### Describe the bug When I use load_dataset to load the nyanko7/danbooru2023 data set, the cache is read in the form of a symlink. There may be a problem with the arrow_dataset initialization process and I get FileNotFoundError: [Errno 2] No such file or directory: '2945000.jpg' ### Steps to reproduce the bug #code show as below from datasets import load_dataset data = load_dataset("nyanko7/danbooru2023",cache_dir=<symlink>) data["train"][0] ### Expected behavior I should get this result: {'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=365x256 at 0x7FB730CB4070>, 'label': 0} ### Environment info datasets==2.12.0 python==3.10.14

### Describe the bug I have a multilingual dataset that contains a lot of subsets. Each subset corresponds to a pair of languages, you can see here an example with 250 subsets: [https://hf.co/datasets/loicmagne/open-subtitles-250-bitext-mining](). As part of the MTEB benchmark, we may need to load all the subsets of the dataset. The dataset is relatively small and contains only ~45MB of data, but when I try to load every subset, it takes 15 minutes from the HF hub and 13 minutes from the cache This issue https://github.com/huggingface/datasets/issues/5499 also referenced this overhead, but I'm wondering if there is anything I can do to speedup loading different subsets of the same dataset, both when loading from disk and from the HF hub? Currently each subset is stored in a jsonl file ### Steps to reproduce the bug ``` from datasets import load_dataset for subset in ['ka-ml', 'br-sr', 'bg-br', 'kk-lv', 'br-sk', 'br-fi', 'eu-ze_zh', 'kk-nl', 'kk-vi', 'ja-kk', 'br-sv', 'kk-zh_cn', 'kk-ms', 'br-et', 'br-hu', 'eo-kk', 'br-tr', 'ko-tl', 'te-zh_tw', 'br-hr', 'br-nl', 'ka-si', 'br-cs', 'br-is', 'br-ro', 'br-de', 'et-kk', 'fr-hy', 'br-no', 'is-ko', 'br-da', 'br-en', 'eo-lt', 'is-ze_zh', 'eu-ko', 'br-it', 'br-id', 'eu-zh_cn', 'is-ja', 'br-sl', 'br-gl', 'br-pt_br', 'br-es', 'br-pt', 'is-th', 'fa-is', 'br-ca', 'eu-ka', 'is-zh_cn', 'eu-ur', 'id-kk', 'br-sq', 'eu-ja', 'uk-ur', 'is-zh_tw', 'ka-ko', 'eu-zh_tw', 'eu-th', 'eu-is', 'is-tl', 'br-eo', 'eo-ze_zh', 'eu-te', 'ar-kk', 'eo-lv', 'ko-ze_zh', 'ml-ze_zh', 'is-lt', 'br-fr', 'ko-te', 'kk-sl', 'eu-fa', 'eo-ko', 'ka-ze_en', 'eo-eu', 'ta-zh_tw', 'eu-lv', 'ko-lv', 'lt-tl', 'eu-si', 'hy-ru', 'ar-is', 'eu-lt', 'eu-tl', 'eu-uk', 'ka-ze_zh', 'si-ze_zh', 'el-is', 'bn-is', 'ko-ze_en', 'eo-si', 'cs-kk', 'is-uk', 'eu-ze_en', 'ta-ze_zh', 'is-pl', 'is-mk', 'eu-ta', 'ko-lt', 'is-lv', 'fa-ko', 'bn-ko', 'hi-is', 'bn-ze_zh', 'bn-eu', 'bn-ja', 'is-ml', 'eu-ru', 'ko-ta', 'is-vi', 'ja-tl', 'eu-mk', 'eu-he', 'ka-zh_tw', 'ka-zh_cn', 'si-tl', 'is-kk', 'eu-fi', 'fi-ko', 'is-ur', 'ka-th', 'ko-ur', 'eo-ja', 'he-is', 'is-tr', 'ka-ur', 'et-ko', 'eu-vi', 'is-sk', 'gl-is', 'fr-is', 'is-sq', 'hu-is', 'fr-kk', 'eu-sq', 'is-ru', 'ja-ka', 'fi-tl', 'ka-lv', 'fi-is', 'is-si', 'ar-ko', 'ko-sl', 'ar-eu', 'ko-si', 'bg-is', 'eu-hu', 'ko-sv', 'bn-hu', 'kk-ro', 'eu-hi', 'ka-ms', 'ko-th', 'ko-sr', 'ko-mk', 'fi-kk', 'ka-vi', 'eu-ml', 'ko-ml', 'de-ko', 'fa-ze_zh', 'eu-sk', 'is-sl', 'et-is', 'eo-is', 'is-sr', 'is-ze_en', 'kk-pt_br', 'hr-hy', 'kk-pl', 'ja-ta', 'is-ms', 'hi-ze_en', 'is-ro', 'ko-zh_cn', 'el-eu', 'ka-pl', 'ka-sq', 'eu-sl', 'fa-ka', 'ko-no', 'si-ze_en', 'ko-uk', 'ja-ze_zh', 'hu-ko', 'kk-no', 'eu-pl', 'is-pt_br', 'bn-lv', 'tl-zh_cn', 'is-nl', 'he-ko', 'ko-sq', 'ta-th', 'lt-ta', 'da-ko', 'ca-is', 'is-ta', 'bn-fi', 'ja-ml', 'lv-si', 'eu-sv', 'ja-te', 'bn-ur', 'bn-ca', 'bs-ko', 'bs-is', 'eu-sr', 'ko-vi', 'ko-zh_tw', 'et-tl', 'kk-tr', 'eo-vi', 'is-it', 'ja-ko', 'eo-et', 'id-is', 'bn-et', 'bs-eu', 'bn-lt', 'tl-uk', 'bn-zh_tw', 'da-eu', 'el-ko', 'no-tl', 'ko-sk', 'is-pt', 'hu-kk', 'si-zh_tw', 'si-te', 'ka-ru', 'lt-ml', 'af-ja', 'bg-eu', 'eo-th', 'cs-is', 'pl-ze_zh', 'el-kk', 'kk-sv', 'ka-nl', 'ko-pl', 'bg-ko', 'ka-pt_br', 'et-eu', 'tl-zh_tw', 'ka-pt', 'id-ko', 'fi-ze_zh', 'he-kk', 'ka-tr']: load_dataset('loicmagne/open-subtitles-250-bitext-mining', subset) ``` ### Expected behavior Faster loading? ### Environment info Copy-and-paste the text below in your GitHub issue. - `datasets` version: 2.18.0 - Platform: Linux-6.5.0-27-generic-x86_64-with-glibc2.35 - Python version: 3.10.12 - `huggingface_hub` version: 0.22.2 - PyArrow version: 15.0.2 - Pandas version: 2.2.2 - `fsspec` version: 2023.5.0

