Some question about raw dataset download info in the project .

closed

NONE

Hi , i review the code in https://github.com/huggingface/datasets/blob/master/datasets/conll2003/conll2003.py in the _split_generators function is the truly logic of download raw datasets with dl_manager and use Conll2003 cls by use import_main_class in load_dataset function My question is that , with this logic it seems that i can not have the raw dataset download location in variable in downloaded_files in _split_generators. If someone also want use huggingface datasets as raw dataset downloader, how can he retrieve the raw dataset download path from attributes in datasets.dataset_dict.DatasetDict ?

using map on loaded Tokenizer 10x - 100x slower than default Tokenizer?

open

NONE

This could total relate to me misunderstanding particular call functions, but I added words to a GPT2Tokenizer, and saved it to disk (note I'm only showing snippets but I can share more) and the map function ran much slower: ```` def save_tokenizer(original_tokenizer,text,path="simpledata/tokenizer"): words_unique = set(text.split(" ")) for i in words_unique: original_tokenizer.add_tokens(i) original_tokenizer.save_pretrained(path) tokenizer2 = GPT2Tokenizer.from_pretrained(os.path.join(experiment_path,experiment_name,"tokenizer_squad")) train_set_baby=Dataset.from_dict({"text":[train_set["text"][0][0:50]]}) ```` I then applied the dataset map function on a fairly small set of text: ``` %%time train_set_baby = train_set_baby.map(lambda d:tokenizer2(d["text"]),batched=True) ``` The run time for train_set_baby.map was 6 seconds, and the batch itself was 2.6 seconds **100% 1/1 [00:02<00:00, 2.60s/ba] CPU times: user 5.96 s, sys: 36 ms, total: 5.99 s Wall time: 5.99 s** In comparison using (even after adding additional tokens): ` tokenizer = GPT2TokenizerFast.from_pretrained("gpt2")` ``` %%time train_set_baby = train_set_baby.map(lambda d:tokenizer2(d["text"]),batched=True) ``` The time is **100% 1/1 [00:00<00:00, 34.09ba/s] CPU times: user 68.1 ms, sys: 16 µs, total: 68.1 ms Wall time: 62.9 ms** It seems this might relate to the tokenizer save or load function, however, the issue appears to come up when I apply the loaded tokenizer to the map function. I should also add that playing around with the amount of words I add to the tokenizer before I save it to disk and load it into memory appears to impact the time it takes to run the map function.

Add Tweet Eval Dataset

closed

CONTRIBUTOR

Closes Draft PR #1407. Notes: 1. I have excluded `mapping.txt` from the dataset at it only contained the name mappings, which are already present in the ClassLabels. 2. I have also exluded the textual names for the emojis mentioned in the [mapping](https://github.com/cardiffnlp/tweeteval/blob/main/datasets/emoji/mapping.txt). 3. I do not understand @abhishekkrthakur's example generator on #1407. Maybe he was trying to build up on code from some other dataset. Requesting @lhoestq to review.

Add CelebA Dataset

closed

CONTRIBUTOR

Trying to add CelebA Dataset. Need help with testing. Loading examples takes a lot of time so I am unable to generate the `dataset_infos.json` and unable to test. Also, need help with creating `dummy_data.zip`. Additionally, trying to load a few examples using `load_dataset('./datasets/celeb_a',split='train[10:20]')` still loads all the examples (doesn't stop at 10).

Datasets library not suitable for huge text datasets.

closed

NONE

Hi, I'm trying to use datasets library to load a 187GB dataset of pure text, with the intention of building a Language Model. The problem is that from the 187GB it goes to some TB when processed by Datasets. First of all, I think the pre-tokenizing step (with tokenizer.map()) is not really thought for datasets this big, but for fine-tuning datasets, as this process alone takes so much time, usually in expensive machines (due to the need of tpus - gpus) which is not being used for training. It would possibly be more efficient in such cases to tokenize each batch at training time (receive batch - tokenize batch - train with batch), so that the whole time the machine is up it's being used for training. Moreover, the pyarrow objects created from a 187 GB datasets are huge, I mean, we always receive OOM, or No Space left on device errors when only 10-12% of the dataset has been processed, and only that part occupies 2.1TB in disk, which is so many times the disk usage of the pure text (and this doesn't make sense, as tokenized texts should be lighter than pure texts). Any suggestions??

