Cached dataset not loaded

closed

CONTRIBUTOR

## Describe the bug I have a large dataset (common_voice, english) where I use several map and filter functions. Sometimes my cached datasets after specific functions are not loaded. I always use the same arguments, same functions, no seed… ## Steps to reproduce the bug ```python def filter_by_duration(batch): return ( batch["duration"] <= 10 and batch["duration"] >= 1 and len(batch["target_text"]) > 5 ) def prepare_dataset(batch): batch["input_values"] = processor( batch["speech"], sampling_rate=batch["sampling_rate"][0] ).input_values with processor.as_target_processor(): batch["labels"] = processor(batch["target_text"]).input_ids return batch train_dataset = train_dataset.filter( filter_by_duration, remove_columns=["duration"], num_proc=data_args.preprocessing_num_workers, ) # PROBLEM HERE -> below function is reexecuted and cache is not loaded train_dataset = train_dataset.map( prepare_dataset, remove_columns=train_dataset.column_names, batch_size=training_args.per_device_train_batch_size, batched=True, num_proc=data_args.preprocessing_num_workers, ) # Later in script set_caching_enabled(False) # apply map on trained model to eval/test sets ``` ## Expected results The cached dataset should always be reloaded. ## Actual results The function is reexecuted. I have access to cached files `cache-xxxxx.arrow`. Is there a way I can somehow load manually 2 versions and see how the hash was created for debug purposes (to know if it's an issue with dataset or function)? ## Environment info <!-- You can run the command `datasets-cli env` and copy-and-paste its output below. --> - `datasets` version: 1.6.2 - Platform: Linux-5.8.0-45-generic-x86_64-with-glibc2.29 - Python version: 3.8.5 - PyTorch version (GPU?): 1.8.1+cu102 (True) - Tensorflow version (GPU?): not installed (NA) - Using GPU in script?: Yes - Using distributed or parallel set-up in script?: No

.map() function got an unexpected keyword argument 'cache_file_name'

closed

NONE

## Describe the bug I'm trying to save the result of datasets.map() to a specific file, so that I can easily share it among multiple computers without reprocessing the dataset. However, when I try to pass an argument 'cache_file_name' to the .map() function, it throws an error that ".map() function got an unexpected keyword argument 'cache_file_name'". I believe I'm using the latest dataset 1.6.2. Also seems like the document and the actual code indicates there is an argument 'cache_file_name' for the .map() function. Here is the code I use ## Steps to reproduce the bug ```datasets = load_from_disk(dataset_path=my_path) [...] def tokenize_function(examples): return tokenizer(examples[text_column_name]) logger.info("Mapping dataset to tokenized dataset.") tokenized_datasets = datasets.map( tokenize_function, batched=True, num_proc=preprocessing_num_workers, remove_columns=column_names, load_from_cache_file=True, cache_file_name="my_tokenized_file" ) ``` ## Actual results tokenized_datasets = datasets.map( TypeError: map() got an unexpected keyword argument 'cache_file_name' ## Environment info <!-- You can run the command `datasets-cli env` and copy-and-paste its output below. --> - `datasets` version:1.6.2 - Platform:Linux-4.18.0-193.28.1.el8_2.x86_64-x86_64-with-glibc2.10 - Python version:3.8.5 - PyArrow version:3.0.0

Paperswithcode dataset mapping

MEMBER

This is a continuation of https://github.com/huggingface/huggingface_hub/pull/43, encoded directly inside dataset cards. As discussed: - `paperswithcode_id: null` when the dataset doesn't exist on paperswithcode's side. - I've added this new key at the end of the yaml instead of ordering all keys alphabetically as pyyaml's default. No strong opinion on that one though

Free datasets with cache file in temp dir on exit

closed

CONTRIBUTOR

This PR properly cleans up the memory-mapped tables that reference the cache files inside the temp dir. Since the built-in `_finalizer` of `TemporaryDirectory` can't be modified, this PR defines its own `TemporaryDirectory` class that accepts a custom clean-up function. Fixes #2402

Add env variable for `MAX_IN_MEMORY_DATASET_SIZE_IN_BYTES`. This will allow to turn off default behavior: loading in memory (and not caching) small datasets. Fix #2387.

