Hello, in the processing stage, I use two operations. The first one : map + filter, is very fast and it uses the full cores, while the socond step is very slow and did not use full cores. Also, there is a significant lag between them. Am I missing something ? ``` raw_datasets = raw_datasets.map(split_func, batched=False, num_proc=args.preprocessing_num_workers, load_from_cache_file=not args.overwrite_cache, desc = "running split para ==>")\ .filter(lambda example: example['text1']!='' and example['text2']!='', num_proc=args.preprocessing_num_workers, desc="filtering ==>") processed_datasets = raw_datasets.map( preprocess_function, batched=True, num_proc=args.preprocessing_num_workers, remove_columns=column_names, load_from_cache_file=not args.overwrite_cache, desc="Running tokenizer on dataset===>", ) ```

## Describe the bug Dataset loads indefinitely after modifying cache path (~/.cache/huggingface) If none of the environment variables are set, this custom dataset loads fine ( json-based dataset with custom dataset load script) ** Update: Transformer modules faces the same issue as well during loading ## A clear and concise description of what the bug is. Issue: - Dataset loading stalls / freezes indefinitely when HF_HOME is changed to a custom directory - No error code, had to terminate the process - There are some files created in the cache directory: ``` custom_cache_dir | -- modules | -- __init__.py | -- datasets_modules | -- __init__.py | -- datasets | -- __init__.py | -- script.py (Dataset loading script) | -- script.lock ``` There's no error nor any logs thrown so I'm out of ideas of how to to debug this. The custom dataset works fine if the default ~/.cache dir is used, but unfortunately it's out of space and we do not have permissions to modify the disk. ## Steps to reproduce the bug What I've tried: - Modifying HF_HOME (https://github.com/huggingface/transformers/issues/8703) - Modifying HF_DATASETS_CACHE (https://huggingface.co/docs/datasets/v1.12.0/cache.html) - Modifying cache_dir param during runtime ```python >>> from datasets import load_dataset >>> dataset = load_dataset('test_dataset', cache_dir='/path/to/new/cache') ``` - Disabling dataset cache ```python >>> from datasets import set_caching_enabled >>> set_caching_enabled(False) ``` ## Expected results Datasets should load / cache as usual with the only exception that cache directory is different ## Actual results Any actions taken above to change the cache directory results in loading indefinitely without terminating. ## Environment info - `transformers` version: 4.18.0.dev0 - Platform: Linux-4.15.0-54-generic-x86_64-with-glibc2.10 - Python version: 3.8.8 - Huggingface_hub version: 0.4.0 - PyTorch version (GPU?): 1.8.1+cu102 (True) - Tensorflow version (GPU?): 2.4.1 (False) - Flax version (CPU?/GPU?/TPU?): not installed (NA) - Jax version: not installed - JaxLib version: not installed - Using GPU in script?: Yes - Using distributed or parallel set-up in script?: No

### Describe the bug I would like to share cache between two machines (a Windows host machine and a WSL instance). 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 - ```

## Adding a Dataset - **Name:** RVL-CDIP - **Description:** The RVL-CDIP (Ryerson Vision Lab Complex Document Information Processing) dataset consists of 400,000 grayscale images in 16 classes, with 25,000 images per class. There are 320,000 training images, 40,000 validation images, and 40,000 test images. The images are sized so their largest dimension does not exceed 1000 pixels. - **Paper:** https://www.cs.cmu.edu/~aharley/icdar15/ - **Data:** https://www.cs.cmu.edu/~aharley/rvl-cdip/ - **Motivation:** I'm currently adding LayoutLMv2 and LayoutXLM to HuggingFace Transformers. LayoutLM (v1) already exists in the library. This dataset has a large value for document image classification (i.e. classifying scanned documents). LayoutLM models obtain SOTA on this dataset, so would be great to directly use it in notebooks. Instructions to add a new dataset can be found [here](https://github.com/huggingface/datasets/blob/master/ADD_NEW_DATASET.md).

## Describe the bug When the cache directory is linked (soft link) to a directory on a NetApp device, the download fails. ## Steps to reproduce the bug ```bash ln -s /path/to/netapp/.cache ~/.cache ``` ```python load_dataset("imdb") ``` ## Expected results Successfully loading IMDB dataset ## Actual results ``` datasets.utils.info_utils.NonMatchingSplitsSizesError: [{'expected': SplitInfo(name='train', num_bytes=33432835, num_examples=25000, dataset_name='imdb'), 'recorded': SplitInfo(name='train', num_bytes=0, num_examples=0, dataset_name='imdb')}, {'expected': SplitInfo(name='test', num_bytes=32650697, num_examples=25000, dataset_name='imdb'), 'recorded': SplitInfo(name='test', num_bytes=659932, num_examples=503, dataset_name='imdb')}, {'expected': SplitInfo(name='unsupervised', num_bytes=67106814, num_examples=50000, dataset_name='imdb'), 'recorded': SplitInfo(name='unsupervised', num_bytes=0, num_examples=0, dataset_name='imdb')}] ``` ## Environment info <!-- You can run the command `datasets-cli env` and copy-and-paste its output below. --> - `datasets` version: 1.1.2 - Platform: Ubuntu - Python version: 3.8 ## Extra notes Stranger yet, trying to debug the phenomenon, I found the range of results to vary a lot without clear direction: - With `cache_dir="/path/to/netapp/.cache"` the same thing happens. - However, when linking `~/netapp/` to `/path/to/netapp` *and* setting `cache_dir="~/netapp/.cache/huggingface/datasets"` - it does work - On the other hand, when linking `~/.cache` to `~/netapp/.cache` without using `cache_dir`, it does work anymore. While I could test it only for a NetApp device, it might have to do with any other mounted FS. Thanks :)