Add OSCAR dataset card

closed

MEMBER

I started adding the dataset card for OSCAR ! For now it's just basic info for all the different configurations in `Dataset Structure`. In particular the Data Splits section tells how may samples there are for each config. The Data Instances section show an example for each config, and it also shows the size in MB. Since the Data Instances section is very long the user has to click to expand the info. I was able to generate it thanks to the tools made by @madlag and @yjernite :D Cc @pjox could you help me with the other sections ?

Add FewRel Dataset

closed

CONTRIBUTOR

Hi, This PR closes this [Card](https://github.com/huggingface/datasets/projects/1#card-53285184) and Issue #1757. I wasn't sure how to add `pid2name` along with the dataset so I added it as a separate configuration. For each (head, tail, tokens) triplet, I have created one example. I have added the dictionary key as `"relation"` in the dataset. Additionally, for `pubmed_unsupervised`, I kept `"relation":""` in the dictionary. Please recommend better alternatives, if any.

Hindi Discourse Analysis (HDA) Dataset consists of textual-entailment pairs. - Each row of the Datasets if made up of 4 columns - Premise, Hypothesis, Label and Topic. - Premise and Hypothesis is written in Hindi while Entailment_Label is in English. - Entailment_label is of 2 types - entailed and not-entailed. - Entailed means that hypotheis can be inferred from premise and not-entailed means vice versa - Dataset can be used to train models for Natural Language Inference tasks in Hindi Language. ### Supported Tasks and Leaderboards - Natural Language Inference for Hindi ### Languages - Dataset is in Hindi ## Dataset Structure - Data is structured in TSV format. - train, test and dev files are in seperate files ### Dataset Instances An example of 'train' looks as follows. ``` {'hypothesis': 'यह एक वर्णनात्मक कथन है।', 'label': 1, 'premise': 'जैसे उस का सारा चेहरा अपना हो और आँखें किसी दूसरे की जो चेहरे पर पपोटों के पीछे महसूर कर दी गईं।', 'topic': 1} ``` ### Data Fields - Each row contatins 4 columns - premise, hypothesis, label and topic. ### Data Splits - Train : 31892 - Valid : 9460 - Test : 9970 ## Dataset Creation - We employ a recasting technique from Poliak et al. (2018a,b) to convert publicly available Hindi Discourse Analysis classification datasets in Hindi and pose them as TE problems - In this recasting process, we build template hypotheses for each class in the label taxonomy - Then, we pair the original annotated sentence with each of the template hypotheses to create TE samples. - For more information on the recasting process, refer to paper https://www.aclweb.org/anthology/2020.aacl-main.71 ### Source Data Source Dataset for the recasting process is the BBC Hindi Headlines Dataset(https://github.com/NirantK/hindi2vec/releases/tag/bbc-hindi-v0.1) #### Initial Data Collection and Normalization - Initial Data was collected by members of MIDAS Lab from Hindi Websites. They crowd sourced the data annotation process and selected two random stories from our corpus and had the three annotators work on them independently and classify each sentence based on the discourse mode. - Please refer to this paper for detailed information: https://www.aclweb.org/anthology/2020.lrec-1.149/ - The Discourse is further classified into "Argumentative" , "Descriptive" , "Dialogic" , "Informative" and "Narrative" - 5 Clases. #### Who are the source language producers? Please refer to this paper for detailed information: https://www.aclweb.org/anthology/2020.lrec-1.149/ ### Annotations #### Annotation process Annotation process has been described in Dataset Creation Section. #### Who are the annotators? Annotation is done automatically by machine and corresponding recasting process. ### Personal and Sensitive Information No Personal and Sensitive Information is mentioned in the Datasets. ## Considerations for Using the Data Pls refer to this paper: https://www.aclweb.org/anthology/2020.aacl-main.71 ### Discussion of Biases No known bias exist in the dataset.

