TODO: - [x] Add a section in the docs about this. - ~Add a warning if someone tries to specify `cache_file_name=` in `map`, `filter` etc. on a dataset that is in memory, since the computation is not going to be cached in this case.~

Thank you for your prompt reply.\r\nI have experimented with (10<<20, 10<<28, 10<<30, 10<<33, 10<<34), since my machine has 192G of memory, but it's either the above-mentioned error or processed killed because of OOM.\r\n\r\nCould you give me a bit of background on why block size needs to be exactly calibrated?\r\nTo my understanding, small block sized should run just fine despite its slowness..\r\n\r\n\r\n", "We're using the JSON loader of pyarrow. It parses the file chunk by chunk to load the dataset.\r\nThis issue happens when there's no delimiter in one chunk of data.

Hi, thanks for the great library. I have used the brilliant library for a couple of small projects, and now using it for a fairly big project. When loading a huge json file of 500GB, pyarrow complains as follows: ``` Traceback (most recent call last): File "/home/user/.pyenv/versions/3.7.9/lib/python3.7/site-packages/datasets/builder.py", line 531, in incomplete_dir yield tmp_dir File "/home/user/.pyenv/versions/3.7.9/lib/python3.7/site-packages/datasets/builder.py", line 573, in download_and_prepare dl_manager=dl_manager, verify_infos=verify_infos, **download_and_prepare_kwargs File "/home/user/.pyenv/versions/3.7.9/lib/python3.7/site-packages/datasets/builder.py", line 650, in _download_and_prepare self._prepare_split(split_generator, **prepare_split_kwargs) File "/home/user/.pyenv/versions/3.7.9/lib/python3.7/site-packages/datasets/builder.py", line 1027, in _prepare_split for key, table in utils.tqdm(generator, unit=" tables", leave=False, disable=not_verbose): File "/home/user/.pyenv/versions/3.7.9/lib/python3.7/site-packages/tqdm/std.py", line 1133, in __iter__ for obj in iterable: File "/app/.cache/huggingface/modules/datasets_modules/datasets/json/9498524fd296a6cca99c66d6c5be507d1c0991f5a814e535b507f4a66096a641/json.py", line 83, in _generate_tables parse_options=self.config.pa_parse_options, File "pyarrow/_json.pyx", line 247, in pyarrow._json.read_json File "pyarrow/error.pxi", line 122, in pyarrow.lib.pyarrow_internal_check_status File "pyarrow/error.pxi", line 84, in pyarrow.lib.check_status pyarrow.lib.ArrowInvalid: straddling object straddles two block boundaries (try to increase block size?) ``` When using only a small portion of the sample file, say first 100 lines, it works perfectly well.. I see that it is the error from pyarrow, but could you give me a hint or possible solutions? #369 describes the same error and #372 claims to have fixed the issue, but I have no clue why I am still getting this one. Thanks in advance!

Currently all datasets are loaded using memory mapping by default in `load_dataset`. However this might not be necessary for small datasets. If a dataset is small enough, then it can be loaded in-memory and: - its memory footprint would be small so it's ok - in-memory computations/queries would be faster - the caching on-disk would be disabled, making computations even faster (no I/O bound because of the disk) - but running the same computation a second time would recompute everything since there would be no cached results on-disk. But this is probably fine since computations would be fast anyway + users should be able to provide a cache filename if needed. Therefore, maybe the default behavior of `load_dataset` should be to load small datasets in-memory and big datasets using memory mapping.

The `cast` operation on a pyarrow Table may create new arrays in memory. This is an issue since users expect memory mapped datasets to not fill up the RAM. To fix that I used `map` to write a new arrow file on disk when cast is used. To make things more convenient I introduced the `arrow` formatting of a dataset, to make it return pyarrow tables instead of python dicts. This way one can use pyarrow transforms directly when using `map`. edit: we'll use the same mechanism for `filter`

# What does this PR do? I added OpenGraph/ Twitter Card support to the docs to create nice social thumbnails. ![Bildschirmfoto 2021-04-07 um 08 36 50](https://user-images.githubusercontent.com/32632186/113821698-bac2ce80-977c-11eb-81aa-d8f16355857e.png) To be able to add these I needed to install `sphinxext-opengraph`. I came across this [issue](https://github.com/readthedocs/readthedocs.org/issues/1758) on the readthedocs repo saying that since someone has built this plugin they are not integrating and providing documentation to it. That's why I added it for creating the documentation. The repository can be found [here](https://github.com/wpilibsuite/sphinxext-opengraph/tree/main). P.S. It seemed that `make style` never ran for `docs/` i hope the changes are okay otherwise I'll revert it.

Hi! In the docs for `cast`, it's noted that `For non-trivial conversion, e.g. string <-> ClassLabel you should use map() to update the Dataset.` Would it be possible to have an example that demonstrates such a string <-> ClassLabel conversion using `map`? Thanks!

I am working with RAG and playing around with different faiss indexes. At the moment I use **index = faiss.index_factory(768, "IVF65536_HNSW32,Flat")**. During the retrieval phase exactly in [this line of retrieval_rag.py](https://github.com/huggingface/transformers/blob/master/src/transformers/models/rag/retrieval_rag.py#L231) an error issue when all retrieved indices are -1. Please refer to the screenshot of a PID worker. ![image](https://user-images.githubusercontent.com/16892570/113782387-37a67600-9786-11eb-9c29-acad661a9648.png) Here, my retrieve batch size is 2 and n_docs is 5. I can solve this by working around np. stack, but I want to ask, why we get an output index of -1. Do you have any idea :) ? Is this a problem of the index, where the faiss can't find any similar vector? Is there documentation on the output index being -1? @lhoestq

OpenSLR (https://openslr.org/) is a site devoted to hosting speech and language resources, such as training corpora for speech recognition, and software related to speech recognition. There are around 80 speech datasets listed in OpenSLR, currently this PR includes only 9 speech datasets SLR41, SLR42, SLR43, SLR44, SLR63, SLR64, SLR65, SLR66 and SLR69 (Javanese, Khmer, Nepali and Sundanese, Malayalam, Marathi, Tamil, Telugu and Catalan). I can add other speech datasets gradually next time.