## Describe the bug In `load_dataset_builder()`, `build_kwargs` and `config_kwargs` can contain the same keywords leading to a TypeError("type object got multiple values for keyword argument "xyz"). I ran into this problem with the keyword: `base_path`. It might happen with other kwargs as well. I think a quickfix would be ```python builder_cls = import_main_class(dataset_module.module_path) builder_kwargs = dataset_module.builder_kwargs data_files = builder_kwargs.pop("data_files", data_files) config_name = builder_kwargs.pop("config_name", name) hash = builder_kwargs.pop("hash") base_path = builder_kwargs.pop("base_path") ``` and then pass base_path into `builder_cls`. ## Steps to reproduce the bug ```python from datasets import load_dataset load_dataset("rotten_tomatoes", base_path="./sample_data") ``` ## Expected results The docs state: `**config_kwargs` — Keyword arguments to be passed to the [BuilderConfig](https://huggingface.co/docs/datasets/v2.4.0/en/package_reference/builder_classes#datasets.BuilderConfig) and used in the [DatasetBuilder](https://huggingface.co/docs/datasets/v2.4.0/en/package_reference/builder_classes#datasets.DatasetBuilder). So I would expect to be able to pass the base_path into `load_dataset()`. ## Actual results TypeError("type object got multiple values for keyword argument "base_path"). ## Environment info <!-- You can run the command `datasets-cli env` and copy-and-paste its output below. --> - `datasets` version: 2.4.0 - Platform: macOS-12.5-arm64-arm-64bit - Python version: 3.8.9 - PyArrow version: 9.0.0

Avoid stuck map operation when subprocesses crashes

I've been using Dataset.map() with `num_proc=os.cpu_count()` to leverage multicore processing for my datasets, but from time to time I get stuck processes waiting forever. Apparently, when one of the subprocesses is abruptly killed (OOM killer, segfault, SIGKILL, etc), the main process keeps waiting for the async task sent to that child process to finish. It seems to be easy to reproduce the issue with the following script: ``` import os from datasets import Dataset, Features, Value def do_stuck(item): os.kill(os.getpid(), 9) data = { "col1": list(range(5)), "col2": list(range(5)), } ds = Dataset.from_dict( data, features=Features({ "col1": Value("int64"), "col2": Value("int64"), }), ) print(ds.map(do_stuck, num_proc=4)) ``` This is an old behavior in Python, which apparently was fixed a few years ago in `concurrent.futures.ProcessPoolExecutor` ([ref](https://bugs.python.org/issue9205)), but not in `multiprocessing.pool.Pool` / `multiprocess.pool.Pool`, which is used by `Dataset.map` ([ref](https://bugs.python.org/issue22393)). This PR is an idea to try to detect when a child process gets killed, and raises a `RuntimeError` warning the dataset.map() caller. EDIT: Related proposal for future improvement: https://github.com/huggingface/datasets/discussions/5977

I need to train large-scale mt5 model on large-scale datasets of wikipedia (multiple of them concatenated or other datasets in multiple languages like OPUS), could you help me how I can avoid loading the full data into memory? to make the scripts not related to data size?

I'm training a Swedish Wav2vec2 model on a Linux GPU and having issues that the huggingface cached dataset folder is completely filling up my disk space (I'm training on a dataset of around 500 gb). The cache folder is 500gb (and now my disk space is full). Is there a way to toggle caching or set the caching to be stored on a different device (I have another drive with 4 tb that could hold the caching files). This might not technically be a bug, but I was unsure and I felt that the bug was the closest one.

After upgrading to the 1.0 started seeing errors in my data loading script after enabling multiprocessing. ```python ... ner_ds_dict = ner_ds.train_test_split(test_size=test_pct, shuffle=True, seed=seed) ner_ds_dict["validation"] = ner_ds_dict["test"] rel_ds_dict = rel_ds.train_test_split(test_size=test_pct, shuffle=True, seed=seed) rel_ds_dict["validation"] = rel_ds_dict["test"] return ner_ds_dict, rel_ds_dict ``` The first train_test_split, `ner_ds`/`ner_ds_dict`, returns a `train` and `test` split that are iterable. The second, `rel_ds`/`rel_ds_dict` in this case, returns a Dataset dict that has rows but if selected from or sliced into into returns an empty dictionary. eg `rel_ds_dict['train'][0] == {}` and `rel_ds_dict['train'][0:100] == {}`. Ok I think I know the problem -- the rel_ds was mapped though a mapper with `num_proc=12`. If I remove `num_proc`. The dataset loads. I also see errors with other map and filter functions when `num_proc` is set. ``` Done writing 67 indices in 536 bytes . Done writing 67 indices in 536 bytes .