Previous works utilize Natural Language Inference (NLI) to understand the reasoning ability of models, mostly focusing on high resource languages like English. To address scarcity of data in low-resource languages such as Hindi, we use data recasting to create NLI datasets for four existing text classification datasets. Through experiments, we show that our recasted dataset is devoid of statistical irregularities and spurious patterns. We further study the consistency in predictions of the textual entailment models and propose a consistency regulariser to remove pairwise-inconsistencies in predictions. We propose a novel two-step classification method which uses textual-entailment predictions for classification task. We further improve the performance by using a joint-objective for classification and textual entailment. We therefore highlight the benefits of data recasting and improvements on classification performance using our approach with supporting experimental results.", } ``` ### Contributions Thanks to [@avinsit123](https://github.com/avinsit123) for adding this dataset.

Provide better exception message when one of many files results in an exception

closed

I find when I process many files, i.e. ``` train_files = glob.glob('rain*.csv') validation_files = glob.glob(validation*.csv') datasets = load_dataset("csv", data_files=dict(train=train_files, validation=validation_files)) ``` I sometimes encounter an error due to one of the files being misformed (i.e. no data, or a comma in a field that isn't quoted, etc). For example, this is the tail of an exception which I suspect is due to a stray comma. > File "pandas/_libs/parsers.pyx", line 756, in pandas._libs.parsers.TextReader.read > File "pandas/_libs/parsers.pyx", line 783, in pandas._libs.parsers.TextReader._read_low_memory > File "pandas/_libs/parsers.pyx", line 827, in pandas._libs.parsers.TextReader._read_rows > File "pandas/_libs/parsers.pyx", line 814, in pandas._libs.parsers.TextReader._tokenize_rows > File "pandas/_libs/parsers.pyx", line 1951, in pandas._libs.parsers.raise_parser_error > pandas.errors.ParserError: Error tokenizing data.

Add metrics usage examples and tests

closed

MEMBER

All metrics finally have usage examples and proper fast + slow tests :) I added examples of usage for every metric, and I use doctest to make sure they all work as expected. For "slow" metrics such as bert_score or bleurt which require to download + run a transformer model, the download + forward pass are only done in the slow test. In the fast test on the other hand, the download + forward pass are monkey patched. Metrics that need to be installed from github are not added to setup.py because it prevents uploading the `datasets` package to pypi. An additional-test-requirements.txt file is used instead. This file also include `comet` in order to not have to resolve its *impossible* dependencies. Also `comet` is not tested on windows because one of its dependencies (fairseq) can't be installed in the CI for some reason.

I am trying to preprocess any dataset in this package with GPT-2 tokenizer, so I need to structure the datasets as long sequences of text without padding. I've been following a couple of your tutorials and here you can find the script that is failing right at the end https://github.com/LuCeHe/GenericTools/blob/master/KerasTools/lm_preprocessing.py In the last iteration of the last dset.map, it gives the error that I copied in the title. Another issue that I have, if I leave the batch_size set as 1000 in the last .map, I'm afraid it's going to lose most text, so I'm considering setting both writer_batch_size and batch_size to 300 K, but I'm not sure it's the best way to go. Can you help me? Thanks!

Add CCAligned Multilingual Dataset

closed

CONTRIBUTOR

Hello, I'm trying to add [CCAligned Multilingual Dataset](http://www.statmt.org/cc-aligned/). This has the potential to close #1756. This dataset has two types - Document-Pairs, and Sentence-Pairs. The datasets are huge, so I won't be able to test all of them. At the same time, a user might only want to download one particular language and not all. To provide this feature, `load_dataset`'s `**config_kwargs` should allow some random keyword args, in this case -`language_code`. This will be needed before the dataset is downloaded and extracted. I'm expecting the usage to be something like - `load_dataset('ccaligned_multilingual','documents',language_code='en_XX-af_ZA')`. Ofcourse, at a later stage we can provide just two character language codes. This also has an issue where one language has multiple files (`my_MM` and `my_MM_zaw` on the link), but before that the required functionality must be added to `load_dataset`. It would be great if someone could either tell me an alternative way to do this, or point me to where changes need to be made, if any, apart from the `BuilderConfig` definition. Additionally, I believe the tests will also have to be modified if this change is made, since it would not be possible to test for any random keyword arguments. A decent way to go about this would be to provide all the options in a list/dictionary for `language_code` and use that to test the arguments. In essence, this is similar to the pre-trained checkpoint dictionary as `transformers`. That means writing dataset specific tests, or adding something new to dataset generation script to make it easier for everyone to add keyword arguments without having to worry about the tests. Thanks, Gunjan Requesting @lhoestq / @yjernite to review.