Update text classification template labels in DatasetInfo __post_init__

closed

MEMBER

This PR implements the idea discussed in #2389 to update the `labels` of the `TextClassification` template in the `DatasetInfo.__post_init__`. The main reason for doing so is so avoid duplicating the label definitions in both `DatasetInfo.features` and `DatasetInfo.task_templates`. To avoid storing state in `DatasetInfo.__post_init__`, the current implementation flushes `DatasetInfo.task_templates` before the features are cast in `Dataset.prepare_for_task` (thanks to @mariosasko for this idea!). Here is an example of the current workflow: ```python ds1 = load_dataset("./datasets/emotion/") # cast features and flush templates ds2 = ds1.prepare_for_task("text-classification") assert ds2.info.task_templates is None ``` Note that if users want to pass a `TextClassification` template to `prepare_for_task`, we require them to set `TextClassification.labels` to match the dataset's features corresponding to `label_column`: ```python ds1 = load_dataset("./datasets/emotion/") # TextClassification.labels is None by default => invalid template task = TextClassification(text_column="text", label_column="label") # Raises ValueError ds1.prepare_for_task(task) # Specifying the labels => valid template task = TextClassification(text_column="text", label_column="label", labels=['anger', 'fear', 'joy', 'love', 'sadness', 'surprise']) ds1.prepare_for_task(task) ``` This PR also adds: * New tests + fixed some old tests that weren't testing `assertRaises` properly * A decorator to share docstrings across common functions. This allows us to document `DatasetDict.prepare_for_task` and `Dataset.prepare_for_task` in one place. * Fixes to avoid side-effects from in-place replacements of `DatasetInfo.task_templates` in `DatasetInfo.__post_init__`. Thanks to @lhoestq for figuring this out! * Removal of `FeaturesWithLazyClassLabel` since we now create a new instance of `TextClassification` in `DatasetInfo.__post_init__` and avoid the side-effects first pointed out by @mariosasko ### PR Description from original WIP Hi @yjernite and @lhoestq, here's a first stab at the suggestion discussed in #2389 to update the `labels` of the `TextClassification` template in the `DatasetInfo.__post_init__`. One problem I've spotted is that my current implementation introduces state into the `__post_init__`: * When we call `load_dataset`, `DatasetInfo.features` are the "raw" features without any casting so we can access the column names by the `label_column` specified in `TextClassification` * When we call `Dataset.prepare_for_task` we run into a problem because the `DatasetInfo.features` are first cast into the new schema which triggers a `KeyError` when we update the infos [here](https://github.com/huggingface/datasets/blob/8b2a78520828e0cc13c14a31f413a5395ef25110/src/datasets/arrow_dataset.py#L1959). Here's an explicit example of what I mean with the stack trace appended below: ```python from datasets import load_dataset # this works ds = load_dataset("emotion") # we can verify the task template is correctly set ds["train"].info.task_templates # returns [TextClassification(labels=('sadness', 'joy', 'love', 'anger', 'fear', 'surprise'), text_column='text', label_column='label')] # but this fails because the _post_init__ is looking for the original column names ds.prepare_for_task("text-classification") ``` ``` --------------------------------------------------------------------------- KeyError Traceback (most recent call last) <ipython-input-4-54a43019b319> in <module> ----> 1 