Datasets.map causes incorrect overflow_to_sample_mapping when used with tokenizers and small batch size

## Describe the bug When using `tokenizer`, we can retrieve the field `overflow_to_sample_mapping`, since long samples will be overflown into multiple token sequences. However, when tokenizing is done via `Dataset.map`, with `n_proc > 1`, the `overflow_to_sample_mapping` field is wrong. This seems to be because each tokenizer only looks at its share of the samples, and maps to the index _within its share_, but then `Dataset.map` collates them together. ## Steps to reproduce the bug 1. Make a dataset of 3 strings. 2. Tokenize via Dataset.map with n_proc = 8 3. Inspect the `overflow_to_sample_mapping` field ## Expected results `[0, 1, 2]` ## Actual results `[0, 0, 0]` Notes: 1. I have not yet extracted a minimal example, but the above works reliably 2. If the dataset is large, I've yet to determine if this bug still happens a. not at all b. always c. on the small, leftover batch at the end.

Following the discussion on Slack and #349, I've updated the hyperpartisan dataset to pull directly from Zenodo rather than manual install, which should make this dataset much more accessible. Many thanks to @johanneskiesel ! Currently doesn't pass `test_load_real_dataset` - I'm using `self.config.name` which is `default` in this test. Might be related to #474

Inspired by the discussion on hashing in https://github.com/huggingface/datasets/issues/3178#issuecomment-959016329, @lhoestq suggested that it would be neat to allow users more control over the hashing process. Specifically, it would be great if users can specify specific hashing functions depending on the **class** of the object. As an example, we found in the linked topic that loaded spaCy models (`Language` objects) have different hashes when `dump`'d, but their byte representation with `Language.to_bytes()` _is_ deterministic. It would therefore be great if we could specify that for `Language` objects, the hasher should hash the objects `to_bytes()` return value instead of the object itself. This PR adds a new, but tiny, dependency to manage the registry, namely [`catalogue`](https://github.com/explosion/catalogue). Two files have been changed (apart from the added dependency in `setup.py`) and one file has been added. **utils.registry** (added) This file defines our custom Registry and builds a registry called "hashers". A Registry is basically dictionary from names (str) to functions. A function can be added to the registry by a decorator, e.g. ```python @hashers.register(spacy.Language) def hash_spacy_language(nlp): return Hasher.hash(nlp.to_bytes()) ``` You'll notice that `spacy.Language` is not a string, even though the registry holds a str->func mapping. To accomplish this with classes in a dynamic way, catalogue.Registry needed to be subclassed and modified as `DatasetsRegistry`. All methods that use a name as an input are now modified so that classes are deterministically converted in strings in such a way that we can later retrieve the actual class from the string (below). **utils.py_utils** (modified) Added two functions to deal with classes and their qualified names, that is, their full descriptive name including the module. On the one hand it allows us to retrieve a string from a given class, e.g. given `Module` class, return `torch.nn.Module` str. Conversly, a function is added to convert such a full qualified name into a class. For instance, given the string `torch.nn.Module`, return the `Module` class. These straightforward methods allow us to interchangeably use classes and strings without any needed user interaction - they can just register a class, and behind the scenes `DatasetsRegistry` converts these to deterministic strings. **fingerprint** (modified) Updated Hasher.hash so that if the object to hash is an instance of a class in the registry, the registered function is used to hash the object instead of the default behavior. To do so we iterate over the registry `hashers` and convert its keys (strings) into classes, and then we can use `isinstance`. ```python # Check if the current object is an instance that is # applicable to the user-defined hashers. If so, hash # with the user-defined function for full_module_name, func in hashers.get_all().items(): registered_cls = get_cls_from_qualname(full_module_name) if isinstance(value, registered_cls): return func(value) ``` **Putting it all together** To test this, you can try the following example with spaCy. First install spaCy from source and checkout a specific commit. ```shell git clone https://github.com/explosion/spaCy.git cd spaCy/ git checkout cab9209c3dfcd1b75dfe5657f10e52c4d847a3cf cd .. git clone https://github.com/BramVanroy/datasets.git cd datasets git checkout registry pip install -e . pip install ../spaCy spacy download en_core_web_sm ``` Now you can run the following script. By default it will use the custom hasher function for the Language object. You can enable the default behavior by commenting out `@hashers.register...`. ```python import spacy from datasets.fingerprint import Hasher from datasets.utils.registry import hashers # Register a function so that when the Hasher encounters a spacy.Language object # it uses this custom function to hash instead of the default @hashers.register(spacy.Language) def hash_spacy_language(nlp): return Hasher.hash(nlp.to_bytes()) def main(): print(hashers.get_all()) nlp = spacy.load("en_core_web_sm") dump1 = Hasher.hash(nlp) nlp = spacy.load("en_core_web_sm") dump2 = Hasher.hash(nlp) print(dump1) # succeeds when using the registered custom function # fails if using the default assert dump1 == dump2 if __name__ == '__main__': main() ``` To do ==== - The above is just a proof-of-concept. I am open to changes/suggestions - Tests still need to be written - We should consider whether we can make `DatasetsRegistry` very restrictive and ONLY allowing classes. That would make testing easier - otherwise we also need to test for other sorts of objects. - Maybe the `hashers` definition is better suited in `fingerprint`? - Documentation/examples need to be updated - Not sure why the logger is not working in `hash()` - `get_cls_from_qualname` might need a fail-safe: is it possible for a full_qualname to not have a module, and if so how do we deal with that?