Support future datasets

If a dataset is available at the version of the local installation of `datasets` (e.g. 1.2.0), then loading this dataset means loading the script at this version. However when trying to load a dataset that is only available on master, currently users have to specify `script_version="master"` in `load_dataset` to make it work. However we could automatically get the dataset from master instead in this case. I added this feature in this PR. I also added a warning if a dataset is not available at the version of the local installation of `datasets` but is loaded from master: ```python >>> load_dataset("silicone", "dyda_da") Couldn't find file locally at silicone/silicone.py, or remotely at https://raw.githubusercontent.com/huggingface/datasets/1.2.0/datasets/silicone/silicone.py. The file was picked from the master branch on github instead at https://raw.githubusercontent.com/huggingface/datasets/master/datasets/silicone/silicone.py.

Unable to add Multi-label Datasets

CONTRIBUTOR

I am trying to add [CIFAR-100](https://www.cs.toronto.edu/~kriz/cifar.html) dataset. The dataset contains two labels per image - `fine label` and `coarse label`. Using just one label in supervised keys as `supervised_keys=("img", "fine_label")` raises no issue. But trying `supervised_keys=("img", "fine_label","coarse_label")` leads to this error : ```python Traceback (most recent call last): File "test_script.py", line 2, in <module> d = load_dataset('./datasets/cifar100') File "~/datasets/src/datasets/load.py", line 668, in load_dataset **config_kwargs, File "~/datasets/src/datasets/builder.py", line 896, in __init__ super(GeneratorBasedBuilder, self).__init__(*args, **kwargs) File "~/datasets/src/datasets/builder.py", line 247, in __init__ info.update(self._info()) File "~/.cache/huggingface/modules/datasets_modules/datasets/cifar100/61d2489b2d4a4abc34201432541b7380984ec714e290817d9a1ee318e4b74e0f/cifar100.py", line 79, in _info citation=_CITATION, File "<string>", line 19, in __init__ File "~/datasets/src/datasets/info.py", line 136, in __post_init__ self.supervised_keys = SupervisedKeysData(*self.supervised_keys) TypeError: __init__() takes from 1 to 3 positional arguments but 4 were given ``` Is there a way I can fix this? Also, what does adding `supervised_keys` do? Is it necessary? How would I specify `supervised_keys` for a multi-input, multi-label dataset? Thanks, Gunjan

## Add Hateful Memes Dataset - **Name:** Hateful Memes - **Description:** [https://ai.facebook.com/blog/hateful-memes-challenge-and-data-set]( https://ai.facebook.com/blog/hateful-memes-challenge-and-data-set) - **Paper:** [https://arxiv.org/pdf/2005.04790.pdf](https://arxiv.org/pdf/2005.04790.pdf) - **Data:** [This link](https://drivendata-competition-fb-hateful-memes-data.s3.amazonaws.com/XjiOc5ycDBRRNwbhRlgH.zip?AWSAccessKeyId=AKIARVBOBDCY4MWEDJKS&Signature=DaUuGgZWUgDHzEPPbyJ2PhSJ56Q%3D&Expires=1612816874) - **Motivation:** Including multi-modal datasets to 🤗 datasets. I will be adding this dataset. It requires the user to sign an agreement on DrivenData. So, it will be used with a manual download. The issue with this dataset is that the images are of different sizes. The image datasets added so far (CIFAR-10 and MNIST) have a uniform shape throughout. So something like ```python datasets.Array2D(shape=(28, 28), dtype="uint8") ``` won't work for the images. How would I add image features then? I checked `datasets/features.py` but couldn't figure out the appropriate class for this. I'm assuming I would want to avoid re-sizing at all since we want the user to be able to access the original images. Also, in case I want to load only a subset of the data, since the actual data is around 8.8GB, how would that be possible? Thanks, Gunjan

can't pickle SwigPyObject objects when calling dataset.get_nearest_examples from FAISS index

CONTRIBUTOR

So, I have the following instances in my dataset ``` {'question': 'An astronomer observes that a planet rotates faster after a meteorite impact. Which is the most likely effect of this increase in rotation?', 'answer': 'C', 'example_id': 'ARCCH_Mercury_7175875', 'options':[{'option_context': 'One effect of increased amperage in the planetary world (..)', 'option_id': 'A', 'option_text': 'Planetary density will decrease.'}, (...)]} ``` The `options` value is always an list with 4 options, each one is a dict with `option_context`; `option_id` and `option_text`. I would like to overwrite the `option_context` of each instance of my dataset for a dpr result that I am developing.

