## Describe the bug AutoTokenizer hash value got change after datasets.map ## Steps to reproduce the bug 1. trash huggingface datasets cache 2. run the following code: ```python from transformers import AutoTokenizer, BertTokenizer from datasets import load_dataset from datasets.fingerprint import Hasher tokenizer = AutoTokenizer.from_pretrained('bert-base-uncased') def tokenize_function(example): return tokenizer(example["sentence1"], example["sentence2"], truncation=True) raw_datasets = load_dataset("glue", "mrpc") print(Hasher.hash(tokenize_function)) print(Hasher.hash(tokenizer)) tokenized_datasets = raw_datasets.map(tokenize_function, batched=True) print(Hasher.hash(tokenize_function)) print(Hasher.hash(tokenizer)) ``` got ``` Reusing dataset glue (/home1/wts/.cache/huggingface/datasets/glue/mrpc/1.0.0/dacbe3125aa31d7f70367a07a8a9e72a5a0bfeb5fc42e75c9db75b96da6053ad) 100%|███████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████| 3/3 [00:00<00:00, 1112.35it/s] f4976bb4694ebc51 3fca35a1fd4a1251 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████| 4/4 [00:00<00:00, 6.96ba/s] 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████| 1/1 [00:00<00:00, 15.25ba/s] 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████| 2/2 [00:00<00:00, 5.81ba/s] d32837619b7d7d01 5fd925c82edd62b6 ``` 3. run raw_datasets.map(tokenize_function, batched=True) again and see some dataset are not using cache. ## Expected results `AutoTokenizer` work like specific Tokenizer (The hash value don't change after map): ```python from transformers import AutoTokenizer, BertTokenizer from datasets import load_dataset from datasets.fingerprint import Hasher tokenizer = BertTokenizer.from_pretrained('bert-base-uncased') def tokenize_function(example): return tokenizer(example["sentence1"], example["sentence2"], truncation=True) raw_datasets = load_dataset("glue", "mrpc") print(Hasher.hash(tokenize_function)) print(Hasher.hash(tokenizer)) tokenized_datasets = raw_datasets.map(tokenize_function, batched=True) print(Hasher.hash(tokenize_function)) print(Hasher.hash(tokenizer)) ``` ``` Reusing dataset glue (/home1/wts/.cache/huggingface/datasets/glue/mrpc/1.0.0/dacbe3125aa31d7f70367a07a8a9e72a5a0bfeb5fc42e75c9db75b96da6053ad) 100%|███████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████| 3/3 [00:00<00:00, 1091.22it/s] 46d4b31f54153fc7 5b8771afd8d43888 Loading cached processed dataset at /home1/wts/.cache/huggingface/datasets/glue/mrpc/1.0.0/dacbe3125aa31d7f70367a07a8a9e72a5a0bfeb5fc42e75c9db75b96da6053ad/cache-6b07ff82ae9d5c51.arrow Loading cached processed dataset at /home1/wts/.cache/huggingface/datasets/glue/mrpc/1.0.0/dacbe3125aa31d7f70367a07a8a9e72a5a0bfeb5fc42e75c9db75b96da6053ad/cache-af738a6d84f3864b.arrow Loading cached processed dataset at /home1/wts/.cache/huggingface/datasets/glue/mrpc/1.0.0/dacbe3125aa31d7f70367a07a8a9e72a5a0bfeb5fc42e75c9db75b96da6053ad/cache-531d2a603ba713c1.arrow 46d4b31f54153fc7 5b8771afd8d43888 ``` ## Environment info - `datasets` version: 1.18.0 - Platform: Linux-5.4.0-91-generic-x86_64-with-glibc2.27 - Python version: 3.9.7 - PyArrow version: 6.0.1