Today's release of `fsspec` 0.9.0 implied a new release of `s3fs` 0.6.0 but this version breaks the CI (see [here](https://app.circleci.com/pipelines/github/huggingface/datasets/5312/workflows/490f3240-cd1c-4dd1-bb60-b416771c5584/jobs/32734) for example) I'm pinning `fsspec` until this has been resolved

Fixes #2167 Using `eval` is not ideal for security reasons (in web apps I assume), but without it the code would be much more complex IMO. In terms of style, instead of explicitly importing a private member (`_RelativeInstruction`), we can add these imports at the top of the module: ```python from . import arrow_reader # gives us access to ReadInstruction and _RelativeInstruction from . import splits # gives us access to NamedSplit ``` and then define the `eval` globals as follows: ```python {**arrow_reader.__dict__, **splits.__dict__} ```

A minimal reproducible example: ```python >>> from datasets import load_dataset, Dataset >>> dset = load_dataset("sst", split="train") >>> dset.save_to_disk("sst") >>> type(dset.split) <class 'datasets.splits.NamedSplit'> >>> dset = Dataset.load_from_disk("sst") >>> type(dset.split) # NamedSplit expected <class 'str'> ``` It seems like this bug was introduced in #2025.

[ "Hi,\r\n\r\na HF dataset can be converted to a Torch Dataset with a simple wrapper as follows:\r\n```python\r\nfrom torch.utils.data import Dataset\r\n \r\nclass HFDataset(Dataset):\r\n def __init__(self, dset):\r\n self.dset = dset\r\n\r\n def __getitem__(self, idx):\r\n return self.dset[idx]\r\n\r\n def __len__(self):\r\n return len(self.dset)\r\n\r\ntrain_ds = HFDataset(train_ds)\r\n```\r\n@lhoestq Since the Arrow Dataset already provides `__getitem__` and `__len__`, I think we could use the [virtual subclass](https://docs.python.org/3/library/abc.html#abc.ABCMeta.register) mechanism from the `abc` module to elegantly solve this issue. This mechanism would allow the Arrow Dataset to be used in place of the Torch Dataset because the `isinstance(instance of Arrow Dataset, TorchDataset)` check would return True (DeepSpeed has this check [here](https://github.com/microsoft/DeepSpeed/blob/ab5534fc4c0f8ca21ada321f9730d723aa31288b/deepspeed/runtime/engine.py#L823)).\r\n\r\nAnd it requires a minimal change in the `arrow_dataset.py` file:\r\n```python\r\nif config.TORCH_AVAILABLE:\r\n from torch.utils.data import Dataset as TorchDataset\r\n TorchDataset.register(Dataset)\r\n```", "Interesting ! Thanks for sharing this @mariosasko . I like the idea\r\nThis looks like something we should add IMO", "@mariosasko \r\nThx for your code!\r\nIt perfectly works with a small modification for HF NLP dataset:\r\n```\r\noriginal_ds = nlp.load_dataset('scientific_papers', 'arxiv')\r\ntrain_ds = HFDataset(train_ds['train']) # needs splitting\r\n```", "@lhoestq Sadly, from Python 3.7 onwards `torch.utils.data.Dataset` doesn't support the virtual subclass mechanism due to `typing.Generic` type no longer having `abc.ABCMeta` as its metaclass.\r\n\r\nWith that in mind, another option is to remove a direct type check (`isinstance(dataset, torch.utils.data.Dataset)`) in `deepspeed.initalize` and to rewrite the checks in a manner similar to `torch.utils.data.DataLoader` ([link](https://github.com/pytorch/pytorch/blob/b80c6f863f2327c712c478f67c248b94d66b65ac/torch/utils/data/dataloader.py#L197-L239)). This is exactly why the `DataLoader` works with arbitrary objects that provide `__getitem__` and `__len__` (and in our case, the `ArrowDataset`). By doing so, their code wouldn't be any stricter in comparison to the `DataLoader`.\r\n\r\nSo if you agree, I can open an issue in their repo and fix this if they like the idea.", "That makes sense ! Feel free to open an issue on their repo and discuss this idea", "@y-rokutan Hi, now if you install `deepspeed` from master (this feature will be available in the next official release), the code should work without subclassing. Let us know if you still have any issues.", "Worth mentioning that any function that expects a `torch..Dataset` (like `torch..DataLoader`) will fail a mypy-esque typecheck if a `datasets.Dataset` is passed, even though it implements the interface correctly (I think). The virtual subclass idea was a good one- I wonder if there's another workaround given the Generic issue. What we're really talking about is something similar to the structural subtyping semantics that `typing.Protocol` defines. If `torch..DataLoader` accepted anything that supports `__getitem__` and `__len__` methods this would be much easier. Not sure if there's a way to do this without the wrapper from the perspective of `datasets`." ]

Hi, I'm trying to pretraine deep-speed model using HF arxiv dataset like: ``` train_ds = nlp.load_dataset('scientific_papers', 'arxiv') train_ds.set_format( type="torch", columns=["input_ids", "attention_mask", "global_attention_mask", "labels"], ) engine, _, _, _ = deepspeed.initialize( args=args, model=model, model_parameters=[p for p in model.parameters() if p.requires_grad], training_data=train_ds) ``` but deepspeed.initialize accepts torch.utils.data.Dataset only. How can I convert HF-style dataset to torch-style dataset?