Querying examples from big datasets is slower than small datasets

closed

MEMBER

After some experiments with bookcorpus I noticed that querying examples from big datasets is slower than small datasets. For example ```python from datasets import load_dataset b1 = load_dataset("bookcorpus", split="train[:1%]") b50 = load_dataset("bookcorpus", split="train[:50%]") b100 = load_dataset("bookcorpus", split="train[:100%]") %timeit _ = b1[-1] # 12.2 µs ± 70.4 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each) %timeit _ = b50[-1] # 92.5 µs ± 1.24 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each) %timeit _ = b100[-1] # 177 µs ± 3.13 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each) ``` It looks like the time to fetch the example increases with the size of the dataset. This is maybe due to the use of the Arrow streaming format to store the data on disk. I guess pyarrow needs to iterate through the file as a stream to find the queried sample. Maybe switching to the Arrow IPC file format could help fixing this issue. Indeed according to the [documentation](https://arrow.apache.org/docs/format/Columnar.html?highlight=arrow1#ipc-file-format), it's identical to the streaming format except that it contains the memory offsets of each sample, which could fix the issue: > We define a “file format” supporting random access that is build with the stream format. The file starts and ends with a magic string ARROW1 (plus padding). What follows in the file is identical to the stream format. At the end of the file, we write a footer containing a redundant copy of the schema (which is a part of the streaming format) plus memory offsets and sizes for each of the data blocks in the file. This enables random access any record batch in the file. See File.fbs for the precise details of the file footer. cc @gaceladri since it can help speed up your training when this one is fixed.

CONTRIBUTOR

Hi, DuoRC SelfRC is one type of the [DuoRC Dataset](https://duorc.github.io/). DuoRC SelfRC is a crowdsourced Abstractive/Extractive Question-Answering dataset based on Wikipedia movie plots. It contains examples that may have answers in the movie plot, synthesized answers which are not present in the movie plot, or no answers. I have also added ParaphraseRC - the other type of DuoRC dataset where questions are based on Wikipedia movie plots and answers are based on corresponding IMDb movie plots. Paper : [https://arxiv.org/abs/1804.07927](https://arxiv.org/abs/1804.07927) I want to add this to 🤗 datasets to make it more accessible to the community. I have added all the details that I could find. Please let me know if anything else is needed from my end. Thanks, Gunjan

Filter on dataset too much slowww

open

NONE

I have a dataset with 50M rows. For pre-processing, I need to tokenize this and filter rows with the large sequence. My tokenization took roughly 12mins. I used `map()` with batch size 1024 and multi-process with 96 processes. When I applied the `filter()` function it is taking too much time. I need to filter sequences based on a boolean column. Below are the variants I tried. 1. filter() with batch size 1024, single process (takes roughly 3 hr) 2. filter() with batch size 1024, 96 processes (takes 5-6 hrs ¯\\\_(ツ)\_/¯) 3. filter() with loading all data in memory, only a single boolean column (never ends). Can someone please help? Below is a sample code for small dataset. ``` from datasets import load_dataset dataset = load_dataset('glue', 'mrpc', split='train') dataset = dataset.map(lambda x: {'flag': random.randint(0,1)==1}) def _amplify(data): return data dataset = dataset.filter(_amplify, batch_size=1024, keep_in_memory=False, input_columns=['flag']) ```