[TypeError: Couldn't cast array of type] Cannot load dataset in v1.18

open

MEMBER

## Describe the bug I am trying to load the [`GEM/RiSAWOZ` dataset](https://huggingface.co/datasets/GEM/RiSAWOZ) in `datasets` v1.18.1 and am running into a type error when casting the features. The strange thing is that I can load the dataset with v1.17.0. Note that the error is also present if I install from `master` too. As far as I can tell, the dataset loading script is correct and the problematic features [here](https://huggingface.co/datasets/GEM/RiSAWOZ/blob/main/RiSAWOZ.py#L237) also look fine to me. ## Steps to reproduce the bug ```python from datasets import load_dataset dset = load_dataset("GEM/RiSAWOZ") ``` ## Expected results I can load the dataset without error. ## Actual results

Dataset.shuffle(seed=None) gives fixed row permutation

open

NONE

## Describe the bug Repeated attempts to `shuffle` a dataset without specifying a seed give the same results. ## Steps to reproduce the bug ```python import datasets # Some toy example data = datasets.Dataset.from_dict( {"feature": [1, 2, 3, 4, 5], "label": ["a", "b", "c", "d", "e"]} ) # Doesn't work as expected print("Shuffle dataset") for _ in range(3): print(data.shuffle(seed=None)[:]) # This seems to work with pandas print("\nShuffle via pandas") for _ in range(3): df = data.to_pandas().sample(frac=1.0) print(datasets.Dataset.from_pandas(df, preserve_index=False)[:]) ``` ## Expected results I assumed that the default setting would initialize a new/random state of a `np.random.BitGenerator` (see [docs](https://huggingface.co/docs/datasets/package_reference/main_classes.html?highlight=shuffle#datasets.Dataset.shuffle)). Wouldn't that reshuffle the rows each time I call `data.shuffle()`? ## Actual results ```bash Shuffle dataset {'feature': [5, 1, 3, 2, 4], 'label': ['e', 'a', 'c', 'b', 'd']} {'feature': [5, 1, 3, 2, 4], 'label': ['e', 'a', 'c', 'b', 'd']} {'feature': [5, 1, 3, 2, 4], 'label': ['e', 'a', 'c', 'b', 'd']} Shuffle via pandas {'feature': [4, 2, 3, 1, 5], 'label': ['d', 'b', 'c', 'a', 'e']} {'feature': [2, 5, 3, 4, 1], 'label': ['b', 'e', 'c', 'd', 'a']} {'feature': [5, 2, 3, 1, 4], 'label': ['e', 'b', 'c', 'a', 'd']} ``` ## Environment info <!-- You can run the command `datasets-cli env` and copy-and-paste its output below. --> - `datasets` version: 1.18.0 - Platform: Linux-5.13.0-27-generic-x86_64-with-glibc2.17 - Python version: 3.8.12 - PyArrow version: 6.0.1

Adding CC-100: Monolingual Datasets from Web Crawl Data (Datasets links are invalid)

open

CONTRIBUTOR

## Describe the bug The dataset links are no longer valid for CC-100. It seems that the website which was keeping these files are no longer accessible and therefore this dataset became unusable. Check out the dataset [homepage](http://data.statmt.org/cc-100/) which isn't accessible. Also the URLs for dataset file per language isn't accessible: http://data.statmt.org/cc-100/<language code here>.txt.xz (language codes: am, sr, ka, etc.) ## Steps to reproduce the bug ```python from datasets import load_dataset dataset = load_dataset("cc100", "ka") ``` It throws 503 error. ## Expected results It should successfully download and load dataset but it throws an exception because the dataset files are no longer accessible. ## Environment info Run from google colab. Just installed the library using pip: ```!pip install -U datasets```

Dataset Card Creator drops information for "Additional Information" Section

open

NONE

First of all, the card creator is a great addition and really helpful for streamlining dataset cards! ## Describe the bug I encountered an inconvenient bug when entering "Additional Information" in the react app, which drops already entered text when switching to a previous section, and then back again to "Additional Information". I was able to reproduce the issue in both Firefox and Chrome, so I suspect a problem with the React logic that doesn't expect users to switch back in the final section. Edit: I'm also not sure whether this is the right place to open the bug report on, since it's not clear to me which particular project it belongs to, or where I could find associated source code. ## Steps to reproduce the bug 1. Navigate to the Section "Additional Information" in the [dataset card creator](https://huggingface.co/datasets/card-creator/) 2. Enter text in an arbitrary field, e.g., "Dataset Curators". 3. Switch back to a previous section, like "Dataset Creation". 4. When switching back again to "Additional Information", the text has been deleted. Notably, this behavior can be reproduced again and again, it's not just problematic for the first "switch-back" from Additional Information. ## Expected results For step 4, the previously entered information should still be present in the boxes, similar to the behavior to all other sections (switching back there works as expected) ## Actual results The text boxes are empty again, and previously entered text got deleted. ## Environment info - `datasets` version: N/A - Platform: Firefox 96.0 / Chrome 97.0 - Python version: N/A - PyArrow version: N/A