Hi Some of the datasets I need like cc100 are very large, and then I wonder if I can download first X samples of the shuffled/unshuffled data without going through first downloading the whole data then sampling? thanks

Hi @lhoestq I am running this code from huggingface transformers https://github.com/huggingface/transformers/blob/master/examples/language-modeling/run_mlm.py to speed up tokenization, since I am running on multiple datasets, I am using data_args.preprocessing_num_workers = 4 with opus100 corpus but this moves on till a point and then this freezes almost for sometime during tokenization steps and then this is back again, overall to me taking more time than normal case, I appreciate your advice on how I can use this option properly to speed up. thanks

NorNE is a manually annotated corpus of named entities which extends the annotation of the existing Norwegian Dependency Treebank. Comprising both of the official standards of written Norwegian (Bokmål and Nynorsk), the corpus contains around 600,000 tokens and annotates a rich set of entity types including persons, organizations, locations, geo-political entities, products, and events, in addition to a class corresponding to nominals derived from names. See #1720.

First of all, I'm sorry if it is a repeated issue or the changes are already in master, I searched and I didn't find anything. I'm using datasets 1.5.0 ![image](https://user-images.githubusercontent.com/37592763/113114369-8f376580-920b-11eb-900d-94365b59f04b.png) As you can see, when I load the dataset, the ClassLabels are ignored, I have to cast the dataset in order to make it work. Code to reproduce: ```python import datasets data_location = "/data/prueba_multiclase" features = datasets.Features( {"texto": datasets.Value("string"), "label": datasets.features.ClassLabel(names=["false", "true"])} ) dataset = datasets.load_dataset( "csv", data_files=data_location, delimiter="\t", features=features ) ``` Dataset I used: [prueba_multiclase.zip](https://github.com/huggingface/datasets/files/6235022/prueba_multiclase.zip) (it has to be unzipped) Thank you! ❤️

This should fix issue #2134 Pickling is limited to <4GiB objects, it's not possible to pickle a big arrow table (for multiprocessing for example). For big tables, we have to write them on disk and only pickle the path to the table.

[ "Hi @marrodion. \r\n\r\nThanks for pointing this out. It would be great to incorporate this metric-specific enhancement.\r\n\r\nAnother possibility would be to require the user to input the scheme as a string `mode=\"strict\", scheme=\"IOB2\"` and then dynamically import the corresponding module using Python `importlib`:\r\n```python\r\nif scheme:\r\n scheme = importlib.import_module(f\"seqeval.scheme.{scheme}\")\r\n```\r\n\r\nFeel free to create a Pull Request to make this contribution." ]

Right now `load_metric("seqeval")` only works in the default mode of evaluation (equivalent to conll evaluation). However, seqeval library [supports](https://github.com/chakki-works/seqeval#support-features) different evaluation schemes (IOB1, IOB2, etc.), which can be plugged in just by supporting additional kwargs in `Seqeval._compute` https://github.com/huggingface/datasets/blob/85cf7ff920c90ca2e12bedca12b36d2a043c3da2/metrics/seqeval/seqeval.py#L109 Things that would be relevant are, for example, supporting `mode="strict", scheme=IOB2` to count only full entity match as a true positive and omit partial matches. The only problem I see is that the spirit of `metrics` seems to not require additional imports from user. `seqeval` only supports schemes as objects, without any string aliases. It can be solved naively with mapping like `{"IOB2": seqeval.scheme.IOB2}`. Or just left as is and require user to explicitly import scheme from `seqeval` if he wants to configure it past the default implementation. If that makes sense, I am happy to implement the change.

This documentation setting will avoid having the return type in a separate line under `Return type`. See e.g. current docs for `Dataset.to_csv`.

Hi, Loading a dataset with `load_dataset` using a split defined via `ReadInstruction` and then saving it to disk results in the following error: `TypeError: Object of type ReadInstruction is not JSON serializable`. Here is the minimal reproducible example: ```python from datasets import load_dataset from datasets import ReadInstruction data_1 = load_dataset( "wikiann", "en", split="validation", ) data_1.save_to_disk("temporary_path_1") print("Save with regular split works.") data_2 = load_dataset( "wikiann", "en", split=ReadInstruction("validation", to=50, unit="%"), ) data_2.save_to_disk("temporary_path_2") ``` and the corresponding output: ``` Reusing dataset wikiann (/xxxxx/.cache/huggingface/datasets/wikiann/en/1.1.0/0b11a6fb31eea02f38ca17610657bfba3206100685283014daceb8da291c3be9) Save with regular split works.

[ "Hi !\r\nIndeed `save_to_disk` doesn't call pickle anymore. Though the `OverflowError` can still appear for in-memory datasets bigger than 4GB.

