_disk -- RAM memory used: 0.515625 MB -- Total time: 0.253888 s load_from_disk -- RAM memory used: 42.765625 MB -- Total time: 0.015176 s Num chunks for original ds after reloading: 5000 Num chunks for selected ds: 1 flatten_indices -- RAM memory used: 4852.609375 MB -- Total time: 46.116774 s Num chunks for selected ds after flattening: 5000000 Selected ds save/load save_to_disk -- RAM memory used: 1326.65625 MB -- Total time: 42.309825 s load_from_disk -- RAM memory used: 2085.953125 MB -- Total time: 11.659137 s Num chunks for selected ds after reloading: 5000000 ``` ### Expected behavior Saving/loading the dataset should be much faster and consume almost no extra memory thanks to pyarrow memory mapping. ### Environment info - `datasets` version: 2.9.1.dev0 - Platform: macOS-13.1-arm64-arm-64bit - Python version: 3.10.8 - PyArrow version: 11.0.0 - Pandas version: 1.5.3	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5541/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5541/timeline	null	completed	false

This comes from `resolve_patterns_in_dataset_repository` which calls `_resolve_single_pattern_in_dataset_repository`, which iterates on all the files at ```python glob_iter = [PurePath(filepath) for filepath in fs.glob(PurePath(pattern).as_posix()) if fs.isfile(filepath)] ``` but calling `glob` on such a dataset is too expensive.

Make sure your transforms and parameters are serializable with pickle or dill for the dataset fingerprinting and caching to work. If you reuse this transform, the caching mechanism will consider it to be different from the previous calls and recompute everything. This warning is only showed once. Subsequent hashing failures won't be showed._ This issue with `.map()` happens for me consistently, as also described in closed issue #4506 Dataset indices can be individually serialized using dill and pickle without any errors. I'm using tiktoken to encode in the function passed to map(). Similarly, indices can be individually encoded without error. ### Steps to reproduce the bug ```py from datasets import load_dataset import tiktoken dataset = load_dataset("stas/openwebtext-10k") enc = tiktoken.get_encoding("gpt2") tokenized = dataset.map( process, remove_columns=['text'], desc="tokenizing the OWT splits", ) def process(example): ids = enc.encode(example['text']) ids.append(enc.eot_token) out = {'ids': ids, 'len': len(ids)} return out ``` ### Expected behavior Should encode simple text objects. ### Environment info Python versions tried: both 3.8 and 3.10.10 `PYTHONUTF8=1` as env variable Datasets tried: - stas/openwebtext-10k - rotten_tomatoes - local text file OS: Ubuntu Linux 20.04 Package versions: - torch 1.13.1 - dill 0.3.4 (if using 0.3.6 - same issue) - datasets 2.9.0 - tiktoken 0.2.0	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5536/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5536/timeline	null	completed	false

After playing around a little bit with 🤗`datasets` in Google Cloud Storage (GCS), I found out some things that should be fixed IMO in the code: * `datasets.load_from_disk` is not checking whether `state.json` is there too when trying to load a `Dataset`, just `dataset_info.json` is checked * `DatasetDict.load_from_disk` is not checking whether `state.json` is there too when redirecting the user to load it as `datasets.load_from_disk`, just `dataset_info.json` is checked, which is misleading, as it won't be loadable that way either * `Dataset.load_from_disk` is missing the `extract_path_from_uri` call before checking in the `fs` whether `dataset_info.json` and `dataset_dict.json` exist, which when using `gcsfs` leads to 400 error code (not blocking) due to `gcsfs.retry.HttpError: Invalid bucket name: 'gs:', 400` * And, finally, the exception messages are a little bit misleading / incomplete IMO so I've tried to include all the relevant information in the messages to avoid issues when interpreting the exceptions	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5529/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5529/timeline	null	null	true

Do you have any advice?", "I tried to move all of the \"create pr safely\"-logic to a seperate function in `_hf_hub_fixes`. I looked at how the exceptions were raised before `huggingface_hub.utils.RepositoryNotFoundError`existed, and make changes accordingly. ", "`create_pr` was set during `push_to_hub`, even though it was `None` from the outset, hence causing tests to fail for older versions of `huggingface_hub`. This is now fixed.\r\n\r\nWith the implementation of `_hf_hub_fixes.upload_file` the function call expected `commit_message`, `commit_description`. If these are not set we call the function without them, even though we are on a version of `huggingface_hub` where they are not available in `upload_file`.\r\n\r\nWhen `huggingface_hub < 0.5.0` we assume `repo_id` of them form `organisation/name`, so now that we are calling `create_repo` in the tests with `repo_id` not of this form, we need to handle this case, this is now done.\r\n\r\nMany tests failed for `dataset_dict` for the above reasons, so the fixes from `arrow_dataset.py` were also added to `dataset_dict.py`. \r\n\r\nAll tests are now passing locally for `huggingface_hub==0.2.0` and `huggingface_hub==0.12.1`…** Im sorry I should have downgraded and went through this a long time ago, but I didn’t realise the extend of these version fixes until recently…", "Hi !

I alredy tried reseting the shorter strings (reset_cortas function). It only happends with NL, PL, RO and PT. It does not make sense since when processing the other languages I also use the corpus of those that fail and it does not cause any errors. I suspect that the error may be in this direction: We use cast_array_to_feature to support casting to custom types like Audio and Image # Also, when trying type "string", we don't want to convert integers or floats to "string". # We only do it if trying_type is False - since this is what the user asks for. ### Steps to reproduce the bug Here I link a colab notebook to reproduce the error: https://colab.research.google.com/drive/1JCrS7FlGfu_kFqChMrwKZ_bpabnIMqbP?authuser=1#scrollTo=FBAvlhMxIzpA ### Expected behavior Data processing does not fail.

Before creating this PR the average time of the `check_code_quality` job was around 40s.~~ ## Edit Sorry for the inconvenience this may have caused, didn't realise that the config is defined in `setup.cfg` and `pyproject.toml`, so running those without installing the Python package leads to failure, my bad 😞	{ "url": "https://api.github.com/repos/huggingface/datasets/issues/5524/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }	https://api.github.com/repos/huggingface/datasets/issues/5524/timeline	null	null	true