### Describe the bug The [`DatasetBuilder._split_generators`](https://github.com/huggingface/datasets/blob/0f27d7b77c73412cfc50b24354bfd7a3e838202f/src/datasets/builder.py#L1449) function has currently the following signature: ```python class DatasetBuilder: def _split_generators(self, dl_manager: DownloadManager): ... ``` However, the `dl_manager` argument can also be of type [`StreamingDownloadManager`](https://github.com/huggingface/datasets/blob/0f27d7b77c73412cfc50b24354bfd7a3e838202f/src/datasets/download/streaming_download_manager.py#L962), which has different functionality. For example, the `download` function doesn't download, but rather just returns the given url(s). I suggest changing the function signature to: ```python class DatasetBuilder: def _split_generators(self, dl_manager: Union[DownloadManager, StreamingDownloadManager]): ... ``` and also adjust the docstring accordingly. I would like to create a Pull Request to fix this, and have the following questions: * Are there also other options than `DownloadManager`, and `StreamingDownloadManager`? * Should this also be changed in other functions? ### Steps to reproduce the bug Minimal example to print the different class names: ```python import tempfile from datasets import load_dataset example = b''' from datasets import GeneratorBasedBuilder, DatasetInfo, Features, Value, SplitGenerator class Test(GeneratorBasedBuilder): def _info(self): return DatasetInfo(features=Features({"x": Value("int64")})) def _split_generators(self, dl_manager): print(type(dl_manager)) return [SplitGenerator('test')] def _generate_examples(self): yield 0, {'x': 42} ''' with tempfile.NamedTemporaryFile(suffix='.py') as f: f.write(example) f.flush() load_dataset(f.name, streaming=False) load_dataset(f.name, streaming=True) ``` ### Expected behavior complete type annotations ### Environment info /

...for faster dataset download when there are many many small files (e.g. imagefolder, audiofolder) ### Behcnmark for example on [lhoestq/tmp-images-writer_batch_size](https://hf.co/datasets/lhoestq/tmp-images-writer_batch_size) (128 images) | | duration of the download step in `load_dataset()` | |--| ----------------------------------------------------------------------| | Before | 58s | | Now | 3s | This should fix issues with the Dataset Viewer taking too much time to show up for imagefolder/audiofolder datasets. ### Implementation details The main change is in the `DownloadManager`: ```diff - download_func = partial(self._download, download_config=download_config) + download_func = partial(self._download_batched, download_config=download_config) downloaded_path_or_paths = map_nested( download_func, url_or_urls, map_tuple=True, num_proc=download_config.num_proc, desc="Downloading data files", + batched=True, + batch_size=-1, ) ``` and `_download_batched` is a multithreaded function. I only enable multithreading if there are more than 16 files and files are small though, otherwise the progress bar that counts the number of downloaded files is not fluid (updating when a big batch of big files are done downloading). To do so I simply check if the first file is smaller than 20MB. I also had to tweak `map_nested` to support batching. In particular it slices the data correctly if the user also enables multiprocessing.

### Describe the bug I'd expect the following code to download just the validation split but instead I get all data on my disk (train, test and validation splits) ` from datasets import load_dataset dataset = load_dataset("imagenet-1k", split="validation", trust_remote_code=True) ` Is it expected to work like that? ### Steps to reproduce the bug 1. Install the required libraries (python, datasets, huggingface_hub) 2. Login using huggingface cli 2. Run the code in the description ### Expected behavior Just a single (validation) split should be downloaded. ### Environment info python: 3.12.2 datasets: 2.18.0 huggingface_hub: 0.22.2

When `n` vectors are (...) 224 `dtype` must be float32. 225 """ --> 227 n, d = x.shape 228 assert d == self.d 229 x = np.ascontiguousarray(x, dtype='float32') ValueError: not enough values to unpack (expected 2, got 1) ``` ### Steps to reproduce the bug 1. Load any dataset like `ds = datasets.load_dataset("wikimedia/wikipedia", "20231101.en")["train"]` 2. Add an FAISS index on any column `ds.add_faiss_index('title')` ### Expected behavior The index should be created ### Environment info - `datasets` version: 2.18.0 - Platform: Linux-6.5.0-26-generic-x86_64-with-glibc2.35 - Python version: 3.9.19 - `huggingface_hub` version: 0.22.2 - PyArrow version: 15.0.2 - Pandas version: 2.2.1 - `fsspec` version: 2024.2.0 - `faiss-cpu` version: 1.8.0

### Describe the bug Hello, I've been struggling with a problem using Huggingface datasets caused by PyArrow memory allocation. I finally managed to solve it, and thought to document it since similar issues have been raised here before (https://github.com/huggingface/datasets/issues/5710, https://github.com/huggingface/datasets/issues/6176). In my case, I was trying to load ~70k dataset files from disk using `datasets.load_from_disk(data_path)` (meaning 70k repeated calls to load_from_disk). This triggered an (uninformative) exception around 64k loaded files: ``` File "pyarrow/io.pxi", line 1053, in pyarrow.lib.memory_map File "pyarrow/io.pxi", line 1000, in pyarrow.lib.MemoryMappedFile._open File "pyarrow/error.pxi", line 154, in pyarrow.lib.pyarrow_internal_check_status File "pyarrow/error.pxi", line 91, in pyarrow.lib.check_status OSError: Memory mapping file failed: Cannot allocate memory ``` Despite system RAM usage being very low. After a lot of digging around, I discovered that my Ubuntu machine had a limit on the maximum number of memory mapped files in `/proc/sys/vm/max_map_count` set to 65530, which was causing my data loader to crash. Increasing the limit in the file (`echo <new_mmap_size> | sudo tee /proc/sys/vm/max_map_count`) made the issue go away. While this isn't a bug as such in either Datasets or PyArrow, this behavior can be very confusing to users. Maybe this should be mentioned in documentation? I suspect the other issues raised here about memory mapping OOM errors could actually be consequence of system configuration. Br, Lauri ### Steps to reproduce the bug ``` import numpy as np import pyarrow as pa import tqdm # Write some data to disk arr = pa.array(np.arange(100)) schema = pa.schema([ pa.field('nums', arr.type) ]) with pa.OSFile('arraydata.arrow', 'wb') as sink: with pa.ipc.new_file(sink, schema=schema) as writer: batch = pa.record_batch([arr], schema=schema) writer.write(batch) # Number of times to open the memory map nums = 70000 # Read the data back arrays = [pa.memory_map('arraydata.arrow', 'r') for _ in tqdm.tqdm(range(nums))] ``` ### Expected behavior No errors. ### Environment info datasets: 2.18.0 pyarrow: 15.0.0