Add a metadata field for when source data was produced

open

CONTRIBUTOR

**Is your feature request related to a problem? Please describe.** The current problem is that information about when source data was produced is not easily visible. Though there are a variety of metadata fields available in the dataset viewer, time period information is not included. This feature request suggests making metadata relating to the time that the underlying *source* data was produced more prominent and outlines why this specific information is of particular importance, both in domain-specific historic research and more broadly. **Describe the solution you'd like** There are a variety of metadata fields exposed in the dataset viewer (license, task categories, etc.) These fields make this metadata more prominent both for human users and as potentially machine-actionable information (for example, through the API). I would propose to add a metadata field that says when some underlying data was produced. For example, a dataset would be labelled as being produced between `1800-1900`. **Describe alternatives you've considered** This information is sometimes available in the Datacard or a paper describing the dataset. However, it's often not that easy to identify or extract this information, particularly if you want to use this field as a filter to identify relevant datasets. **Additional context** I believe this feature is relevant for a number of reasons: - Increasingly, there is an interest in using historical data for training language models (for example, https://huggingface.co/dbmdz/bert-base-historic-dutch-cased), and datasets to support this task (for example, https://huggingface.co/datasets/bnl_newspapers). For these datasets, indicating the time periods covered is particularly relevant. - More broadly, time is likely a common source of domain drift. Datasets of movie reviews from the 90s may not work well for recent movie reviews. As the documentation and long-term management of ML data become more of a priority, quickly understanding the time when the underlying text (or other data types) is arguably more important. - time-series data: datasets are adding more support for time series data. Again, the periods covered might be particularly relevant here. **open questions** - I think some of my points above apply not only to the underlying data but also to annotations. As a result, there could also be an argument for encoding this information somewhere. However, I would argue (but could be persuaded otherwise) that this is probably less important for filtering. This type of context is already addressed in the datasheets template and often requires more narrative to discuss. - what level of granularity would make sense for this? e.g. assigning a decade, century or year? - how to encode this information? What formatting makes sense - what specific time to encode; a data range? (mean, modal, min, max value?) This is a slightly amorphous feature request - I would be happy to discuss further/try and propose a more concrete solution if this seems like something that could be worth considering. I realise this might also touch on other parts of the 🤗 hubs ecosystem.

TIMIT Dataset not working with GPU

open

NONE

## 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}.")

I've refactored the code in order to make the dataset streamable and to avoid it takes too long: - I've used `iter_files` Close #3615

Add support for continuous metrics (RMSE, MAE)

open

NONE

**Is your feature request related to a problem? Please describe.** I am uploading our dataset and models for the "Constructing interval measures" method we've developed, which uses item response theory to convert multiple discrete labels into a continuous spectrum for hate speech. Once we have this outcome our NLP models conduct regression rather than classification, so binary metrics are not relevant. The only continuous metrics available at https://huggingface.co/metrics are pearson & spearman correlation, which don't ensure that the prediction is on the same scale as the outcome. **Describe the solution you'd like** I would like to be able to tag our models on the Hub with the following metrics: - RMSE - MAE **Describe alternatives you've considered** I don't know if there are any alternatives. **Additional context** Our preprint is available here: https://arxiv.org/abs/2009.10277 . We are making it available for use in Jigsaw's Toxic Severity Rating Kaggle competition: https://www.kaggle.com/c/jigsaw-toxic-severity-rating/overview . I have our first model uploaded to the Hub at https://huggingface.co/ucberkeley-dlab/hate-measure-roberta-large Thanks, Chris