Using Datasets 1.5.0 on Python 3.7. Recently I've been working on medium to large size datasets (pretokenized raw text sizes from few gigabytes to low tens of gigabytes), and have found out that several preprocessing steps are massively faster when done in memory, and I have the ability to requisition a lot of RAM, so I decided to do these steps completely out of the datasets library. So my workflow is to do several .map() on datasets object, then for the operation which is faster in memory to extract the necessary columns from the dataset and then drop it whole, do the transformation in memory, and then create a fresh Dataset object using .from_dict() or other method. When I then try to call save_to_disk(path) on the dataset, it crashes because of pickling, which appears to be because of using old pickle protocol which doesn't support large files (over 4 GiB). ``` Traceback (most recent call last): File "./tokenize_and_chunkify_in_memory.py", line 80, in <module> main() File "./tokenize_and_chunkify_in_memory.py", line 75, in main tokenize_and_chunkify(config) File "./tokenize_and_chunkify_in_memory.py", line 60, in tokenize_and_chunkify contexts_dataset.save_to_disk(chunked_path) File "/home/cernypro/dev/envs/huggingface_gpu/lib/python3.7/site-packages/datasets/arrow_dataset.py", line 457, in save_to_disk self = pickle.loads(pickle.dumps(self)) OverflowError: cannot serialize a bytes object larger than 4 GiB ``` From what I've seen this issue may be possibly fixed, as the line `self = pickle.loads(pickle.dumps(self))` does not appear to be present in the current state of the repository. To save these datasets to disk, I've resorted to calling .map() over them with `function=None` and specifying the .arrow cache file, and then creating a new dataset using the .from_file() method, which I can then safely save to disk. Additional issue when working with these large in-memory datasets is when using multiprocessing, is again to do with pickling. I've tried to speed up the mapping with function=None by specifying num_proc to the available cpu count, and I again get issues with transferring the dataset, with the following traceback. I am not sure if I should open a separate issue for that. ``` Traceback (most recent call last): File "./tokenize_and_chunkify_in_memory.py", line 94, in <module> main() File "./tokenize_and_chunkify_in_memory.py", line 89, in main tokenize_and_chunkify(config) File "./tokenize_and_chunkify_in_memory.py", line 67, in tokenize_and_chunkify contexts_dataset.map(function=None, cache_file_name=str(output_dir_path / "tmp.arrow"), writer_batch_size=50000, num_proc=config.threads) File "/home/cernypro/dev/envs/huggingface_gpu/lib/python3.7/site-packages/datasets/arrow_dataset.py", line 1485, in map transformed_shards = [r.get() for r in results] File "/home/cernypro/dev/envs/huggingface_gpu/lib/python3.7/site-packages/datasets/arrow_dataset.py", line 1485, in <listcomp> transformed_shards = [r.get() for r in results] File "/home/cernypro/dev/envs/huggingface_gpu/lib/python3.7/site-packages/multiprocess/pool.py", line 657, in get raise self._value File "/home/cernypro/dev/envs/huggingface_gpu/lib/python3.7/site-packages/multiprocess/pool.py", line 431, in _handle_tasks put(task) File "/home/cernypro/dev/envs/huggingface_gpu/lib/python3.7/site-packages/multiprocess/connection.py", line 209, in send self._send_bytes(_ForkingPickler.dumps(obj)) File "/home/cernypro/dev/envs/huggingface_gpu/lib/python3.7/site-packages/multiprocess/reduction.py", line 54, in dumps cls(buf, protocol, *args, **kwds).dump(obj) File "/home/cernypro/dev/envs/huggingface_gpu/lib/python3.7/site-packages/dill/_dill.py", line 454, in dump StockPickler.dump(self, obj) File "/mnt/appl/software/Python/3.7.4-GCCcore-8.3.0/lib/python3.7/pickle.py", line 437, in dump self.save(obj) File "/mnt/appl/software/Python/3.7.4-GCCcore-8.3.0/lib/python3.7/pickle.py", line 504, in save f(self, obj) #

But Python does not care about glyphs: that is the job of the GUI or the terminal; glyphs are what you get with the `print` function (if your terminal is properly configured to display those glyphs).\r\n\r\nYou have more detailed information about Unicode in the Python documentation: https://docs.python.org/3/howto/unicode.html", "thank you so much for the insightful comments.

Hi Wikiann dataset needs to have "spans" columns, which is necessary to be able to use this dataset, but this column is missing from huggingface datasets, could you please have a look? thank you @lhoestq

Hello. I'm trying to pretrain the BERT model with next sentence prediction. Is there any function that supports next sentence prediction like ` TextDatasetForNextSentencePrediction` of `huggingface/transformers` ?

Hi @yjernite, thank you for adding MultiWoZ 2.2 in the huggingface datasets platform. It is beneficial! I spot an error that the order of Dialogue action slot names and values are reversed. https://github.com/huggingface/datasets/blob/649b2c469779bc4221e1b6969aa2496d63eb5953/datasets/multi_woz_v22/multi_woz_v22.py#L251-L262

@yjernite ### Summary I am currently working on the GEM datasets and do not manage to download the wiki_auto_asset_turk data, whereas all other datasets download well with the same code. ### Steps to reproduce Code snippet: from datasets import load_dataset #dataset = load_dataset('gem', 'web_nlg_en') dataset = load_dataset('gem', 'wiki_auto_asset_turk') ``` **Expected behavior:** I expect the dataset to start downloading (download bar appears and progresses toward 100%) **Actual behavior:** Instead of seeing the download bar appearing, nothing happens; the following appears in the console as expected, but nothing more: Downloading: 36.6kB [00:00, 37.2MB/s] Downloading: 41.7kB [00:00, ?B/s] Downloading and preparing dataset gem/wiki_auto_asset_turk (download: 121.37 MiB, generated: 145.69 MiB, post-processed: Unknown size, total: 267.07 MiB) to C:\Users\sfmil\.cache\huggingface\datasets\gem\wiki_auto_asset_turk\1.0.0\f252756d7f1b8f019aac71a1623b2950acfe10d25d956668ac4eae4e93c58b8d... ### Is this a regression? No, it was the first time I was trying to download this dataset (same for the other ones). ### Debug info - Python version: Python 3.8.2 - OS version: Windows 10 Family