### Describe the bug Map has been taking extremely long to preprocess my data. It seems to process 1000 examples (which it does really fast in about 10 seconds), then it hangs for a good 1-2 minutes, before it moves on to the next batch of 1000 examples. It also keeps eating up my hard drive space for some reason by creating a file named tmp1335llua that is over 300GB. Trying to set num_proc to be >1 also gives me the following error: NameError: name 'processor' is not defined Please advise on how I could optimise this? ### Steps to reproduce the bug In general, I have been using map as per normal. Here is a snippet of my code: ```` ########################### DATASET LOADING AND PREP ######################### def load_custom_dataset(split): ds = [] if split == 'train': for dset in args.train_datasets: ds.append(load_from_disk(dset)) if split == 'test': for dset in args.test_datasets: ds.append(load_from_disk(dset)) ds_to_return = concatenate_datasets(ds) ds_to_return = ds_to_return.shuffle(seed=22) return ds_to_return def prepare_dataset(batch): # load and (possibly) resample audio data to 16kHz audio = batch["audio"] # compute log-Mel input features from input audio array batch["input_features"] = processor.feature_extractor(audio["array"], sampling_rate=audio["sampling_rate"]).input_features[0] # compute input length of audio sample in seconds batch["input_length"] = len(audio["array"]) / audio["sampling_rate"] # optional pre-processing steps transcription = batch["sentence"] if do_lower_case: transcription = transcription.lower() if do_remove_punctuation: transcription = normalizer(transcription).strip() # encode target text to label ids batch["labels"] = processor.tokenizer(transcription).input_ids return batch print('DATASET PREPARATION IN PROGRESS...') # case 3: combine_and_shuffle is true, only train provided # load train datasets train_set = load_custom_dataset('train') # split dataset raw_dataset = DatasetDict() raw_dataset = train_set.train_test_split(test_size = args.test_size, shuffle=True, seed=42) raw_dataset = raw_dataset.cast_column("audio", Audio(sampling_rate=args.sampling_rate)) print("Before Map:") print(raw_dataset) raw_dataset = raw_dataset.map(prepare_dataset, num_proc=1) print("After Map:") print(raw_dataset) ```` ### Expected behavior Based on the speed at which map is processing examples, I would expect a 5-6 hours completion for all mapping However, because it hangs every 1000 examples, I instead roughly estimate it would take about 40 hours! Moreover, i cant even finish the map because it keeps exponentially eating up my hard drive space ### Environment info - `datasets` version: 2.18.0 - Platform: Windows-10-10.0.22631-SP0 - Python version: 3.10.14 - `huggingface_hub` version: 0.22.2 - PyArrow version: 15.0.2 - Pandas version: 2.2.1 - `fsspec` version: 2024.2.0

### Describe the bug Hello, I have a question regarding the map function in the Hugging Face datasets. The situation is as follows: when I load a jsonl file using load_dataset(..., streaming=False), and then utilize the map function to process it, I specify that the returned example should be of type Torch.tensor. However, I noticed that after applying the map function, the datatype automatically changes to List, which leads to errors in my program. I attempted to use load_dataset(..., streaming=True), and this issue no longer occurs. I'm not entirely clear on why this happens. Could you please provide some insights into this? ### Steps to reproduce the bug 1.dataset = load_dataset(xxx, streaming = False) 2. dataset.map(function), function will return torch.Tensor. 3. you will find the format of data in dataset is List. ### Expected behavior I expected to receieve the format of data is torch.Tensor. ### Environment info 2.18.0

### Describe the bug ```python from datasets import Dataset def worker(example): while True: continue example['a'] = 100 return example data = Dataset.from_list([{"a": 1}, {"a": 2}]) data = data.map(worker) print(data[0]) ``` I'm implementing a worker function whose runtime will depend on specific examples (e.g., while most examples take 0.01s in worker, several examples may take 50s). Therefore, I would like to know how the current implementation will handle those subprocesses that require a long (e.g., >= 5min) or even infinite time. I notice that the current implementation set a timeout of 0.05 second https://github.com/huggingface/datasets/blob/c3ddb1ef00334a6f973679a51e783905fbc9ef0b/src/datasets/utils/py_utils.py#L674 However, this example code still gets stuck. ### Steps to reproduce the bug run the example above ### Expected behavior I want to set a default worker to handle these timeout cases, instead of getting stuck ### Environment info main branch version

PR for issue #6782. Makes `cast_storage` of the `Image` class faster by removing the slow call to `.pylist`. Instead directly convert each `ListArray` item to either `Array2DExtensionType` or `Array3DExtensionType`. This also preserves the `dtype` removing the warning if the array is already `uint8`.

Also note that the docs page is still https://huggingface.co/docs/datasets-server/, so I didn't change it.

Instead of waiting for data files to be extracted in the packaged builders, we can prepend the compression prefix and extract them as they are being read (using `fsspec`). This saves disk space (deleting extracted archives is not set by default) and slightly speeds up dataset generation (less disk reads)