ds.prepare_for_task("text-classification") ~/git/datasets/src/datasets/dataset_dict.py in prepare_for_task(self, task) 807 """ 808 self._check_values_type() --> 809 return DatasetDict({k: dataset.prepare_for_task(task=task) for k, dataset in self.items()}) ~/git/datasets/src/datasets/dataset_dict.py in <dictcomp>(.0) 807 """ 808 self._check_values_type() --> 809 return DatasetDict({k: dataset.prepare_for_task(task=task) for k, dataset in self.items()}) ~/git/datasets/src/datasets/arrow_dataset.py in prepare_for_task(self, task) 1421 dataset = self.remove_columns(columns_to_drop) 1422 dataset = dataset.rename_columns(column_mapping) -> 1423 dataset = dataset.cast(features=template.features) 1424 return dataset 1425 ~/git/datasets/src/datasets/arrow_dataset.py in cast(self, features, batch_size, keep_in_memory, load_from_cache_file, cache_file_name, writer_batch_size, num_proc) 970 format = self.format 971 dataset = self.with_format("arrow") --> 972 dataset = dataset.map( 973 lambda t: t.cast(schema), 974 batched=True, ~/git/datasets/src/datasets/arrow_dataset.py in map(self, function, with_indices, input_columns, batched, batch_size, drop_last_batch, remove_columns, keep_in_memory, load_from_cache_file, cache_file_name, writer_batch_size, features, disable_nullable, fn_kwargs, num_proc, suffix_template, new_fingerprint) 1583 1584 if num_proc is None or num_proc == 1: -> 1585 return self._map_single( 1586 function=function, 1587 with_indices=with_indices, ~/git/datasets/src/datasets/arrow_dataset.py in wrapper(*args, **kwargs) 173 } 174 # apply actual function --> 175 out: Union["Dataset", "DatasetDict"] = func(self, *args, **kwargs) 176 datasets: List["Dataset"] = list(out.values()) if isinstance(out, dict) else [out] 177 # re-apply format to the output ~/git/datasets/src/datasets/fingerprint.py in wrapper(*args, **kwargs) 338 # Call actual function 339 --> 340 out = func(self, *args, **kwargs) 341 342 # Update fingerprint of in-place transforms + update in-place history of transforms ~/git/datasets/src/datasets/arrow_dataset.py in _map_single(self, function, with_indices, input_columns, batched, batch_size, drop_last_batch, remove_columns, keep_in_memory, load_from_cache_file, cache_file_name, writer_batch_size, features, disable_nullable, fn_kwargs, new_fingerprint, rank, offset) 1959 if update_data: 1960 # Create new Dataset from buffer or file -> 1961 info = self.info.copy() 1962 info.features = writer._features 1963 if buf_writer is None: ~/git/datasets/src/datasets/info.py in copy(self) 274 275 def copy(self) -> "DatasetInfo": --> 276 return self.__class__(**{k: copy.deepcopy(v) for k, v in self.__dict__.items()}) 277 278 ~/git/datasets/src/datasets/info.py in __init__(self, description, citation, homepage, license, features, post_processed, supervised_keys, task_templates, builder_name, config_name, version, splits, download_checksums, download_size, post_processing_size, dataset_size, size_in_bytes) ~/git/datasets/src/datasets/info.py in __post_init__(self) 174 # The reason is that Dataset.prepare_for_task calls Dataset.cast which converts the 175 # DatasetInfo.features to the new schema and thus template.label_column is no longer a valid key --> 176 object.__setattr__(template, "labels", tuple(self.features[template.label_column].names)) 177 template.label_schema["labels"] = ClassLabel(names=template.labels) 178 self.task_templates[idx] = template KeyError: 'label' ``` What do you think? I did this a bit quickly, so maybe I'm overlooking something obvious :) One thing would be to only update the labels of the task template on load, but this seems a bit hacky IMO