To fix this I implemented interpolation search that is pretty effective since datasets usually verifies the condition of evenly distributed chunks (the default chunk size is fixed). ## Benchmark Here is a [benchmark](https://pastebin.com/utEXUqsR) I did on bookcorpus (74M rows): for the current implementation ```python >>> python speed.py Loaded dataset 'bookcorpus', len=74004228, nbytes=4835358766 ========================= Querying unshuffled bookcorpus ========================= Avg access time key=1 : 0.018ms Avg access time key=74004227 : 0.215ms Avg access time key=range(74003204, 74004228) : 1.416ms Avg access time key=RandIter(low=0, high=74004228, size=1024, seed=42): 92.532ms ========================== Querying shuffled bookcorpus ========================== Avg access time key=1 : 0.187ms Avg access time key=74004227 : 6.642ms Avg access time key=range(74003204, 74004228) : 90.941ms Avg access time key=RandIter(low=0, high=74004228, size=1024, seed=42): 3448.456ms ``` for the new one using interpolation search: ```python >>> python speed.py Loaded dataset 'bookcorpus', len=74004228, nbytes=4835358766 ========================= Querying unshuffled bookcorpus ========================= Avg access time key=1 : 0.076ms Avg access time key=74004227 : 0.056ms Avg access time key=range(74003204, 74004228) : 1.807ms Avg access time key=RandIter(low=0, high=74004228, size=1024, seed=42): 24.028ms ========================== Querying shuffled bookcorpus ========================== Avg access time key=1 : 0.061ms Avg access time key=74004227 : 0.058ms Avg access time key=range(74003204, 74004228) : 22.166ms Avg access time key=RandIter(low=0, high=74004228, size=1024, seed=42): 42.757ms ``` The RandIter class is just an iterable of 1024 random indices from 0 to 74004228. Here is also a plot showing the speed improvement depending on the dataset size: ![image](https://user-images.githubusercontent.com/42851186/112673587-32335c80-8e65-11eb-9a0c-58ad774abaec.png) ## Implementation details: - `datasets.table.Table` objects implement interpolation search for the `slice` method - The interpolation search requires to store the offsets of all the chunks of a table. The offsets are stored when the `Table` is initialized. - `datasets.table.Table.slice` returns a `datasets.table.Table` using interpolation search - `datasets.table.Table.fast_slice` returns a `pyarrow.Table` object using interpolation search. This is useful to get a part of a dataset if we don't need the indexing structure for future computations. For example it's used when querying an example as a dictionary. - Now a `Dataset` object is always backed by a `datasets.table.Table` object. If one passes a `pyarrow.Table` to initialize a `Dataset`, then it's converted to a `datasets.table.Table` ## Checklist: - [x] implement interpolation search - [x] use `datasets.table.Table` in `Dataset` objects - [x] update current tests - [x] add tests for interpolation search - [x] comments and docstring - [x] add the benchmark to the CI Fix #1803.

Hi @lhoestq, @yjernite This is a simple Readme parser. All classes specific to different sections can inherit `Section` class, and we can define more attributes in each.

Fixes: https://github.com/huggingface/datasets/issues/2115 - bug fix: using envrion.copy() returns a dict. - using deepcopy(environ) returns an `_environ` object - Changing the datatype of the _environ object can break code, if subsequent libraries perform operations using apis exclusive to the environ object, like `environ.getenv()` for example. Testing: Tested the change on my terminal: ``` >>> import os >>> x = deepcopy(os.environ) >>> y = os.environ >>> x is y False >>> isinstance(x, type(os.environ)) True >>> z = os.environ.copy() >>> isinstance(z, type(os.environ)) False >>> isinstance(z, dict) True ```

[ "Hi,\r\n\r\nthe `_data` attribute is missing due to `MyDataset.__init__` not calling the parent `__init__`. However, I don't think it's a good idea to subclass the `datasets.Dataset` class (e.g. it's kind of dangerous to override `datasets.Dataset.__getitem__`). Instead, it's better to follow the \"association over inheritance\" approach with a simple wrapper class that delegates calls to a wrapped `Dataset` (map, etc.). Btw, the library offers the `datasets.Dataset.from_pandas` class method to directly create a `datasets.Dataset` from the dataframe." ]

In our testing, we noticed that the datasets.map() implementation is modifying the datatype of python os.environ object from '_Environ' to 'dict'. This causes following function calls to fail as follows: ` x = os.environ.get("TEST_ENV_VARIABLE_AFTER_dataset_map", default=None) TypeError: get() takes no keyword arguments ` It looks like the following line in datasets.map implementation introduced this functionality. https://github.com/huggingface/datasets/blob/0cb1ac06acb0df44a1cf4128d03a01865faa2504/src/datasets/arrow_dataset.py#L1421 Here is the test script to reproduce this error. ``` from datasets import load_dataset from transformers import AutoTokenizer import os def test_train(): model_checkpoint = "distilgpt2" datasets = load_dataset('wikitext', 'wikitext-2-raw-v1') tokenizer = AutoTokenizer.from_pretrained(model_checkpoint, use_fast=True) tokenizer.pad_token = tokenizer.eos_token def tokenize_function(examples): y = tokenizer(examples['text'], truncation=True, max_length=64) return y x = os.environ.get("TEST_ENV_VARIABLE_BEFORE_dataset_map", default=None) print(f"Testing environment variable: TEST_ENV_VARIABLE_BEFORE_dataset_map {x}") print(f"Data type of os.environ before datasets.map = {os.environ.__class__.__name__}") datasets.map(tokenize_function, batched=True, num_proc=2, remove_columns=["text"]) print(f"Data type of os.environ after datasets.map = {os.environ.__class__.__name__}") x = os.environ.get("TEST_ENV_VARIABLE_AFTER_dataset_map", default=None) print(f"Testing environment variable: TEST_ENV_VARIABLE_AFTER_dataset_map {x}") if __name__ == "__main__": test_train() ```

