[ "> It looks like the CI is failing on windows because our windows CI is unable to clone the bigbench repository (maybe it has to do with filenames that are longer than 256 characters, which windows don't like).

If it's an issue with windows not liking long filenames after it's installed, then it will not be resolved.\r\nI don't have a windows computer to try it on, but I might be able to tweek this PR and do an experiment to find out. \r\nWe're waiting for a quota increase for the pip install (https://github.com/pypa/pypi-support/issues/1782). It's been pending for 2-3 weeks, and I don't have an estimate for when it will be resolved. \r\n\r\n>Regarding the dummy data zip files, I think we can just keep datasets/bigbench/dummy/abstract_narrative_understanding/1.0.0/dummy_data.zip and remove all the other ones.

[ "Hi! Replacing:\r\n```python\r\ntransformed_dataset = dataset.with_transform(transforms)\r\ntransformed_dataset.set_format(type=\"torch\", device=\"cuda\")\r\n```\r\n\r\nwith:\r\n```python\r\ndef transform_func(examples):\r\n examples[\"image\"] = [transforms(img).to(\"cuda\") for img in examples[\"image\"]]\r\n return examples\r\n\r\ntransformed_dataset = dataset.with_transform(transform_func)\r\n```\r\nshould fix the issue. `datasets` doesn't support chaining of transforms (you can think of `set_format`/`with_format` as a predefined transform func for `set_transform`/`with_transforms`), so the last transform (in your case, `set_format`) takes precedence over the previous ones (in your case `with_format`). And the PyTorch formatter is not supported by the Image feature, hence the error (adding support for that is on our short-term roadmap).", "Ok thanks a lot for the code snippet!\r\n\r\nI love the way `datasets` is easy to use but it made it really long to pre-process all the images (400.000 in my case) before training anything. `ImageFolder` from pytorch is faster in my case but force me to have the images on my local machine.\r\n\r\nI don't know how to speed up the process without switching to `ImageFolder` :smile: ", "You can pass `ignore_verifications=True` in `load_dataset` to skip checksum verification, which takes a lot of time if the number of files is large.

[ "Hi ! Indeed there was a breaking change in `huggingface_hub` 0.5.0 in `HfApi.create_repo`, which is called here in `datasets` by passing the org name in both the `repo_id` and the `organization` arguments:\r\n\r\nhttps://github.com/huggingface/datasets/blob/2230f7f7d7fbaf102cff356f5a8f3bd1561bea43/src/datasets/arrow_dataset.py#L3363-L3369\r\n\r\nI think we should fix that in `huggingface_hub`, will keep you posted. In the meantime please use `huggingface_hub` 0.4.0", "I'll be sending a fix for this later today on the `huggingface_hub` side.\r\n\r\nThe error would be converted to a `FutureWarning` if `datasets` uses kwargs instead of positional, for example here: \r\n\r\nhttps://github.com/huggingface/datasets/blob/2230f7f7d7fbaf102cff356f5a8f3bd1561bea43/src/datasets/arrow_dataset.py#L3363-L3369\r\n\r\nto be:\r\n\r\n``` python\r\n api.create_repo(\r\n name=dataset_name,\r\n token=token,\r\n repo_type=\"dataset\",\r\n organization=organization,\r\n private=private,\r\n )\r\n```\r\n\r\nBut `name` and `organization` are deprecated in `huggingface_hub=0.5`, and people should pass `repo_id='org/name` instead. Note that `repo_id` was introduced in 0.5 and if `datasets` wants to support older `huggingface_hub` versions (which I encourage it to do), there needs to be a helper function to do that. It can be something like:\r\n\r\n\r\n```python\r\ndef create_repo(\r\n client,\r\n name: str,\r\n token: Optional[str] = None,\r\n organization: Optional[str] = None,\r\n private: Optional[bool] = None,\r\n repo_type: Optional[str] = None,\r\n exist_ok: Optional[bool] = False,\r\n space_sdk: Optional[str] = None,\r\n) -> str:\r\n try:\r\n return client.create_repo(\r\n repo_id=f\"{organization}/{name}\",\r\n token=token,\r\n private=private,\r\n repo_type=repo_type,\r\n exist_ok=exist_ok,\r\n space_sdk=space_sdk,\r\n )\r\n except TypeError:\r\n return client.create_repo(\r\n name=name,\r\n organization=organization,\r\n token=token,\r\n private=private,\r\n repo_type=repo_type,\r\n exist_ok=exist_ok,\r\n space_sdk=space_sdk,\r\n )\r\n```\r\n\r\nin a `utils/_fixes.py` kinda file and and be used internally.\r\n\r\nI'll be sending a patch to `huggingface_hub` to convert the error reported in this issue to a `FutureWarning`.", "PR with the hotfix on the `huggingface_hub` side: https://github.com/huggingface/huggingface_hub/pull/822", "We can definitely change `push_to_hub` to use `repo_id` in `datasets` and require `huggingface_hub>=0.5.0`.\r\n\r\nLet me open a PR :)", "`huggingface_hub` 0.5.1 just got released with a fix, feel free to update `huggingface_hub` ;)" ]