Custom formatting for lazy map + arrow data extraction refactor

closed

MEMBER

Hi ! This PR refactors the way data are extracted from pyarrow tables to extend it to the use of custom formatting functions. While the internal storage of the dataset is always the Apache Arrow format, by setting a specific format on a dataset, you can cast the output of `datasets.Dataset.__getitem__` in NumPy/pandas/PyTorch/TensorFlow, on-the-fly. A specific format can be activated with `datasets.Dataset.set_format`. For example: `dataset.set_format(type='torch', columns=['label'])`. ### What's new: You can now also define your own formatting function that is applied on-the-fly. To do so you can pass your formatting function in the `transform` parameter of `datasets.Dataset.set_format`, and keep `type` to `None`. A formatting function is a callable that takes a batch (as a dict, formatted as python) as input and returns a batch. Here is an example to tokenize and pad tokens on-the-fly when accessing the samples: ```python from datasets import load_dataset from transformers import BertTokenizer tokenizer = BertTokenizer.from_pretrained("bert-base-uncased") def encode(batch): return tokenizer(batch["sentence1"], padding="longest", truncation=True, max_length=512, return_tensors="pt") dataset = load_dataset("glue", "mrpc", split="train") dataset.set_format(transform=encode) dataset.format # {'type': 'custom', 'format_kwargs': {'transform': <function __main__.encode(batch)>}, 'columns': ['idx', 'label', 'sentence1', 'sentence2'], 'output_all_columns': False} dataset[:2] # {'input_ids': tensor([[ 101, 2572, 3217, ... 102]]), 'token_type_ids': tensor([[0, 0, 0, ... 0]]), 'attention_mask': tensor([[1, 1, 1, ... 1]])} ``` Let me know what you think of this API ! We can still change it if we want to. Especially @sgugger since this may be useful when using `datasets` to train models. EDIT: this was changed to `dataset.set_transform(encode)` ------------------- Note: I had to refactor the way data are extracted and formatted from pyarrow tables and I made it more robust and flexible. In particular I modularized it to be able to unit-test it properly. This was very helpful since I detected some bugs in the previous implementation and was able to fix them. Some bugs I found and fixed: - certain slices/ranges were not supported because negative ids were passed to pyarrow - formatting as numpy/torch/tensorflow a column would make it lose its precision information (for example a column as `Value("float32")`) would be returned as a tensor of float64 (default behavior for numpy) - on windows integers formatted as numpy/torch/tensorflow were not always int64 tensors by default but were int32 The unit tests for those are now really extensive :)

Small fix with corrected logging of train vectors

CONTRIBUTOR

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

Not enough disk space (Needed: Unknown size) when caching on a cluster

closed

CONTRIBUTOR

I'm running some experiments where I'm caching datasets on a cluster and accessing it through multiple compute nodes. However, I get an error when loading the cached dataset from the shared disk. The exact error thrown: ```bash >>> load_dataset(dataset, cache_dir="/path/to/cluster/shared/path") OSError: Not enough disk space. Needed: Unknown size (download: Unknown size, generated: Unknown size, post-processed: Unknown size) ``` [`utils.has_sufficient_disk_space`](https://github.com/huggingface/datasets/blob/8a03ab7d123a76ee744304f21ce868c75f411214/src/datasets/utils/py_utils.py#L332) fails on each job because of how the cluster system is designed (`disk_usage(".").free` can't compute on the cluster's shared disk). This is exactly where the error gets thrown: https://github.com/huggingface/datasets/blob/master/src/datasets/builder.py#L502 ```python if not utils.has_sufficient_disk_space(self.info.size_in_bytes or 0, directory=self._cache_dir_root): raise IOError( "Not enough disk space.

Would it be possible to pass a flag to skip this check on disk space?

JSONDecodeError on JSON with multiple lines

closed

CONTRIBUTOR

Hello :), I have been trying to load data using a JSON file. Based on the [docs](https://huggingface.co/docs/datasets/loading_datasets.html#json-files), the following format is supported: ```json {"key1":11, "key2":12, "key3":13} {"key1":21, "key2":22, "key3":23} ``` But, when I try loading a dataset with the same format, I get a JSONDecodeError : `JSONDecodeError: Extra data: line 2 column 1 (char 7142)`. Now, this is expected when using `json` to load a JSON file. But I was wondering if there are any special arguments to pass when using `load_dataset` as the docs suggest that this format is supported. When I convert the JSON file to a list of dictionaries format, I get AttributeError: `AttributeError: 'list' object has no attribute 'keys'`. So, I can't convert them to list of dictionaries either. Please let me know :) Thanks, Gunjan

In the Older version of the Dataset, there are a useful Dataset Explorer that allow user to visualize the examples (training, test and validation) of a particular dataset, it is no longer there in current version. Hope HuggingFace can re-enable the feature that at least allow viewing of the first 20 examples of a particular dataset, or alternatively can extract 20 examples for each datasets and make those part of the Dataset Card Documentation.