When opening an issue, it is not evident for the users how to choose a blank issue template. There is a link at the bottom of all the other issue templates (`Don’t see your issue here? Open a blank issue.`), but this is not very visible for users. This is the reason why many users finally chose the `add-dataset` template instead (this is more visible) for issues that indeed are not requesting the addition of a new dataset. ~~With this PR, the default blank issue template would be as visible as the other templates (as the `add-dataset` template), thus making easier for the users to choose it.~~ With this PR: - more issue templates, besides `add-dataset`, are added: `bug-report` and `feature-request` - the issue template chooser is customized, so that it now includes a link to `Discussions` for questions

Hello, I am trying to load_dataset("wiki_movies") and it gives me this error - `FileNotFoundError: Couldn't find file locally at wiki_movies/wiki_movies.py, or remotely at https://raw.githubusercontent.com/huggingface/datasets/1.1.2/datasets/wiki_movies/wiki_movies.py or https://s3.amazonaws.com/datasets.huggingface.co/datasets/datasets/wiki_movies/wiki_movies.py` Trying to do `python run_mlm.py \ --model_name_or_path roberta-base \ --dataset_name wiki_movies \` also gives the same error. Is this something on my end? From what I can tell, this dataset was re-added by @lhoestq a few months ago. Thank you!

This happens after a `map` operation when `num_proc` is set to `>1`. I tested this by cleaning up the json before running the `map` op on the dataset so it's unlikely it's coming from an earlier concatenation. Example result: ``` "citation": "@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n url = {https://dumps.wikimedia.org}\n}\n\n@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n url = {https://dumps.wikimedia.org}\n}\n\n@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n url = {https://dumps.wikimedia.org}\n}\n\n@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n url = {https://dumps.wikimedia.org}\n}\n\n@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n url = {https://dumps.wikimedia.org}\n}\n\n@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n url = {https://dumps.wikimedia.org}\n}\n\n@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n url = {https://dumps.wikimedia.org}\n}\n\n@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n url = {https://dumps.wikimedia.org}\n}\n\n@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n url = {https://dumps.wikimedia.org}\n}\n\n@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n url = {https://dumps.wikimedia.org}\n}\n\n@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n url = {https://dumps.wikimedia.org}\n}\n\n@ONLINE {wikidump,\n author = {Wikimedia Foundation},\n title = {Wikimedia Downloads},\n ``` @lhoestq and I believe this is happening due to the fields being concatenated `num_proc` times.

I have an extremely large tokenized dataset (24M examples) that loads in a few minutes. However, after adding a column similar to `input_ids` (basically a list of integers) and saving the dataset to disk, the load time goes to >1 hour. I've even tried using `np.uint8` after seeing #1985 but it doesn't seem to be helping (the total size seems to be smaller though). Does anyone know what could be the issue? Or does the casting of that column to `int8` need to happen in the function that writes the arrow table instead of in the `map` where I create the list of integers? Tagging @lhoestq since you seem to be working on these issues and PRs :)

[ "Hi ! We plan to add streaming features in the future.\r\n\r\nThis should allow to load a dataset instantaneously without generating the arrow table. The trade-off is that accessing examples from a streaming dataset must be done in an iterative way, and with an additional (but hopefully minor) overhead.\r\nWhat do you think about this ?\r\n\r\nIf you have ideas or suggestions of what you expect from such features as a user, feel free to share them, this is really valuable to us !", "People mainly want this feature either because it takes too much time too make arrow tables, or they occupy too much memory on the disk. I think both the problem can be solved if we provide arrow tables themselves on datasets hub. Can we do this currently @lhoestq ? \r\n", "@lhoestq I think the ```try_from_hf_gcs``` provide the same functionality. What all datasets are available on HF GCS? Are all the datasets on huggingFace datasets hub are made available on GCS, automatically?", "Only datasets like wikipedia, wiki40b, wiki_dpr and natural questions are available already processed on the HF google storage. This is used to download directly the arrow file instead of building it from the original data files.", "@lhoestq How can we make sure that the data we upload on HuggingFace hub is available in form of preprocessed arrow files ?", "We're still working on this :) This will be available soon\r\nUsers will be able to put their processed arrow files on the Hub", "Hi! You can now use `Dataset.push_to_hub` to store preprocessed files on the Hub.\r\n\r\nAnd to avoid downloading preprocessed files, you can use streaming by setting `streaming=True` in `load_dataset`." ]

[ "Hi,\r\n\r\nthis bug is related to `Dataset.{remove_columns, rename_column, flatten}` not propagating the change to the schema metadata when the info features are updated, so this line is the culprit:\r\n```python\r\ncommon_voice_train = common_voice_train.remove_columns(['client_id', 'up_votes', 'down_votes', 'age', 'gender', 'accent', 'locale', 'segment'])\r\n\r\n``` \r\nThe order is important because the resulting dataset inherits the schema metadata of the first dataset passed to the `concatenate_datasets(...)` function (`pa.concat_tables` [docs](https://arrow.apache.org/docs/python/generated/pyarrow.concat_tables.html)). I'll try to fix this ASAP." ]

Hey, I played around with the `concatenate_datasets(...)` function: https://huggingface.co/docs/datasets/package_reference/main_classes.html?highlight=concatenate_datasets#datasets.concatenate_datasets and noticed that when the order in which the datasets are concatenated changes an error is thrown where it should not IMO. Here is a google colab to reproduce the error: https://colab.research.google.com/drive/17VTFU4KQ735-waWZJjeOHS6yDTfV5ekK?usp=sharing

I updated and clarified the REFreSD [data card](https://github.com/mcmillanmajora/datasets/blob/refresd_card/datasets/refresd/README.md) with information from the Eleftheria's [website](https://elbria.github.io/post/refresd/). I added brief descriptions where the initial card referred to the paper, and I also recreated some of the tables in the paper to show relevant dataset statistics. I'll email Eleftheria to see if she has any comments on the card.