Update: see comments below ### Describe the bug Operations that save an image from a path are very slow. I believe the reason for this is that the image data (`numpy`) is converted into `pyarrow` format but then back to python using `.pylist()` before being converted to a numpy array again. `pylist` is already slow but used on a multi-dimensional numpy array such as an image it takes a very long time. From the trace below we can see that `__arrow_array__` takes a long time. It is currently also called in `get_inferred_type`, this should be removable #6781 but doesn't change the underyling issue. The conversion to `pyarrow` and back also leads to the `numpy` array having type `int64` which causes a warning message because the image type excepts `uint8`. However, originally the `numpy` image array was in `uint8`. ### Steps to reproduce the bug ```python from PIL import Image import numpy as np import datasets import cProfile image = Image.fromarray(np.random.randint(0, 255, (2048, 2048, 3), dtype=np.uint8)) image.save("test_image.jpg") ds = datasets.Dataset.from_dict( {"image": ["test_image.jpg"]}, features=datasets.Features({"image": datasets.Image(decode=True)}), ) # load as numpy array, e.g. for further processing with map # same result as map returning numpy arrays ds.set_format("numpy") cProfile.run("ds.map(writer_batch_size=1, load_from_cache_file=False)", "restats") ``` ```bash Fri Apr 5 14:56:17 2024 restats 66817 function calls (64992 primitive calls) in 33.382 seconds Ordered by: cumulative time List reduced from 1073 to 20 due to restriction <20> ncalls tottime percall cumtime percall filename:lineno(function) 46/1 0.000 0.000 33.382 33.382 {built-in method builtins.exec} 1 0.000 0.000 33.382 33.382 <string>:1(<module>) 1 0.000 0.000 33.382 33.382 arrow_dataset.py:594(wrapper) 1 0.000 0.000 33.382 33.382 arrow_dataset.py:551(wrapper) 1 0.000 0.000 33.379 33.379 arrow_dataset.py:2916(map) 4 0.000 0.000 33.327 8.332 arrow_dataset.py:3277(_map_single) 1 0.000 0.000 33.311 33.311 arrow_writer.py:465(write) 2 0.000 0.000 33.311 16.656 arrow_writer.py:423(write_examples_on_file) 1 0.000 0.000 33.311 33.311 arrow_writer.py:527(write_batch) 2 14.484 7.242 33.260 16.630 arrow_writer.py:161(__arrow_array__) 1 0.001 0.001 16.438 16.438 arrow_writer.py:121(get_inferred_type) 1 0.000 0.000 14.398 14.398 threading.py:637(wait) 1 0.000 0.000 14.398 14.398 threading.py:323(wait) 8 14.398 1.800 14.398 1.800 {method 'acquire' of '_thread.lock' objects} 4/2 0.000 0.000 4.337 2.169 table.py:1800(wrapper) 2 0.000 0.000 4.337 2.169 table.py:1950(cast_array_to_feature) 2 0.475 0.238 4.337 2.169 image.py:209(cast_storage) 9 2.583 0.287 2.583 0.287 {built-in method numpy.array} 2 0.000 0.000 1.284 0.642 image.py:319(encode_np_array) 2 0.000 0.000 1.246 0.623 image.py:301(image_to_bytes) ``` ### Expected behavior The `numpy` image data should be passed through as it will be directly consumed by `pillow` to convert it to bytes. As an example one can replace `list_of_np_array_to_pyarrow_listarray(data)` in `__arrow_array__` with just `out = data` as a test. We have to change `cast_storage` of the `Image` feature so it handles the passed through data (& if to handle type before) ```python bytes_array = pa.array( [encode_np_array(arr)["bytes"] if arr is not None else None for arr in storage], type=pa.binary(), ) ``` Leading to the following: ```bash Fri Apr 5 15:44:27 2024 restats 66419 function calls (64595 primitive calls) in 0.937 seconds Ordered by: cumulative time List reduced from 1023 to 20 due to restriction <20> ncalls tottime percall cumtime percall filename:lineno(function) 47/1 0.000 0.000 0.935 0.935 {built-in method builtins.exec} 2/1 0.000 0.000 0.935 0.935 <string>:1(<module>) 2/1 0.000 0.000 0.934 0.934 arrow_dataset.py:594(wrapper) 2/1 0.000 0.000 0.934 0.934 arrow_dataset.py:551(wrapper) 2/1 0.000 0.000 0.934 0.934 arrow_dataset.py:2916(map) 4 0.000 0.000 0.933 0.233 arrow_dataset.py:3277(_map_single) 1 0.000 0.000 0.883 0.883 arrow_writer.py:466(write) 2 0.000 0.000 0.883 0.441 arrow_writer.py:424(write_examples_on_file) 1 0.000 0.000 0.882 0.882 arrow_writer.py:528(write_batch) 2 0.000 0.000 0.877 0.439 arrow_writer.py:161(__arrow_array__) 4/2 0.000 0.000 0.877 0.439 table.py:1800(wrapper) 2 0.000 0.000 0.877 0.439 table.py:1950(cast_array_to_feature) 2 0.009 0.005 0.877 0.439 image.py:209(cast_storage) 2 0.000 0.000 0.868 0.434 image.py:335(encode_np_array) 2 0.000 0.000 0.856 0.428 image.py:317(image_to_bytes) 2 0.000 0.000 0.822 0.411 Image.py:2376(save) 2 0.000 0.000 0.822 0.411 PngImagePlugin.py:1233(_save) 2 0.000 0.000 0.822 0.411 ImageFile.py:517(_save) 2 0.000 0.000 0.821 0.411 ImageFile.py:545(_encode_tile) 589 0.803 0.001 0.803 0.001 {method 'encode' of 'ImagingEncoder' objects} ``` This is of course only a test as it passes through all `numpy` arrays irrespective of if they should be an image. Also I guess `cast_storage` is meant for casting `pyarrow` storage exclusively. Converting to `pyarrow` array seems like a good solution as it also handles `pytorch` tensors etc., maybe there is a more efficient way to create a PIL image from a `pyarrow` array? Not sure how this should be handled but I would be happy to help if there is a good solution. ### Environment info - `datasets` version: 2.18.1.dev0 - Platform: Linux-6.7.11-200.fc39.x86_64-x86_64-with-glibc2.38 - Python version: 3.12.2 - `huggingface_hub` version: 0.22.2 - PyArrow version: 15.0.2 - Pandas version: 2.2.1 - `fsspec` version: 2024.3.1

Inferring the type seems to be unnecessary given that the pyarrow array has already been created. Because pyarrow array creation is sometimes extremely slow this doubles the time write_batch takes.

Updates the `wmt_t2t` test to pin the `revision` to the version with a loading script (cc @albertvillanova). Additionally, it replaces the occurrences of the `lhoestq/test` repo id with `hf-internal-testing/dataset_with_script` and re-enables logging checks in the `Dataset.from_sql` tests.