[ "Hi @andreybond, thanks for reporting.\r\n\r\nUnfortunately, I'm not able to able to reproduce your issue:\r\n```python\r\nIn [4]: from datasets import load_dataset\r\n ...: datasets = load_dataset(\"nielsr/XFUN\", \"xfun.ja\")\r\n\r\nIn [5]: datasets\r\nOut[5]: \r\nDatasetDict({\r\n train: Dataset({\r\n features: ['id', 'input_ids', 'bbox', 'labels', 'image', 'entities', 'relations'],\r\n num_rows: 194\r\n })\r\n validation: Dataset({\r\n features: ['id', 'input_ids', 'bbox', 'labels', 'image', 'entities', 'relations'],\r\n num_rows: 71\r\n })\r\n})\r\n```\r\n\r\nThe only reason I can imagine this issue may arise is if your default encoding is not \"UTF-8\" (and it is ASCII instead). This is usually the case on Windows machines; but you say your environment is a Linux machine. Maybe you change your machine default encoding?\r\n\r\nCould you please check this?\r\n```python\r\nIn [6]: import sys\r\n\r\nIn [7]: sys.getdefaultencoding()\r\nOut[7]: 'utf-8'\r\n```", "I opened a PR in the original dataset loading script:\r\n- microsoft/unilm#677\r\n\r\nand fixed the corresponding dataset script on the Hub:\r\n- https://huggingface.co/datasets/nielsr/XFUN/commit/73ba5e026621e05fb756ae0f267eb49971f70ebd", "import sys\r\nsys.getdefaultencoding()\r\n\r\nreturned: 'utf-8'\r\n\r\n---------------------\r\n\r\nI've just cloned master branch - your fix works! Thank you!" ]

[ "Hi @jacobbieker, thanks for your request and study of possible alternatives.\r\n\r\nWe are very interested in finding a way to make `datasets` useful to you.\r\n\r\nLooking at the Zarr docs, I saw that among its storage alternatives, there is the ZIP file format: https://zarr.readthedocs.io/en/stable/api/storage.html#zarr.storage.ZipStore\r\n\r\nThis might be convenient for many reasons:\r\n- On the one hand, we avoid the Git issue with huge number of small files: chunks files are compressed into a single ZIP file\r\n- On the other hand, the ZIP file format is specially suited for streaming data because it allows random access to its component files (i.e. it supports random access to its chunks)\r\n\r\nAnyway, I think that a Python loading script will be necessary: you need to implement additional logic to select certain chunks (based on date or other criteria).\r\n\r\nPlease, let me know if this makes sense to you.", "Ah okay, I missed the option of zip files for zarr, I'll try that with our repos and see if it works! Thanks a lot!", "Hi @jacobbieker, does the Zarr ZipStore work for your use case?", "Hi,\r\n\r\nYes, it seems to!

[ "Hi! Yes, the problem with `add_item` is that it keeps examples in memory, so you are left with these options:\r\n* writing a dataset loading script in which you iterate over `custom_example_dict_streamer` and yield the examples (in `_generate examples`)\r\n* storing the data in a JSON/CSV/Parquet/TXT file and using `Dataset.from_{format}`\r\n* using `add_item` + `save_to_disk` on smaller chunks: \r\n ```python\r\n from datasets import Dataset, concatenate_datasets\r\n MAX_SAMPLES_IN_MEMORY = 1000\r\n samples_in_dset = 0\r\n dset = Dataset.from_dict({\"col1\": [], \"col2\": []}) # empty dataset\r\n path_to_save_dir = \"path/to/save/dir\"\r\n num_chunks = 0\r\n for example_dict in custom_example_dict_streamer(\"/path/to/raw/data\"):\r\n dset = dset.add_item(example_dict)\r\n samples_in_dset += 1\r\n if samples_in_dset == MAX_SAMPLES_IN_MEMORY:\r\n samples_in_dset = 0\r\n dset.save_to_disk(f\"{path_to_save_dir}{num_chunks}\")\r\n num_chunks =+ 1\r\n dset = Dataset.from_dict({\"col1\": [], \"col2\": []}) # empty dataset\r\n if samples_in_dset > 0:\r\n dset.save_to_disk(f\"{path_to_save_dir}{num_chunks}\")\r\n num_chunks =+ 1\r\n loaded_dsets = [] # memory-mapped\r\n for chunk_num in range(num_chunks):\r\n dset = Dataset.load_from_disk(f\"{path_to_save_dir}{chunk_num}\") \r\n loaded_dsets.append(dset)\r\n final_dset = concatenate_datasets(dset)\r\n ```\r\n If you still have issues with this approach, you can try to delete unused datasets with `gc.collect()` to free some memory.