# What does this PR do? This PR adds the functionality to load and save `datasets` from and to s3. You can save `datasets` with either `Dataset.save_to_disk()` or `DatasetDict.save_to_disk`. You can load `datasets` with either `load_from_disk` or `Dataset.load_from_disk()`, `DatasetDict.load_from_disk()`. Loading `csv` or `json` datasets from s3 is not implemented. To save/load datasets to s3 you either need to provide an `aws_profile`, which is set up on your machine, per default it uses the `default` profile or you have to pass an `aws_access_key_id` and `aws_secret_access_key`. The implementation was done with the `fsspec` and `boto3`. ### Example `aws_profile` : <details> ```python dataset.save_to_disk("s3://moto-mock-s3-bucket/datasets/sdk", aws_profile="hf-sm") load_from_disk("s3://moto-mock-s3-bucket/datasets/sdk", aws_profile="hf-sm") ``` </details> ### Example `aws_access_key_id` and `aws_secret_access_key` : <details> ```python dataset.save_to_disk("s3://moto-mock-s3-bucket/datasets/sdk", aws_access_key_id="fake_access_key", aws_secret_access_key="fake_secret_key" ) load_from_disk("s3://moto-mock-s3-bucket/datasets/sdk", aws_access_key_id="fake_access_key", aws_secret_access_key="fake_secret_key" ) ``` </details> If you want to load a dataset from a public s3 bucket you can pass `anon=True` ### Example `anon=True` : <details> ```python dataset.save_to_disk("s3://moto-mock-s3-bucket/datasets/sdk", aws_profile="hf-sm") load_from_disk("s3://moto-mock-s3-bucketdatasets/sdk",anon=True) ``` </details> ### Full Example ```python import datasets dataset = datasets.load_dataset("imdb") print(f"DatasetDict contains {len(dataset)} datasets") print(f"train Dataset has the size of: {len(dataset['train'])}") dataset.save_to_disk("s3://moto-mock-s3-bucket/datasets/sdk", aws_profile="hf-sm") remote_dataset = datasets.load_from_disk("s3://moto-mock-s3-bucket/datasets/sdk", aws_profile="hf-sm") print(f"DatasetDict contains {len(remote_dataset)} datasets") print(f"train Dataset has the size of: {len(remote_dataset['train'])}") ``` Related to #878 I would also adjust the documentation after the code would be reviewed, as long as I leave the PR in "draft" status. Something that we can consider is renaming the functions and changing the `_disk` maybe to `_filesystem`

## Describe the bug In short, CommonSenseQA implementation is inconsistent with the original dataset. More precisely, we need to: 1. Add the dataset matching "id" field. The current dataset, instead, regenerates monotonically increasing id. 2. The [“question”][“stem”] field is flattened into "question". We should match the original dataset and unflatten it 3. Add the missing "question_concept" field in the question tree node 4. Anything else? Go over the data structure of the newly repaired CommonSenseQA and make sure it matches the original ## Expected results Every data item of the CommonSenseQA should structurally and data-wise match the original CommonSenseQA dataset. ## Actual results TBD ## Environment info - `datasets` version: 2.1.0 - Platform: macOS-10.15.7-x86_64-i386-64bit - Python version: 3.8.13 - PyArrow version: 7.0.0 - Pandas version: 1.4.2

## Describe the bug Only some datasets have a subset (as in `load_dataset(name, subset)`). If you pass an invalid subset, an error should be thrown. ## Steps to reproduce the bug ```python import datasets datasets.load_dataset('rotten_tomatoes', 'asdfasdfa') ``` ## Expected results This should break, since `'asdfasdfa'` isn't a subset of the `rotten_tomatoes` dataset. ## Actual results This API call silently succeeds.