Missing original answers in kilt-TriviaQA

closed

CONTRIBUTOR

I previously opened an issue at https://github.com/facebookresearch/KILT/issues/42 but from the answer of @fabiopetroni it seems that the problem comes from HF-datasets ## Describe the bug The `answer` field in kilt-TriviaQA, e.g. `kilt_tasks['train_triviaqa'][0]['output']['answer']` contains a list of alternative answer which are accepted for the question. However it'd be nice to know the original answer to the question (the only fields in `output` are `'answer', 'meta', 'provenance'`) ## How to fix It can be fixed by retrieving the original answer from the original TriviaQA (e.g. `trivia_qa['train'][0]['answer']['value']`), perhaps at the same place as here where one retrieves the questions https://github.com/huggingface/datasets/blob/master/datasets/kilt_tasks/README.md#loading-the-kilt-knowledge-source-and-task-data cc @yjernite who previously answered to an issue about KILT and TriviaQA :)

Incorrect URLs for some datasets

## Describe the bug It seems that the URLs for the following datasets are invalid: - [ ] `bn_hate_speech` has been renamed: https://github.com/rezacsedu/Bengali-Hate-Speech-Dataset/commit/c67ecfc4184911e12814f6b36901f9828df8a63a - [ ] `covid_tweets_japanese` has been renamed: http://www.db.info.gifu-u.ac.jp/covid-19-twitter-dataset/ As a result we can no longer load these datasets using `load_dataset`. The simple fix is to rename the URL in the dataset script - will do this asap. ## Steps to reproduce the bug ```python from datasets import load_dataset # pick one of the datasets from the list above ds = load_dataset("bn_hate_speech") ``` ## Expected results Dataset loads without error. ## Actual results ``` Downloading: 3.36kB [00:00, 1.07MB/s] Downloading: 2.03kB [00:00, 678kB/s] Using custom data configuration default Downloading and preparing dataset bn_hate_speech/default (download: 951.48 KiB, generated: 949.84 KiB, post-processed: Unknown size, total: 1.86 MiB) to /Users/lewtun/.cache/huggingface/datasets/bn_hate_speech/default/0.0.0/a2dc726e511a2177523301bcad196af05d4d8a2cff30d2769ba8aacc1f5fdb5c...

Accessing Arrow dataset cache_files

## Describe the bug In datasets 1.5.0 the following code snippet would have printed the cache_files: ``` train_data = load_dataset('conll2003', split='train', cache_dir='data') print(train_data.cache_files[0]['filename']) ``` However, in the newest release (1.6.1), it prints an empty list. I also tried loading the dataset with `keep_in_memory=True` argument but still `cache_files` is empty. Was wondering if this is a bug or I need to pass additional arguments so I can access the cache_files.

Improves the code quality of the `TaskTemplate` dataclasses. Changes: * replaces `return NotImplemented` with raise `NotImplementedError` * replaces `sorted` with `len` in the uniqueness check * defines `label2id` and `id2label` in the `TextClassification` template as properties * replaces the `object.__setattr__(self, attr, value)` syntax with (IMO nicer) `self.__dict__[attr] = value`

Dataset Streaming

closed

MEMBER

# Dataset Streaming ## API Current API is ```python from datasets import load_dataset # Load an IterableDataset without downloading data snli = load_dataset("snli", streaming=True) # Access examples by streaming data print(next(iter(snli["train"]))) # {'premise': 'A person on a horse jumps over a broken down airplane.', # 'hypothesis': 'A person is training his horse for a competition.', # 'label': 1} ``` I already implemented a few methods: - IterableDataset.map: apply transforms on-the-fly to the examples - IterableDataset.shuffle: shuffle the data _a la_ TFDS, i.e. with a shuffling buffer - IterableDataset.with_format: set the format to `"torch"` to get a `torch.utils.data.IterableDataset` - merge_datasets: merge two iterable datasets by alternating one or the other (you can specify the probabilities) I would love to have your opinion on the API design :) ## Implementation details ### Streaming Data streaming is done using `fsspec` which has nice caching features. To make dataset streaming work I extend the `open` function of dataset scripts to support opening remote files without downloading them entirely. It also works with remote compressed archives (currently only zip is supported): ```python # Get a file-like object by streaming data from a remote file open("https://github.com/davidsbatista/NER-datasets/raw/master/CONLL2003/train.txt") # Get a file-like object by streaming data from a remote compressed archive by using the hop separator "::" open("zip://snli_1.0_train.txt::https://nlp.stanford.edu/projects/snli/snli_1.0.zip") ``` I also extend the `os.path.join` function to support navigation in remote compressed archives, since it has to deal with the `"::"` separator. This separator is used by `fsspec`. Finally I also added a retry mechanism in case the connection fails during data streaming. ### Transforms An IterableDataset wraps an ExamplesIterable instance. There are different subclasses depending on the transforms we want to apply: - ExamplesIterable: the basic one - MappedExamplesIterable: an iterable with a `map` function applied on the fly - BufferShuffledExamplesIterable: an iterable with a shuffling buffer - CyclingMultiSourcesExamplesIterable: alternates between several ExamplesIterable - RandomlyCyclingMultiSourcesExamplesIterable: randomly alternates between several ExamplesIterable ### DatasetBuilder I use the same builders as usual. I just added a new method `_get_examples_iterable_for_split` to get an ExamplesIterable for a given split. Currently only the GeneratorBasedBuilder and the ArrowBasedBuilder implement it. The BeamBasedBuilder doesn't implement it yet. It means that datasets like wikipedia and natural_questions can't be loaded as IterableDataset for now. ## Other details <S>I may have to do some changes in many dataset script to use `download` instead of `download_and_extract` when extraction is not needed. This will avoid errors for streaming.</s> EDIT: Actually I just check for the extension of the file to do extraction only if needed. EDIT2: It's not possible to stream from .tar.gz files without downloading the file completely. For now I raise an error if one want to get a streaming dataset based on .tar.gz files. ## TODO usual stuff: - [x] make streaming dependency "aiohttp" optional: `pip install datasets[streaming]` - [x] tests - [x] docs

I'm trying to load a local dataset with the code below ``` ds = datasets.load_dataset('my_script.py', data_files='corpus.txt', data_dir='/data/dir', cache_dir='.') ``` But internally a BuilderConfig is created, which tries to use getmtime on the data_files string, without using data_dir.