`diffusers` (https://github.com/huggingface/diffusers/pull/7116) and `huggingface_hub` (https://github.com/huggingface/huggingface_hub/pull/2072) also use `uv` to install their dependencies, so we can do the same here. It seems to make the "Install dependencies" step in the `ubuntu` jobs 5-8x faster and 1.5-2x in the `windows` one. Besides introducing `uv` in CI, this PR bumps the `tensorflow` minimal version requirement to align with Transformers and simplifies the SpaCy hashing tests (use blank language models instead of the pre-trained ones)

### Describe the bug The `to_csv()` method does not output commas in lists. So when the Dataset is loaded back in the data structure of the column with a list is not correct. Here's an example: Obviously, it's not as trivial as inserting commas in the list, since its a comma-separated file. But hopefully there's a way to export the list in a way that it'll be imported by `load_dataset()` correctly. ### Steps to reproduce the bug Here's some code to reproduce the bug: ```python from datasets import Dataset ds = Dataset.from_dict( { "pokemon": ["bulbasaur", "squirtle"], "type": ["grass", "water"] } ) def ascii_to_hex(text): return [ord(c) for c in text] ds = ds.map(lambda x: {"int": ascii_to_hex(x['pokemon'])}) ds.to_csv('../output/temp.csv') ``` temp.csv then contains: ``` ### Expected behavior ACTUAL OUTPUT: ``` pokemon,type,int bulbasaur,grass,[ 98 117 108 98 97 115 97 117 114] squirtle,water,[115 113 117 105 114 116 108 101] ``` EXPECTED OUTPUT: ``` pokemon,type,int bulbasaur,grass,[98, 117, 108, 98, 97, 115, 97, 117, 114] squirtle,water,[115, 113, 117, 105, 114, 116, 108, 101] ``` or probably something more like this since it's a CSV file: ``` pokemon,type,int bulbasaur,grass,"[98, 117, 108, 98, 97, 115, 97, 117, 114]" squirtle,water,"[115, 113, 117, 105, 114, 116, 108, 101]" ``` ### Environment info ### Package Version Name: datasets Version: 2.16.1 ### Python version: 3.10.12 ### OS Info PRETTY_NAME="Ubuntu 22.04.4 LTS" NAME="Ubuntu" VERSION_ID="22.04" VERSION="22.04.4 LTS (Jammy Jellyfish)" VERSION_CODENAME=jammy ID=ubuntu ID_LIKE=debian ...

The notebook I am using for this can be found [here](https://github.com/GoogleCloudPlatform/vertex-ai-samples/blob/main/notebooks/community/model_garden/model_garden_pytorch_llama2_peft_finetuning.ipynb). When I use the dataset given in the example, the training gets successfully completed (example dataset can be found [here](https://huggingface.co/datasets/timdettmers/openassistant-guanaco)). However when I use my own dataset which is in the same format as the example dataset, I get the below error (my dataset can be found [here](https://huggingface.co/datasets/kk2491/finetune_dataset_002)). ![image](https://github.com/huggingface/datasets/assets/38481564/47fa2de3-95e0-478b-a35f-58cbaf90427a) I see the files are being read correctly from the logs: ![image](https://github.com/huggingface/datasets/assets/38481564/b0b6316c-2cc7-476c-9674-ca2222c8f4e3) ### Steps to reproduce the bug 1.

### Describe the bug Hi, I have a dataset on the hub [here](https://huggingface.co/datasets/manestay/borderlines). It has 1k+ downloads, which I sure is mostly just me and my colleagues working with it. It should have far fewer, since I'm using the same machine with a properly set up HF_HOME variable. However, whenever I run the below function `load_borderlines_hf`, it downloads the entire dataset from the hub and then does the other logic: https://github.com/manestay/borderlines/blob/4e161f444661e2ebfe643f3fe149d9258d63a57d/run_gpt/lib.py#L80 Let me know what I'm doing wrong here, or if it's a bug with the `datasets` library itself. On the hub I have my data stored in CSVs, but several columns are lists, so that's why I have the code to map splitting on `;`. I looked into dataset loading scripts, but it seemed difficult to set up. I have verified that other `datasets` and `models` on my system are using the cache properly (e.g. I have a 13B parameter model and large datasets, but those are cached and don't redownload). __EDIT: __ as pointed out in the discussion below, it may be the `map()` calls that aren't being cached properly. Supposing the `load_dataset()` retrieve from the cache, then it should be the case that the `map()` calls also retrieve from the cached output. But the `map()` commands re-execute sometimes. ### Steps to reproduce the bug 1. Copy and paste the function from [here](https://github.com/manestay/borderlines/blob/4e161f444661e2ebfe643f3fe149d9258d63a57d/run_gpt/lib.py#L80) (lines 80-100) 2. Run it in Python `load_borderlines_hf(None)` 3. It completes successfully, downloading from HF hub, then doing the mapping logic etc. 4. If you run it again after some time, it will re-download, ignoring the cache ### Expected behavior Re-running the code, which calls `datasets.load_dataset('manestay/borderlines', 'territories')`, should use the cached version ### Environment info - `datasets` version: 2.16.1 - Platform: Linux-5.14.21-150500.55.7-default-x86_64-with-glibc2.31 - Python version: 3.10.13 - `huggingface_hub` version: 0.20.3 - PyArrow version: 15.0.0 - Pandas version: 1.5.3 - `fsspec` version: 2023.10.0

Appreciate any help in advance!</div> Hi, referring to the discussion title above, after further digging, I think it's an issue within the datasets library. But not quite sure where it is. If you require any more info or actions from me, please let me know. Appreciate any help in advance!

### Describe the bug `Datasets==2.18.0` is not compatible with `fsspec==2023.12.2`. I have to downgrade fsspec to `fsspec==2023.10.0` to make `Datasets==2.18.0` work properly. ### Steps to reproduce the bug To reproduce the bug: 1. Make sure that `Datasets==2.18.0` and `fsspec==2023.12.2`. 2. Run the following code: ``` from datasets import load_dataset dataset = load_dataset("trec") ``` 3.

### Feature request Hi thanks for the library! I would like to have a huggingface Dataset, and one of its column is custom (non-serializable) Python objects. For example, a minimal code: ``` class MyClass: pass dataset = datasets.Dataset.from_list([ dict(a=MyClass(), b='hello'), ]) ``` It gives error: ``` ArrowInvalid: Could not convert <__main__.MyClass object at 0x7a852830d050> with type MyClass: did not recognize Python value type when inferring an Arrow data type ``` I guess it is because Dataset forces to convert everything into arrow format. However, is there any ways to make the scenario work? Thanks! ### Motivation (see above) ### Your contribution Yes, I am happy to PR!

### Describe the bug Here is the full error stack when installing: ``` ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. datasets 2.18.0 requires fsspec[http]<=2024.2.0,>=2023.1.0, but you have fsspec 2024.3.1 which is incompatible. Successfully installed aiobotocore-2.12.1 aioitertools-0.11.0 botocore-1.34.51 fsspec-2024.3.1 jmespath-1.0.1 s3fs-2024.3.1 urllib3-2.0.7 wrapt-1.16.0 ``` When I install with pip, pip allows this error to exist while still installing s3fs, but this error breaks poetry, since poetry will refuse to install s3fs because of the dependency conflict. Maybe I'm missing something so maybe it's not a bug but some mistake on my end? Any input would be helpful. Thanks! ### Steps to reproduce the bug 1. conda create -n tmp python=3.10 -y 2. conda activate tmp 3. pip install datasets 4. pip install s3fs ### Expected behavior I would expect there to be no error. ### Environment info MacOS (ARM), Python3.10, conda 23.11.0.