TIMIT Dataset not working with GPU

## Describe the bug I am working trying to use the TIMIT dataset in order to fine-tune Wav2Vec2 model and I am unable to load the "audio" column from the dataset when working with a GPU. I am working on Amazon Sagemaker Studio, on the Python 3 (PyTorch 1.8 Python 3.6 GPU Optimized) environment, with a single ml.g4dn.xlarge instance (corresponds to a Tesla T4 GPU). I don't know if the issue is GPU related or Python environment related because everything works when I work off of the CPU Optimized environment with a non-GPU instance. My code also works on Google Colab with a GPU instance. This issue is blocking because I cannot get the 'audio' column in any way due to this error, which means that I can't pass it to any functions. I later use the dataset.map function and that is where I originally noticed this error. ## Steps to reproduce the bug ```python from datasets import load_dataset timit_train = load_dataset('timit_asr', split='train') print(timit_train['audio']) ``` ## Expected results Expected to see inside the 'audio' column, which contains an 'array' nested field with the array data I actually need. ## Actual results Traceback ``` --------------------------------------------------------------------------- TypeError Traceback (most recent call last) <ipython-input-6-ceeac555e921> in <module> ----> 1 timit_train['audio'] /opt/conda/lib/python3.6/site-packages/datasets/arrow_dataset.py in __getitem__(self, key) 1917 """Can be used to index columns (by string names) or rows (by integer index or iterable of indices or bools).""" 1918 return self._getitem( -> 1919 key, 1920 ) 1921 /opt/conda/lib/python3.6/site-packages/datasets/arrow_dataset.py in _getitem(self, key, decoded, **kwargs) 1902 pa_subtable = query_table(self._data, key, indices=self._indices if self._indices is not None else None) 1903 formatted_output = format_table( -> 1904 pa_subtable, key, formatter=formatter, format_columns=format_columns, output_all_columns=output_all_columns 1905 ) 1906 return formatted_output /opt/conda/lib/python3.6/site-packages/datasets/formatting/formatting.py in format_table(table, key, formatter, format_columns, output_all_columns) 529 python_formatter = PythonFormatter(features=None) 530 if format_columns is None: --> 531 return formatter(pa_table, query_type=query_type) 532 elif query_type == "column": 533 if key in format_columns: /opt/conda/lib/python3.6/site-packages/datasets/formatting/formatting.py in __call__(self, pa_table, query_type) 280 return self.format_row(pa_table) 281 elif query_type == "column": --> 282 return self.format_column(pa_table) 283 elif query_type == "batch": 284 return self.format_batch(pa_table) /opt/conda/lib/python3.6/site-packages/datasets/formatting/formatting.py in format_column(self, pa_table) 315 column = self.python_arrow_extractor().extract_column(pa_table) 316 if self.decoded: --> 317 column = self.python_features_decoder.decode_column(column, pa_table.column_names[0]) 318 return column 319 /opt/conda/lib/python3.6/site-packages/datasets/formatting/formatting.py in decode_column(self, column, column_name) 221 222 def decode_column(self, column: list, column_name: str) -> list: --> 223 return self.features.decode_column(column, column_name) if self.features else column 224 225 def decode_batch(self, batch: dict) -> dict: /opt/conda/lib/python3.6/site-packages/datasets/features/features.py in decode_column(self, column, column_name) 1337 return ( 1338 [self[column_name].decode_example(value) if value is not None else None for value in column] -> 1339 if self._column_requires_decoding[column_name] 1340 else column 1341 ) /opt/conda/lib/python3.6/site-packages/datasets/features/features.py in <listcomp>(.0) 1336 """ 1337 return ( -> 1338 [self[column_name].decode_example(value) if value is not None else None for value in column] 1339 if self._column_requires_decoding[column_name] 1340 else column /opt/conda/lib/python3.6/site-packages/datasets/features/audio.py in decode_example(self, value) 85 dict 86 """ ---> 87 path, file = (value["path"], BytesIO(value["bytes"])) if value["bytes"] is not None else (value["path"], None) 88 if path is None and file is None: 89 raise ValueError(f"An audio sample should have one of 'path' or 'bytes' but both are None in {value}.")

## Describe the bug Ever since today, I have been getting a DuplicatedKeysError while trying to load my dataset from my own script. Error returned when running this line: `dataset = load_dataset('/content/drive/MyDrive/Thesis/Datasets/book_preprocessing/goodreads_maharjan_trimmed_and_nered/goodreadsnered.py')` Note that my script was working fine with earlier versions of the Datasets library. Cannot say with 100% certainty if I have been doing something wrong with my dataset script this whole time or if this is simply a bug with the new version of datasets. ## Steps to reproduce the bug I cannot provide code to reproduce the error as I am working with my own dataset.

The task API is not well adopted in the ecosystem, so this PR deprecates it. The `train_eval_index` is a newer, more flexible solution that should be used instead (I think?). These are the projects that still use the task API : * the image classification example in Transformers: [here](https://github.com/huggingface/transformers/blob/8f76dc8e5aaad58f2df7748b6d6970376f315a9a/examples/pytorch/image-classification/run_image_classification_no_trainer.py#L262) and [here](https://github.com/huggingface/transformers/blob/8f76dc8e5aaad58f2df7748b6d6970376f315a9a/examples/tensorflow/image-classification/run_image_classification.py#L277) * autotrain: [here](https://github.com/huggingface/autotrain-backend/blob/455e274004b56f9377d64db4ab03671508fcc4cd/zeus/zeus/run/utils.py#L666) * api-inference-community: [here](https://github.com/huggingface/api-inference-community/blob/fb8fb29d577a5bf01c82944db745489a6d6ed3d4/manage.py#L64) (but the rest of the code does not call the `resolve_dataset` function) So we need to update these files after the merge. cc @lewtun

Hi I am trying to concatenate a list of huggingface datastes as: ` train_dataset = datasets.concatenate_datasets(train_datasets) ` Here is the `train_datasets` when I print: ``` [Dataset({ features: ['attention_mask', 'idx', 'input_ids', 'label', 'question1', 'question2', 'token_type_ids'], num_rows: 120361 }), Dataset({ features: ['attention_mask', 'idx', 'input_ids', 'label', 'question1', 'question2', 'token_type_ids'], num_rows: 2670 }), Dataset({ features: ['attention_mask', 'idx', 'input_ids', 'label', 'question1', 'question2', 'token_type_ids'], num_rows: 6944 }), Dataset({ features: ['attention_mask', 'idx', 'input_ids', 'label', 'question1', 'question2', 'token_type_ids'], num_rows: 38140 }), Dataset({ features: ['attention_mask', 'idx', 'input_ids', 'label', 'question1', 'question2', 'token_type_ids'], num_rows: 173711 }), Dataset({ features: ['attention_mask', 'idx', 'input_ids', 'label', 'question1', 'question2', 'token_type_ids'], num_rows: 1655 }), Dataset({ features: ['attention_mask', 'idx', 'input_ids', 'label', 'question1', 'question2', 'token_type_ids'], num_rows: 4274 }), Dataset({ features: ['attention_mask', 'idx', 'input_ids', 'label', 'question1', 'question2', 'token_type_ids'], num_rows: 2019 }), Dataset({ features: ['attention_mask', 'idx', 'input_ids', 'label', 'question1', 'question2', 'token_type_ids'], num_rows: 2109 }), Dataset({ features: ['attention_mask', 'idx', 'input_ids', 'label', 'question1', 'question2', 'token_type_ids'], num_rows: 11963 })] ``` I am getting the following error: `AttributeError: 'DatasetDict' object has no attribute 'concatenate_datasets' ` I was wondering if you could help me with this issue, thanks a lot