Update SciFact URL

closed

CONTRIBUTOR

Hi, I'm following up this [issue](https://github.com/huggingface/datasets/issues/1717). I'm the SciFact dataset creator, and I'm trying to update the SciFact data url in your repo. Thanks again for adding the dataset! Basically, I'd just like to change the `_URL` to `"https://scifact.s3-us-west-2.amazonaws.com/release/latest/data.tar.gz"`. I changed `scifact.py` appropriately and tried running ``` python datasets-cli test datasets/scifact --save_infos --all_configs ``` which I was hoping would update the `dataset_infos.json` for SciFact. But for some reason the code still seems to be looking for the old version of the dataset. Full stack trace below. I've tried to clear all my Huggingface-related caches, and I've `git grep`'d to make sure that the old path to the dataset isn't floating around somewhere. So I'm not sure why this is happening? Can you help me switch the download URL? ``` (datasets) $ python datasets-cli test datasets/scifact --save_infos --all_configs Checking datasets/scifact/scifact.py for additional imports.

Ignore definition line number of functions for caching

closed

MEMBER

As noticed in #1718 , when a function used for processing with `map` is moved inside its python file, then the change of line number causes the caching mechanism to consider it as a different function. Therefore in this case, it recomputes everything. This is because we were not ignoring the line number definition for such functions (even though we're doing it for lambda functions). For example this code currently prints False: ```python from datasets.fingerprint import Hasher # define once def foo(x): return x h = Hasher.hash(foo) # define a second time elsewhere def foo(x): return x print(h == Hasher.hash(foo)) ``` I changed this by ignoring the line number for all functions.

[Question & Bug Report] Can we preprocess a dataset on the fly?

closed

NONE

I know we can use `Datasets.map` to preprocess a dataset, but I'm using it with very large corpus which generates huge cache file (several TB cache from a 400 GB text file). I have no disk large enough to save it. Can we preprocess a dataset on the fly without generating cache? BTW, I tried raising `writer_batch_size`. Seems that argument doesn't have any effect when it's larger than `batch_size`, because you are saving all the batch instantly after it's processed. Please check the following code: https://github.com/huggingface/datasets/blob/0281f9d881f3a55c89aeaa642f1ba23444b64083/src/datasets/arrow_dataset.py#L1532

Hi, I need to load a dataset, I use these commands: ``` from datasets import load_dataset dataset = load_dataset('csv', data_files={'train': 'sick/train.csv', 'test': 'sick/test.csv', 'validation': 'sick/validation.csv'}) print(dataset['validation']) ``` the dataset in sick/train.csv are simple csv files representing the data.

_pickle.PicklingError: Can't pickle typing.Union[str, NoneType]: it's not the same object as typing.Union when calling datasets.map with num_proc=2

It may be a bug of multiprocessing with Datasets, when I disable the multiprocessing by set num_proc to None, everything works fine. The script I use is https://github.com/huggingface/transformers/blob/master/examples/language-modeling/run_mlm_wwm.py Script args: ``` --model_name_or_path ../../../model/chinese-roberta-wwm-ext --train_file /nfs/volume-377-2/bert/data/test/train.txt --output_dir test --do_train --per_device_train_batch_size 2 --gradient_accumulation_steps 2 --learning_rate 1e-4 --max_steps 1000 --warmup_steps 10 --save_steps 1000 --save_total_limit 1 --seed 23333 --max_seq_length 512 --preprocessing_num_workers 2 --cache_dir /nfs/volume-377-2/bert/data/test/cache ``` Where the `/nfs/volume-377-2/bert/data/test/train.txt` is just a toy example with 10000 lines of random string, you should be able to reproduce this error esaily.