### Feature request Enable the `load_dataset` function to load local datasets with symbolic links. E.g, this dataset can be loaded: ├── example_dataset/ │ ├── data/ │ │ ├── train/ │ │ │ ├── file0 │ │ │ ├── file1 │ │ ├── dev/ │ │ │ ├── file2 │ │ │ ├── file3 │ ├── metadata.csv while this dataset can't: ├── example_dataset_symlink/ │ ├── data/ │ │ ├── train/ │ │ │ ├── sym0 -> file0 │ │ │ ├── sym1 -> file1 │ │ ├── dev/ │ │ │ ├── sym2 -> file2 │ │ │ ├── sym3 -> file3 │ ├── metadata.csv I have created an example dataset in order to reproduce the problem: 1. Unzip `example_dataset.zip`. 2. Run `no_symlink.sh`. Training should start without issues. 3. Run `symlink.sh`. You will see that all four examples will be in train split, instead of having two examples in train and two examples in dev. The script won't load the correct audio files. [example_dataset.zip](https://github.com/huggingface/datasets/files/14807053/example_dataset.zip) ### Motivation I have a very large dataset locally. Instead of initiating training on the entire dataset, I need to start training on smaller subsets of the data. Due to the purpose of the experiments I am running, I will need to create many smaller datasets with overlapping data. Instead of copying the all the files for each subset, I would prefer copying symbolic links of the data. This way, the memory usage would not significantly increase beyond the initial dataset size. Advantages of this approach: - It would leave a smaller memory footprint on the hard drive - Creating smaller datasets would be much faster ### Your contribution I would gladly contribute, if this is something useful to the community. It seems like a simple change of code, something like `file_path = os.path.realpath(file_path)` should be added before loading the files. If anyone has insights on how to incorporate this functionality, I would greatly appreciate your knowledge and input.

When a dataset with upper-cases in its name is first loaded using `load_dataset()`, the local cache directory is created with all lowercase letters. However, upon subsequent loads, the current version attempts to locate the cache directory using the dataset's original name, which includes uppercase letters. This discrepancy can lead to confusion and, particularly in offline mode, results in errors. ### Reproduce ```bash ~$ python Python 3.9.19 (main, Mar 21 2024, 17:11:28) [GCC 11.2.0] :: Anaconda, Inc. on linux Type "help", "copyright", "credits" or "license" for more information. >>> from datasets import load_dataset >>> dataset = load_dataset("locuslab/TOFU", "full") >>> quit() ~$ export HF_DATASETS_OFFLINE=1 ~$ python Python 3.9.19 (main, Mar 21 2024, 17:11:28) [GCC 11.2.0] :: Anaconda, Inc. on linux Type "help", "copyright", "credits" or "license" for more information. >>> from datasets import load_dataset >>> dataset = load_dataset("locuslab/TOFU", "full") Traceback (most recent call last): File "<stdin>", line 1, in <module> File "xxxxxx/anaconda3/envs/llm/lib/python3.9/site-packages/datasets/load.py", line 2556, in load_dataset builder_instance = load_dataset_builder( File "xxxxxx/anaconda3/envs/llm/lib/python3.9/site-packages/datasets/load.py", line 2228, in load_dataset_builder dataset_module = dataset_module_factory( File "xxxxxx/anaconda3/envs/llm/lib/python3.9/site-packages/datasets/load.py", line 1871, in dataset_module_factory raise ConnectionError(f"Couldn't reach the Hugging Face Hub for dataset '{path}': {e1}") from None ConnectionError: Couldn't reach the Hugging Face Hub for dataset 'locuslab/TOFU': Offline mode is enabled. >>> ``` I fix this issue by lowering the dataset name (`.lower()`) when generating cache_dir.

I was trying out polars as an output for a map function and found that it wasn't a valid return type in `validate_function_output`. Thought that we should accommodate this by creating and adding it to the `allowed_processed_input_types` variable.

What does this PR do? 1. remove `list_files_info` in favor of `list_repo_tree`. As of `0.23`, `list_files_info` will be removed for good. `datasets` had a utility to support both pre-0.20 and post-0.20 versions. Since `hfh` version is already pinned to `>=0.21.2`, I removed the legacy part. 2. `preupload_lfs_files` had also a different behavior between `<0.20` and `>=0.20`. I remove it since huggingface_hub is now pinned to `>=0.21.2` 3. `hf_hub_url` is overwritten to default to the dataset repo_type. I do think it is misleading to keep the same method naming for it. I renamed it to `get_dataset_url` for clarity. Let me know if you prefer to see this change reverted.

### Feature request Running .map and filter functions with `num_procs` consecutively instantiates several multiprocessing pools iteratively. As instantiating a Pool is very resource intensive it can be a bottleneck to performing iteratively filtering. My ideas: 1. There should be an option to declare `persistent_workers` similar to pytorch DataLoader. Downside would be that would be complex to determine the correct resource allocation and deallocation of the pool. i.e. the dataset can outlive the utility of the pool. 2. Provide a pool as an argument. Downside would be the expertise required by the user. Upside, is that there is better resource management. ### Motivation Is really slow to iteratively perform map and filter operations on a dataset. ### Your contribution If approved I could integrate it. I would need to know what method would be most suitable to implement from the two options above.

Passing `sample_by` to `load_dataset` when loading text data does not work

### Describe the bug I have a dataset that consists of a bunch of text files, each representing an example. There is an undocumented `sample_by` argument for the `TextConfig` class that is used by `Text` to decide whether to split files into lines, paragraphs or take them whole. Passing `sample_by=“document”` to `load_dataset` results in files getting split into lines regardless. I have edited `src/datasets/packaged_modules/text/text.py` for myself to switch the default and it works fine. As a side note, the `if-else` for `sample_by` will silently load an empty dataset if someone makes a typo in the argument, which is not ideal. ### Steps to reproduce the bug 1. Prepare data as a bunch of files in a directory. 2. Load that data via `load_dataset(“text”, data_files=<data_dir>/<files_glob>, …, sample_by=“document”)`. 3. Inspect the resultant dataset — every item should have the form of `{“text”: <a line from a file>}`. ### Expected behavior `load_dataset(“text”, data_files=<data_dir>/<files_glob>, …, sample_by=“document”)` should result in a dataset with items of the form `{“text”: <one document>}`. ### Environment info - `datasets` version: 2.18.0 - Platform: Linux-5.15.0-1046-nvidia-x86_64-with-glibc2.35 - Python version: 3.11.8 - `huggingface_hub` version: 0.21.4 - PyArrow version: 15.0.2 - Pandas version: 2.2.1 - `fsspec` version: 2024.2.0

Related to https://github.com/huggingface/doc-builder/pull/487 and [internal slack thread](https://huggingface.slack.com/archives/C04F8N7FQNL/p1711384899462349?thread_ts=1711041424.720769&cid=C04F8N7FQNL). There is now a `custom_container` option when building docs in CI. When set to `""` (instead of `"huggingface/transformers-doc-builder"` by default), we don't run the CI inside a container, therefore saving ~2min of download time. The plan is to test disabling the transformers container on a few "big" repo and if everything works correctly, we will stop making it the default container.