This should fix the issues with CSV loading experienced in #2153 and #2200. The CSV builder is an ArrowBasedBuilder that had an issue with its ArrowWriter used to write the arrow file from the csv data. The writer wasn't initialized with the features passed by the user. Therefore the writer was inferring the features from the arrow data, discarding the features passed by the user. I fixed that and I updated the tests

Remove implementation-specific kwargs from `file_utils.fsspec_get` and `file_utils.fsspec_head`, instead allowing them to be passed down via `storage_options`. This fixes an issue where s3fs did not recognize a timeout arg as well as fixes an issue mentioned in https://github.com/huggingface/datasets/issues/5281 by allowing users to pass down `storage_options` all the way from `datasets.load_dataset` to support implementation-specific credentials Supports something like the following to provide credentials explicitly instead of relying on boto's methods of locating them ``` load_dataset(..., data_files=["s3://..."], storage_options={"profile": "..."}) ```

Adding simplified Japanese corpus "SNOW T15" and "SNOW T23". They contain original Japanese, simplified Japanese, and original English (the original text is gotten from en-ja translation corpus). Hence, it can be used not only for Japanese simplification but also for en-ja translation. - http://www.jnlp.org/SNOW/T15 - http://www.jnlp.org/SNOW/T23

Running the following code ``` import nlp ds = nlp.load_dataset("trivia_qa", "rc", split="validation[:1%]") # this might take 2.3 min to download but it's cached afterwards... ds.map(lambda x: x, load_from_cache_file=False) ``` triggers a `ArrowInvalid: Could not convert TagMe with type str: converting to null type` error. On the other hand if we remove a certain column of `trivia_qa` which seems responsible for the bug, it works: ``` import nlp ds = nlp.load_dataset("trivia_qa", "rc", split="validation[:1%]") # this might take 2.3 min to download but it's cached afterwards... ds.map(lambda x: x, remove_columns=["entity_pages"], load_from_cache_file=False) ``` . Seems quite hard to debug what's going on here... @lhoestq @thomwolf - do you have a good first guess what the problem could be? **Note** BTW: I think this could be a good test to check that the datasets work correctly: Take a tiny portion of the dataset and check that it can be written correctly.

## Describe the bug At least for 'reclor', 'telugu_books', 'turkish_movie_sentiment', 'ubuntu_dialogs_corpus', 'wikihow', trying to `load_dataset` in streaming mode raises a `TypeError` without any detail about why it fails. ## Steps to reproduce the bug ```python from datasets import load_dataset dataset = load_dataset("reclor", streaming=True) ``` ## Expected results Ideally: raise a specific exception, something like `ManualDownloadError`. Or at least give the reason in the message, as when we load in normal mode: ```python from datasets import load_dataset dataset = load_dataset("reclor") ``` ``` AssertionError: The dataset reclor with config default requires manual data. Please follow the manual download instructions: to use ReClor you need to download it manually. Please go to its homepage (http://whyu.me/reclor/) fill the google form and you will receive a download link and a password to extract it.Please extract all files in one folder and use the path folder in datasets.load_dataset('reclor', data_dir='path/to/folder/folder_name') . Manual data can be loaded with `datasets.load_dataset(reclor, data_dir='<path/to/manual/data>') ``` ## Actual results ``` TypeError: expected str, bytes or os.PathLike object, not NoneType ``` ## Environment info - `datasets` version: 1.11.0 - Platform: macOS-11.5-x86_64-i386-64bit - Python version: 3.8.11 - PyArrow version: 4.0.1

## What's in this PR? This PR solves #5887 since there was a mismatch between the tokenizer and the model used, since the tokenizer was `bert-base-cased` while the model was `distilbert-base-case` both for the PyTorch and TensorFlow alternatives. Since DistilBERT doesn't use/need the `token_type_ids`, the `**batch` was failing, as the batch contained `input_ids`, `attention_mask`, `token_type_ids`, `start_positions` and `end_positions`, and `token_type_ids` was not required. Besides that, at the end `seqeval` was being used to evaluate the model predictions, and just `evaluate` was being installed, so I've also included the `seqeval` installation. Finally, I've re-run everything in Google Colab, and every cell was successfully executed! ## What was done on top of the original PR? Based on the comments from @mariosasko and @stevhliu, I've updated the contents of this PR to also review the `quickstart.mdx` and update what was needed, besides that, we may eventually move the `Overview.ipynb` dataset to `huggingface/notebooks` following @stevhliu suggestions.