Hi, I'm trying to put together a `datasets.Dataset` to be used with LayoutLM which is available in `transformers`. This model requires as input the bounding boxes of each of the token of a sequence. This is when I realized that `Dataset` does not support multi-dimensional arrays as a value for a column in a row. The following code results in conversion error in pyarrow (`pyarrow.lib.ArrowInvalid: ('Can only convert 1-dimensional array values', 'Conversion failed for column bbox with type object')`) ``` from datasets import Dataset import pandas as pd import numpy as np dataset = pd.DataFrame({ 'bbox': [ np.array([[1,2,3,4],[1,2,3,4],[1,2,3,4]]), np.array([[1,2,3,4],[1,2,3,4],[1,2,3,4]]), np.array([[1,2,3,4],[1,2,3,4],[1,2,3,4]]), np.array([[1,2,3,4],[1,2,3,4],[1,2,3,4]]) ], 'input_ids': [1, 2, 3, 4] }) dataset = Dataset.from_pandas(dataset) ``` Since I wanted to use pytorch for the downstream training task, I also tried a few ways to directly put in a column of 2-D pytorch tensor in a formatted dataset, but I can only have a list of 1-D tensors, or a list of arrays, or a list of lists. ``` import torch from datasets import Dataset import pandas as pd dataset = pd.DataFrame({ 'bbox': [ [[1,2,3,4],[1,2,3,4],[1,2,3,4]], [[1,2,3,4],[1,2,3,4],[1,2,3,4]], [[1,2,3,4],[1,2,3,4],[1,2,3,4]], [[1,2,3,4],[1,2,3,4],[1,2,3,4]] ], 'input_ids': [1, 2, 3, 4] }) dataset = Dataset.from_pandas(dataset) def test(examples): return {'bbbox': torch.Tensor(examples['bbox'])} dataset = dataset.map(test) print(dataset[0]['bbox']) print(dataset[0]['bbbox']) dataset.set_format(type='torch', columns=['input_ids', 'bbox'], output_all_columns=True) print(dataset[0]['bbox']) print(dataset[0]['bbbox']) def test2(examples): return {'bbbox': torch.stack(examples['bbox'])} dataset = dataset.map(test2) print(dataset[0]['bbox']) print(dataset[0]['bbbox']) ``` Is is possible to support n-D arrays/tensors in datasets? It seems that it can also be useful for this [feature request](https://github.com/huggingface/datasets/issues/263).

Hi, I'm trying to follow the ASR example to try Wav2Vec. This is the code that I use for WER calculation: ``` wer = load_metric("wer") print(wer.compute(predictions=result["predicted"], references=result["target"])) ``` However, I receive the following exception: `Traceback (most recent call last): File "/home/diego/IpGlobal/wav2vec/test_wav2vec.py", line 51, in <module> print(wer.compute(predictions=result["predicted"], references=result["target"])) File "/home/diego/miniconda3/envs/wav2vec3.6/lib/python3.6/site-packages/datasets/metric.py", line 403, in compute output = self._compute(predictions=predictions, references=references, **kwargs) File "/home/diego/.cache/huggingface/modules/datasets_modules/metrics/wer/73b2d32b723b7fb8f204d785c00980ae4d937f12a65466f8fdf78706e2951281/wer.py", line 94, in _compute return wer(references, predictions) File "/home/diego/miniconda3/envs/wav2vec3.6/lib/python3.6/site-packages/jiwer/measures.py", line 81, in wer truth, hypothesis, truth_transform, hypothesis_transform, **kwargs File "/home/diego/miniconda3/envs/wav2vec3.6/lib/python3.6/site-packages/jiwer/measures.py", line 192, in compute_measures H, S, D, I = _get_operation_counts(truth, hypothesis) File "/home/diego/miniconda3/envs/wav2vec3.6/lib/python3.6/site-packages/jiwer/measures.py", line 273, in _get_operation_counts editops = Levenshtein.editops(source_string, destination_string) MemoryError` My system has more than 10GB of available RAM.