Mention kwargs in the Dataset Formatting docs

closed

CONTRIBUTOR

Hi, This was discussed in Issue #1762 where the docs didn't mention that keyword arguments to `datasets.Dataset.set_format()` are allowed. To prevent people from having to check the code/method docs, I just added a couple of lines in the docs. Please let me know your thoughts on this. Thanks, Gunjan @lhoestq

Add Librispeech ASR

closed

MEMBER

This PR adds the librispeech asr dataset: https://www.tensorflow.org/datasets/catalog/librispeech There are 2 configs: "clean" and "other" whereas there are two "train" datasets for "clean", hence the name "train.100" and "train.360". As suggested by @lhoestq, due to the enormous size of the dataset in `.arrow` format, the speech files are not directly prepared to a float32-array, but instead just the path to the array file is stored.

Connection Issues

NONE

Today, I am getting connection issues while loading a dataset and the metric. ``` Traceback (most recent call last): File "src/train.py", line 180, in <module> train_dataset, dev_dataset, test_dataset = create_race_dataset() File "src/train.py", line 130, in create_race_dataset train_dataset = load_dataset("race", "all", split="train") File "/Users/saeed/Desktop/codes/repos/dreamscape-qa/env/lib/python3.7/site-packages/datasets/load.py", line 591, in load_dataset path, script_version=script_version, download_config=download_config, download_mode=download_mode, dataset=True File "/Users/saeed/Desktop/codes/repos/dreamscape-qa/env/lib/python3.7/site-packages/datasets/load.py", line 267, in prepare_module local_path = cached_path(file_path, download_config=download_config) File "/Users/saeed/Desktop/codes/repos/dreamscape-qa/env/lib/python3.7/site-packages/datasets/utils/file_utils.py", line 343, in cached_path max_retries=download_config.max_retries, File "/Users/saeed/Desktop/codes/repos/dreamscape-qa/env/lib/python3.7/site-packages/datasets/utils/file_utils.py", line 617, in get_from_cache raise ConnectionError("Couldn't reach {}".format(url)) ConnectionError: Couldn't reach https://raw.githubusercontent.com/huggingface/datasets/1.2.1/datasets/race/race.py ``` Or ``` Traceback (most recent call last): File "src/train.py", line 105, in <module> rouge = datasets.load_metric("rouge") File "/Users/saeed/Desktop/codes/repos/dreamscape-qa/env/lib/python3.7/site-packages/datasets/load.py", line 500, in load_metric dataset=False, File "/Users/saeed/Desktop/codes/repos/dreamscape-qa/env/lib/python3.7/site-packages/datasets/load.py", line 267, in prepare_module local_path = cached_path(file_path, download_config=download_config) File "/Users/saeed/Desktop/codes/repos/dreamscape-qa/env/lib/python3.7/site-packages/datasets/utils/file_utils.py", line 343, in cached_path max_retries=download_config.max_retries, File "/Users/saeed/Desktop/codes/repos/dreamscape-qa/env/lib/python3.7/site-packages/datasets/utils/file_utils.py", line 617, in get_from_cache raise ConnectionError("Couldn't reach {}".format(url)) ConnectionError: Couldn't reach https://raw.githubusercontent.com/huggingface/datasets/1.2.1/metrics/rouge/rouge.py ```

PAWS-X: Fix csv Dictreader splitting data on quotes

closed

CONTRIBUTOR

```python from datasets import load_dataset # load english paws-x dataset datasets = load_dataset('paws-x', 'en') print(len(datasets['train'])) # outputs 49202 but official dataset has 49401 pairs print(datasets['train'].unique('label')) # outputs [1, 0, -1] but labels are binary [0,1] ``` changed `data = csv.DictReader(f, delimiter="\t")` to `data = csv.DictReader(f, delimiter="\t", quoting=csv.QUOTE_NONE)` in the dataloader to make csv module not split by quotes. The results are as expected for all languages after the change.

Unable to format dataset to CUDA Tensors

closed

CONTRIBUTOR

Hi, I came across this [link](https://huggingface.co/docs/datasets/torch_tensorflow.html) where the docs show show to convert a dataset to a particular format. I see that there is an option to convert it to tensors, but I don't see any option to convert it to CUDA tensors. I tried this, but Dataset doesn't support assignment: ``` columns=['input_ids', 'token_type_ids', 'attention_mask', 'start_positions','end_positions'] samples.set_format(type='torch', columns = columns) for column in columns: samples[column].to(torch.device(self.config.device)) ``` There should be an option to do so, or if there is already a way to do this, please let me know. Thanks, Gunjan