### Feature request Support loading a dataset from a SQLite file https://huggingface.co/datasets/severo/test_iris_sqlite/tree/main ### Motivation SQLite is a popular file format. ### Your contribution See discussion on slack: https://huggingface.slack.com/archives/C04L6P8KNQ5/p1702481859117909 (internal) In particular: a SQLite file can contain multiple tables, which might be matched to multiple configs. Maybe the detail of splits and configs should be defined in the README YAML, or use the same format as for ZIP files: `Iris.sqlite::Iris`. See dataset here: https://huggingface.co/datasets/severo/test_iris_sqlite Note: should we also support DuckDB files?

### Describe the bug I'm loading a HuggingFace Dataset for images. I'm running a preprocessing (map operation) step that runs a few operations, one of them being conversion to float16. The Dataset features also say that the 'img' is of type float16. Whenever I take an image from that HuggingFace Dataset instance, the type turns out to be float32. ### Steps to reproduce the bug ```python import torchvision.transforms.v2 as transforms from datasets import load_dataset dataset = load_dataset('cifar10', split='test') dataset = dataset.with_format("torch") data_transform = transforms.Compose([transforms.Resize((32, 32)), transforms.ToDtype(torch.float16, scale=True), transforms.Normalize([0.5, 0.5, 0.5], [0.5, 0.5, 0.5]), ]) def _preprocess(examples): # Permutes from (BS x H x W x C) to (BS x C x H x W) images = torch.permute(examples['img'], (0, 3, 2, 1)) examples['img'] = data_transform(images) return examples dataset = dataset.map(_preprocess, batched=True, batch_size=8) ``` Now at this point the dataset.features are showing float16 which is great because that's what I want. ```python print(data_loader.features['img']) Sequence(feature=Sequence(feature=Sequence(feature=Value(dtype='float16', id=None), length=-1, id=None), length=-1, id=None), length=-1, id=None) ``` But when I try to sample an image from this dataloader; I'm getting a float32 image, when I'm expecting float16: ```python print(next(iter(data_loader))['img'].dtype) torch.float32 ``` ### Expected behavior I'm expecting the images loaded after the transformation to stay in float16. ### Environment info - `datasets` version: 2.18.0 - Platform: Linux-5.15.146.1-microsoft-standard-WSL2-x86_64-with-glibc2.31 - Python version: 3.10.9 - `huggingface_hub` version: 0.21.4 - PyArrow version: 14.0.2 - Pandas version: 2.0.3 - `fsspec` version: 2023.10.0

Is it possible this has happened again? ### Steps to reproduce the bug ``` >>> import datasets >>> datasets.load_dataset("hh-rlhf") Repo card metadata block was not found.

### Describe the bug I have loaded a dataset, and then slice first 300 samples using `:` ops, however, the resulting dataset is not expected, as the output below: ```bash len(dataset)=1050324 len(dataset[:300])=2 len(dataset[0:300])=2 len(dataset.select(range(300)))=300 ``` ### Steps to reproduce the bug load a dataset then: ```bash dataset = load_from_disk(args.train_data_dir) print(f"{len(dataset)=}", flush=True) print(f"{len(dataset[:300])=}", flush=True) print(f"{len(dataset[0:300])=}", flush=True) print(f"{len(dataset.select(range(300)))=}", flush=True) ``` ### Expected behavior ```bash len(dataset)=1050324 len(dataset[:300])=300 len(dataset[0:300])=300 len(dataset.select(range(300)))=300 ``` ### Environment info - `datasets` version: 2.16.1 - Platform: Linux-5.15.0-60-generic-x86_64-with-glibc2.35 - Python version: 3.10.11 - `huggingface_hub` version: 0.20.2 - PyArrow version: 10.0.1 - Pandas version: 1.5.3 - `fsspec` version: 2023.10.0

Option to disable file locking

### Feature request Commands such as `load_dataset` creates file locks with `filelock.FileLock`. It would be good if there was a way to disable this. ### Motivation File locking doesn't work on all file-systems (in my case NFS mounted Weka). If the `cache_dir` only had small files then it would be possible to point to local disk and the problem would be solved. However, as cache_dir is both where the small info files are written and the processed datasets are put this isn't a feasible solution. Considering https://github.com/huggingface/datasets/issues/6395 I still do think this is something that belongs in HuggingFace. The possibility to control packages separately is valuable. It might be that a user has their dataset on a file-system that doesn't support file-locking while they are using file locking on local disk to control some other type of access. ### Your contribution My suggested solution: ``` diff --git a/src/datasets/utils/_filelock.py b/src/datasets/utils/_filelock.py index 19620e6e..58f41a02 100644 --- a/src/datasets/utils/_filelock.py +++ b/src/datasets/utils/_filelock.py @@ -18,11 +18,15 @@ import os from filelock import FileLock as FileLock_ -from filelock import UnixFileLock +from filelock import SoftFileLock, UnixFileLock from filelock import __version__ as _filelock_version from packaging import version +if os.getenv('HF_USE_SOFTFILELOCK', 'false').lower() in ('true', '1'): + FileLock_ = SoftFileLock + + class FileLock(FileLock_): """ A `filelock.FileLock` initializer that handles long paths. ```

Support for loading geotiff files as a part of the ImageFolder

### Feature request Request for adding rasterio support to load geotiff as a part of ImageFolder, instead of using PIL ### Motivation As of now, there are many datasets in HuggingFace Hub which are predominantly focussed towards RemoteSensing or are from RemoteSensing. The current ImageFolder (if I have understood correctly) uses PIL. This is not really optimized because mostly these datasets have images with many channels and additional metadata. Using PIL makes one loose it unless we provide a custom script. Hence, maybe an API could be added to have this in common? ### Your contribution If the issue is accepted - i can contribute the code, because I would like to have it automated and generalised.