This PR fixes several `size_categories` in YAML tags and makes them consistent. Additionally, I have added a few more categories after `1M`, up to `1T`. I would like to add that to the streamlit app also. This PR also adds a couple of infos that I found missing. The code for generating this: ```python for dataset in sorted(os.listdir('./datasets/')): if '.' not in dataset and dataset not in ['c4', 'csv', 'downloads', 'cc100', 'ccaligned_multilingual', 'celeb_a', 'chr_en', 'emea', 'glue']: infos = {} stats = {} st = '' with open(f'datasets/{dataset}/README.md') as f: d = f.read() start_dash = d.find('---') + 3 end_dash = d[start_dash:].find('---') + 3 rest_text = d[end_dash + 3:] try: full_yaml = OmegaConf.create(d[start_dash:end_dash]) readme = OmegaConf.to_container(full_yaml['size_categories'], resolve=True) except Exception as e: print(e) continue try: with open(f'datasets/{dataset}/dataset_infos.json') as f: data = json.load(f) except Exception as e: print(e) continue # Skip those without infos. done_set = set([]) num_keys = len(data.keys()) for keys in data: # dataset = load_dataset('opus100', f'{dirs}') total = 0 for split in data[keys]['splits']: total = total + data[keys]['splits'][split]['num_examples'] if total < 1000: st += "- n<1K" + '\n' infos[keys] = ["n<1K"] elif total >= 1000 and total < 10000: infos[keys] = ["1K<n<10K"] elif total >= 10000 and total < 100000: infos[keys] = ["10K<n<100K"] elif total >= 100000 and total < 1000000: infos[keys] = ["100K<n<1M"] elif total >= 1000000 and total < 10000000: infos[keys] = ["1M<n<10M"] elif total >= 10000000 and total < 100000000: infos[keys] = ["10M<n<100M"] elif total >= 100000000 and total < 1000000000: infos[keys] = ["100M<n<1B"] elif total >= 1000000000 and total < 10000000000: infos[keys] = ["1B<n<10B"] elif total >= 10000000000 and total < 100000000000: infos[keys] = ["10B<n<100B"] elif total >= 100000000000 and total < 1000000000000: infos[keys] = ["100B<n<1T"] else: infos[keys] = ["n>1T"] done_set = done_set.union(infos[keys]) if (isinstance(readme, list) and list(infos.values())[0] != readme) or (isinstance(readme, dict) and readme != infos): print('-' * 30) print(done_set) print(f"Changing Full YAML for {dataset}") print(OmegaConf.to_yaml(full_yaml)) if len(done_set) == 1: full_yaml['size_categories'] = list(done_set) else: full_yaml['size_categories'] = dict([(k, v) for k, v in sorted(infos.items(), key=lambda x: x[0])]) full_yaml_string = OmegaConf.to_yaml(full_yaml) print('-' * 30) print(full_yaml_string) inp = input('Do you wish to continue?(Y/N)') if inp == 'Y': with open(f'./datasets/{dataset}/README.md', 'w') as f: f.write('---\n') f.write(full_yaml_string) f.write('---') f.write(rest_text) else: break ``` Note that the lower-bound is inclusive. I'm unsure if this is how it is done in the tagging app. EDIT: It would be great if there was a way to make the task categories consistent too. For this, the streamlit app can look into all the datasets and check for existing categories and show them in the list. This may add some consistency. EDIT: I understand this will not work for cases where only the infos for some of the configs are present, for example: `ccaligned_multingual` has only 5 out of several configs present, and infos has only information about them. Hence, I have skipped a few datasets in the code, if there are more such datasets, then I'll ignore them too.

[ "Hi ! This error happens when you use `map` in batched mode and then your function doesn't return the same number of values per column.\r\n\r\nIndeed since you're using `map` in batched mode, `prepare_validation_features` must take a batch as input (i.e. a dictionary of multiple rows of the dataset), and return a batch.\r\n\r\nHowever it seems like `tokenized_examples` doesn't have the same number of elements in each field.

Hello, I am using the huggingface official question answering example notebook (https://colab.research.google.com/github/huggingface/notebooks/blob/master/examples/question_answering.ipynb). In the prepare_validation_features function, I made some modifications to tokenize a new set of quesions with the original contexts and save them in three different list called candidate_input_dis, candidate_attetion_mask and candidate_token_type_ids. When I try to run the next cell for dataset.map, I got the following error: `ArrowInvalid: Column 1 named candidate_attention_mask expected length 1180 but got length 1178` My code is as follows: ``` def generate_candidate_questions(examples): val_questions = examples["question"] candididate_questions = random.sample(datasets["train"]["question"], len(val_questions)) candididate_questions = [x[:max_length] for x in candididate_questions] return candididate_questions def prepare_validation_features(examples, use_mixing=False): pad_on_right = tokenizer.padding_side == "right" tokenized_examples = tokenizer( examples["question" if pad_on_right else "context"], examples["context" if pad_on_right else "question"], truncation="only_second" if pad_on_right else "only_first", max_length=max_length, stride=doc_stride, return_overflowing_tokens=True, return_offsets_mapping=True, padding="max_length", ) if use_mixing: candidate_questions = generate_candidate_questions(examples) tokenized_candidates = tokenizer( candidate_questions if pad_on_right else examples["context"], examples["context"] if pad_on_right else candidate_questions, truncation="only_second" if pad_on_right else "only_first", max_length=max_length, stride=doc_stride, return_overflowing_tokens=True, return_offsets_mapping=True, padding="max_length", ) sample_mapping = tokenized_examples.pop("overflow_to_sample_mapping") tokenized_examples["example_id"] = [] if use_mixing: tokenized_examples["candidate_input_ids"] = tokenized_candidates["input_ids"] tokenized_examples["candidate_attention_mask"] = tokenized_candidates["attention_mask"] tokenized_examples["candidate_token_type_ids"] = tokenized_candidates["token_type_ids"] for i in range(len(tokenized_examples["input_ids"])): sequence_ids = tokenized_examples.sequence_ids(i) context_index = 1 if pad_on_right else 0 sample_index = sample_mapping[i] tokenized_examples["example_id"].append(examples["id"][sample_index]) tokenized_examples["offset_mapping"][i] = [ (o if sequence_ids[k] == context_index else None) for k, o in enumerate(tokenized_examples["offset_mapping"][i]) ] return tokenized_examples validation_features = datasets["validation"].map( lambda xs: prepare_validation_features(xs, True), batched=True, remove_columns=datasets["validation"].column_names ) ``` I guess this might happen because of the batched=True. I see similar issues in this repo related to arrow table length mismatch error, but in their cases, the numbers vary a lot. In my case, this error always happens when the expected length and unexpected length are very close. Thanks for the help!