**Is your feature request related to a problem? Please describe.** Using batch mapping, we can easily split examples. However, we lack an appropriate option for merging them back together by some key. Consider this example: ```python # features: # { # "example_id": datasets.Value("int32"), # "text": datasets.Value("string") # } ds = datasets.Dataset() def split(examples): sentences = [text.split(".") for text in examples["text"]] return { "example_id": [ example_id for example_id, sents in zip(examples["example_id"], sentences) for _ in sents ], "sentence": [sent for sents in sentences for sent in sents], "sentence_id": [i for sents in sentences for i in range(len(sents))], } split_ds = ds.map(split, batched=True) def process(examples): outputs = some_neural_network_that_works_on_sentences(examples["sentence"]) return {"outputs": outputs} split_ds = split_ds.map(process, batched=True) ``` I have a dataset consisting of texts that I would like to process sentence by sentence in a batched way. Afterwards, I would like to put it back together as it was, merging the outputs together. **Describe the solution you'd like** Ideally, it would look something like this: ```python def join(examples): order = np.argsort(examples["sentence_id"]) text = ".".join(examples["text"][i] for i in order) outputs = [examples["outputs"][i] for i in order] return {"text": text, "outputs": outputs} ds = split_ds.group_by("example_id", join) ``` **Describe alternatives you've considered** Right now, we can do this: ```python def merge(example): meeting_id = example["example_id"] parts = split_ds.filter(lambda x: x["example_id"] == meeting_id).sort("segment_no") return {"outputs": list(parts["outputs"])} ds = ds.map(merge) ``` Of course, we could process the dataset like this: ```python def process(example): outputs = some_neural_network_that_works_on_sentences(example["text"].split(".")) return {"outputs": outputs} ds = ds.map(process, batched=True) ``` However, that does not allow using an arbitrary batch size and may lead to very inefficient use of resources if the batch size is much larger than the number of sentences in one example. I would very much appreciate some kind of group by operator to merge examples based on the value of one column.

Closes #2230 There is currently no verification for the data type and the uniqueness of the keys yielded by the `dataset_builder`. This PR is currently a work in progress with the following goals: - [x] Adding `hash_salt` to `ArrowWriter` so that the keys belonging to different splits have different hash - [x] Add `key` arrtibute to `ArrowWriter.write()` for hashing - [x] Add a hashing class which takes an input key of certain type (`str`/`int`/anything convertible to string) and produces a 128-bit hash using `hashlib.md5` - [x] Creating a function giving a custom error message when non-unique keys are found **[This will take care of type-checking for keys]** - [x] Checking for duplicate keys in `writer.write()` for each batch [**NOTE**: This PR is currently concerned with `GeneratorBasedBuilder` only, for simplification. A subsequent PR will be made in future for `ArrowBasedBuilder`] @lhoestq Thank you for the feedback. It would be great to have your guidance on this!

## Describe the bug When I try to concatenate 2 datasets (10GB each) , the entire data is loaded into memory instead of being written directly to disk. Interestingly, this happens when trying to save the new dataset to disk or concatenating it again. ![image](https://user-images.githubusercontent.com/7063207/116420321-2b21b480-a83e-11eb-9006-8f6ca729fb6f.png) ## Steps to reproduce the bug ```python from datasets import concatenate_datasets, load_from_disk test_sampled_pro = load_from_disk("test_sampled_pro") val_sampled_pro = load_from_disk("val_sampled_pro") big_set = concatenate_datasets([test_sampled_pro, val_sampled_pro]) # Loaded to memory big_set.save_to_disk("big_set") # Loaded to memory big_set = concatenate_datasets([big_set, val_sampled_pro]) ``` ## Expected results The data should be loaded into memory in batches and then saved directly to disk. ## Actual results The entire data set is loaded into the memory and then saved to the hard disk. ## Versions Paste the output of the following code: ```python - Datasets: 1.6.1 - Python: 3.8.8 (default, Apr 13 2021, 19:58:26) [GCC 7.3.0] - Platform: Linux-5.4.72-microsoft-standard-WSL2-x86_64-with-glibc2.10 ```

In Newsph-NLI Dataset (#1192), it fails to access test data. According to the script below, the download manager will download the train data when trying to download the test data. https://github.com/huggingface/datasets/blob/2a2dd6316af2cc7fdf24e4779312e8ee0c7ed98b/datasets/newsph_nli/newsph_nli.py#L71 If you download it according to the script above, you can see that train and test receive the same data as shown below. ```python >>> from datasets import load_dataset >>> newsph_nli = load_dataset(path="./datasets/newsph_nli.py") >>> newsph_nli DatasetDict({ train: Dataset({ features: ['premise', 'hypothesis', 'label'], num_rows: 420000 }) test: Dataset({ features: ['premise', 'hypothesis', 'label'], num_rows: 420000 }) validation: Dataset({ features: ['premise', 'hypothesis', 'label'], num_rows: 90000 }) }) >>> newsph_nli["train"][0] {'hypothesis': 'Ito ang dineklara ni Atty.