Json loader fails if user-specified features don't match the json data fields order

closed

MEMBER

If you do ```python dataset = load_dataset("json", data_files=data_files, features=features) ``` Then depending on the order of the features in the json data field it fails: ```python [...] ~/Desktop/hf/datasets/src/datasets/packaged_modules/json/json.py in _generate_tables(self, files) 94 if self.config.schema: 95 # Cast allows str <-> int/float, while parse_option explicit_schema does NOT ---> 96 pa_table = pa_table.cast(self.config.schema) 97 yield i, pa_table [...] ValueError: Target schema's field names are not matching the table's field names: ['tokens', 'ner_tags'], ['ner_tags', 'tokens'] ``` This is because one must first re-order the columns of the table to match the `self.config.schema` before calling cast. One way to fix the `cast` would be to replace it with: ```python # reorder the arrays if necessary + cast to schema # we can't simply use .cast here because we may need to change the order of the columns pa_table = pa.Table.from_arrays([pa_table[name] for name in schema.names], schema=schema) ```

Missing ClassLabel encoding in Json loader

closed

MEMBER

Currently if you want to load a json dataset this way ```python dataset = load_dataset("json", data_files=data_files, features=features) ``` Then if your features has ClassLabel types and if your json data needs class label encoding (i.e. if the labels in the json files are strings and not integers), then it would fail: ```python [...] ~/Desktop/hf/datasets/src/datasets/packaged_modules/json/json.py in _generate_tables(self, files) 94 if self.config.schema: 95 # Cast allows str <-> int/float, while parse_option explicit_schema does NOT ---> 96 pa_table = pa_table.cast(self.config.schema) 97 yield i, pa_table [...] ArrowInvalid: Failed to parse string: 'O' as a scalar of type int64 ``` This is because it just tries to cast the string data to integers, without applying the mapping str->int first The current workaround is to do instead ```python dataset = load_dataset("json", data_files=data_files) dataset = dataset.map(features.encode_example, features=features) ```

Adding Microsoft CodeXGlue Datasets

CONTRIBUTOR

Hi there, this is a new pull request to get the CodeXGlue datasets into the awesome HF datasets lib. Most of the work has been done in this PR #997 by the awesome @madlag. However, that PR has been stale for a while now and so I spoke with @lhoestq about finishing up the final mile and so he told me to open a new PR with the final changes :smile:. I believe I've met all of the changes still left in the old PR to do, except for the change to the languages. I believe the READMEs should include the different programming languages used rather than just using the tag "code" as when searching for datasets, SE researchers may specifically be looking only for what type of programming language and so being able to quickly filter will be very valuable. Let me know what you think of that or if you still believe it should be the "code" tag @lhoestq.

Fixes #2350 In some cases, Faiss GPU index objects do not have neither "device" nor "getDevice". Possibly this happens when some part of the index is computed on CPU. In particular, this would happen with the index `OPQ16_128,IVF512,PQ32` (issue #2350). I did check it, but it is likely that `OPQ` or `PQ` transforms cause it. I propose, instead of using the index object to get the device, to infer it form the `FaissIndex.device` field as it is done in `.add_vectors`. Here we assume that `.device` always corresponds to the index placement and it seems reasonable.

[Question] How to move and reuse preprocessed dataset?

closed

NONE

Hi, I am training a gpt-2 from scratch using run_clm.py. I want to move and reuse the preprocessed dataset (It take 2 hour to preprocess), I tried to : copy path_to_cache_dir/datasets to new_cache_dir/datasets set export HF_DATASETS_CACHE="new_cache_dir/" but the program still re-preprocess the whole dataset without loading cache. I also tried to torch.save(lm_datasets, fw), but the saved file is only 14M. What is the proper way to do this?