#2025 changed the format of `Dataset.cache_files`. Before it was formatted like ```python [{"filename": "path/to/file.arrow", "start": 0, "end": 1337}] ``` and it was changed to ```python ["path/to/file.arrow"] ``` since there's no start/end offsets available anymore. To make this less breaking, I'm setting the format back to a list of dicts: ```python [{"filename": "path/to/file.arrow"}] ```

## Describe the bug Interleaving multiple iterable datasets that use `load_dataset` on streaming mode hangs when passed to `torch.utils.data.DataLoader` with multiple workers. ## Steps to reproduce the bug ```python from datasets import interleave_datasets, load_dataset from torch.utils.data import DataLoader en_dataset = load_dataset('oscar', "unshuffled_deduplicated_en", split='train', streaming=True) fr_dataset = load_dataset('oscar', "unshuffled_deduplicated_fr", split='train', streaming=True) it_dataset = load_dataset('oscar', "unshuffled_deduplicated_it", split='train', streaming=True) de_dataset = load_dataset('oscar', "unshuffled_deduplicated_de", split='train', streaming=True) multilingual_dataset = interleave_datasets([en_dataset, fr_dataset, de_dataset, it_dataset]) multilingual_dataset = multilingual_dataset.with_format('torch') next(iter(multilingual_dataset)) # works fairly fast dataloader = DataLoader(multilingual_dataset, batch_size=8, num_workers=4) for batch in dataloader: print(len(batch)) # prints nothing after 30 min of waiting dataloader = DataLoader(multilingual_dataset, batch_size=8, num_workers=0) for batch in dataloader: print(len(batch)) # prints right away ``` ## Expected results It should be able to iterate the dataset with multiple workers. ## Actual results Prints with results with `next(iter(multilingual_dataset)) ` and `num_workers=0` but it prints nothing with `num_workers=4` or any number above 0. ## Environment info <!-- You can run the command `datasets-cli env` and copy-and-paste its output below. --> - `datasets` version: 2.0.1.dev0 - `pytorch` version: 1.10.0+cu113 - Python version: 3.7 - PyArrow version: 6.0.1

Now you can set `train_size` to the whole dataset size via `train_size = -1` and login writes not `Training the index with the first -1 vectors` but (for example) `Training the index with the first 16123 vectors`. And maybe more than dataset length. Logging will be correct

Fix issue #2276 and hopefully #2134 The recordbatches of the `IndexedTableMixin` used to speed up queries to the table were copied in memory during a table deepcopy. This resulted in `concatenate_datasets`, `load_from_disk` and other methods to always bring the data in memory. I fixed the copy similarly to #2287 and updated the test to make sure it doesn't happen again (added a test for deepcopy + make sure that the immutable arrow objects are passed to the copied table without being copied). The issue was not caught by our tests because the total allocated bytes value in PyArrow isn't updated when deepcopying recordbatches: the copy in memory wasn't detected. This behavior looks like a bug in PyArrow, I'll open a ticket on JIRA. Thanks @samsontmr , @TaskManager91 and @mariosasko for the help

The goal of this PR is to remove duplicated checks in the `map` logic to execute them only once whenever possible (`fn_kwargs`, `input_columns`, ...). Additionally, this PR improves the consistency (to align it with `input_columns`) of the `remove_columns` check by adding support for a single string value, which is then wrapped into a list.

Is there something I did wrong ?

Hi there, I am trying to load a dataset to the Hub. This dataset is a `DatasetDict` composed of various splits. Some splits have a different `Feature` mapping. Locally, the DatasetDict preserves the individual features but if I `push_to_hub` and then `load_dataset`, the features are all the same. Dataset and code to reproduce available [here](https://huggingface.co/datasets/pietrolesci/robust_nli). In short: I have 3 feature mapping ```python Tri_features = Features( { "idx": Value(dtype="int64"), "premise": Value(dtype="string"), "hypothesis": Value(dtype="string"), "label": ClassLabel(num_classes=3, names=["entailment", "neutral", "contradiction"]), } ) Ent_features = Features( { "idx": Value(dtype="int64"), "premise": Value(dtype="string"), "hypothesis": Value(dtype="string"), "label": ClassLabel(num_classes=2, names=["non-entailment", "entailment"]), } ) Con_features = Features( { "idx": Value(dtype="int64"), "premise": Value(dtype="string"), "hypothesis": Value(dtype="string"), "label": ClassLabel(num_classes=2, names=["non-contradiction", "contradiction"]), } ) ``` Then I create different datasets ```python dataset_splits = {} for split in df["split"].unique(): print(split) df_split = df.loc[df["split"] == split].copy() if split in Tri_dataset: df_split["label"] = df_split["label"].map({"entailment": 0, "neutral": 1, "contradiction": 2}) ds = Dataset.from_pandas(df_split, features=Tri_features) elif split in Ent_bin_dataset: df_split["label"] = df_split["label"].map({"non-entailment": 0, "entailment": 1}) ds = Dataset.from_pandas(df_split, features=Ent_features) elif split in Con_bin_dataset: df_split["label"] = df_split["label"].map({"non-contradiction": 0, "contradiction": 1}) ds = Dataset.from_pandas(df_split, features=Con_features) else: print("ERROR:", split) dataset_splits[split] = ds datasets = DatasetDict(dataset_splits) ``` I then push to hub ```python datasets.push_to_hub("pietrolesci/robust_nli", token="<token>") ``` Finally, I load it from the hub ```python datasets_loaded_from_hub = load_dataset("pietrolesci/robust_nli") ``` And I get that ```python datasets["LI_TS"].features != datasets_loaded_from_hub["LI_TS"].features ``` since ```python "label": ClassLabel(num_classes=2, names=["non-contradiction", "contradiction"]) ``` gets remapped to ```python "label": ClassLabel(num_classes=3, names=["entailment", "neutral", "contradiction"]) ```