When i try to create a `Dataset` object with None values inside a dict column, like this: ```python from datasets import Dataset, Features, Value Dataset.from_dict( { "dict": [{"a": 0, "b": 0}, None], }, features=Features( {"dict": {"a": Value("int16"), "b": Value("int16")}} ) ) ``` i get `ValueError: Got None but expected a dictionary instead`. At the same time, having None in _nested_ dict feature works, for example, this doesn't throw any errors: ```python from datasets import Dataset, Features, Value, Sequence dataset = Dataset.from_dict( { "list_dict": [[{"a": 0, "b": 0}], None], "sequence_dict": [[{"a": 0, "b": 0}], None], }, features=Features({ "list_dict": [{"a": Value("int16"), "b": Value("int16")}], "sequence_dict": Sequence({"a": Value("int16"), "b": Value("int16")}), }) ) ``` Other types of features also seem to be nullable (but I haven't checked all of them). Version of `datasets` is the latest atm (2.18.0) Is this an expected behavior or a bug?

### Feature request I'm a huge fan of the current HF Datasets `webdataset` integration (especially the built-in streaming support). However, I'd love to upload some robotics and multimodal datasets I've processed for use with [Mosaic Streaming](https://docs.mosaicml.com/projects/streaming/en/stable/), specifically their [MDS Format](https://docs.mosaicml.com/projects/streaming/en/stable/fundamentals/dataset_format.html#mds). Because the shard files have similar semantics to WebDataset, I'm hoping that adding such support won't be too much trouble? ### Motivation One of the downsides with WebDataset is a lack of out-of-the-box determinism (especially for large-scale training and reproducibility), easy job resumption, and the ability to quickly debug / visualize individual examples. Mosaic Streaming provides a [great interface for this out of the box](https://docs.mosaicml.com/projects/streaming/en/stable/#key-features), so I'd love to see it supported in HF Datasets. ### Your contribution Happy to help test things / provide example data. Can potentially submit a PR if maintainers could point me to the necessary WebDataset logic / steps for adding a new streaming format!

### Describe the bug Mapped tokenization slows down substantially towards end of dataset. train set started off very slow, caught up to 20k then tapered off til the end. what's particularly strange is that the tokenization crashed a few times before due to errors with invalid tokens somewhere or corrupted downloads, and the speed ups/downs consistently happened the same times ```bash Running tokenizer on dataset (num_proc=48): 0%| | 847000/881416735 [12:18<252:45:45, 967.72 examples/s] Running tokenizer on dataset (num_proc=48): 0%| | 848000/881416735 [12:19<224:16:10, 1090.66 examples/s] Running tokenizer on dataset (num_proc=48): 10%|▉ | 84964000/881416735 [3:48:00<11:21:34, 19476.01 examples/s] Running tokenizer on dataset (num_proc=48): 10%|▉ | 84967000/881416735 [3:48:00<12:04:01, 18333.79 examples/s] Running tokenizer on dataset (num_proc=48): 61%|██████ | 538631977/881416735 [13:46:40<27:50:04, 3420.84 examples/s] Running tokenizer on dataset (num_proc=48): 61%|██████ | 538632977/881416735 [13:46:40<23:48:20, 3999.77 examples/s] Running tokenizer on dataset (num_proc=48): 100%|█████████▉| 881365886/881416735 [38:30:19<04:34, 185.10 examples/s] Running tokenizer on dataset (num_proc=48): 100%|█████████▉| 881366886/881416735 [38:30:25<04:36, 180.57 examples/s] ``` and validation set as well ```bash Running tokenizer on dataset (num_proc=48): 90%|████████▉ | 41544000/46390354 [28:44<02:37, 30798.76 examples/s] Running tokenizer on dataset (num_proc=48): 90%|████████▉ | 41550000/46390354 [28:44<02:08, 37698.08 examples/s] Running tokenizer on dataset (num_proc=48): 96%|█████████▋| 44747422/46390354 [2:15:48<12:22:44, 36.87 examples/s] Running tokenizer on dataset (num_proc=48): 96%|█████████▋| 44747422/46390354 [2:16:00<12:22:44, 36.87 examples/s] ``` ### Steps to reproduce the bug using the following kwargs ```python with accelerator.main_process_first(): lm_datasets = tokenized_datasets.map( group_texts, batched=True, num_proc=48 load_from_cache_file=True, desc=f"Grouping texts in chunks of {block_size}", ) ``` running through slurm script ```bash #SBATCH --partition=gpu-nvidia-a100 #SBATCH --nodes=1 #SBATCH --ntasks=1 #SBATCH --gpus-per-task=8 #SBATCH --cpus-per-task=96 ``` using this dataset https://huggingface.co/datasets/togethercomputer/RedPajama-Data-1T ### Expected behavior Constant speed throughout ### Environment info - `datasets` version: 2.15.0 - Platform: Linux-5.15.0-1049-aws-x86_64-with-glibc2.10 - Python version: 3.8.18 - `huggingface_hub` version: 0.19.4 - PyArrow version: 14.0.1 - Pandas version: 2.0.3 - `fsspec` version: 2023.10.0

### Describe the bug I am using a cluster that does not have access to the internet when given a job. I tried downloading the dataset using the huggingface-cli command and then loading it with load_dataset but I get an error: ```raise EmptyDatasetError(f"The directory at {base_path} doesn't contain any data files") from None``` The dataset I'm using is "lmsys/chatbot_arena_conversations". The folder structure is - README.md - data - train-00000-of-00001-cced8514c7ed782a.parquet ### Steps to reproduce the bug 1. Download dataset using HuggingFace CLI: ```huggingface-cli download lmsys/chatbot_arena_conversations --local-dir ./lmsys/chatbot_arena_conversations``` 2. In Python ``` from datasets import load_dataset load_dataset("lmsys/chatbot_arena_conversations") ``` ### Expected behavior Should return a Dataset Dict in the form of ``` DatasetDict({ train: Dataset({ features: [...], num_rows: 33,000 }) }) ``` ### Environment info Python 3.11.5 Datasets 2.18.0 Transformers 4.38.2 Pytorch 2.2.0 Pyarrow 15.0.1 Rocky Linux release 8.9 (Green Obsidian)

### Describe the bug ### My Code ``` from datasets import load_dataset res=[] for i in [0,1]: di=load_dataset( "json", data_files='path_to.json', split='train', streaming=True, ).map(lambda x: {"source": i}) res.append(di) for e in res[0]: print(e) ``` ### Unexpected Behavior Data in `res[0]` has `source=1`. However the expected value is 0. ### FYI I further switch `streaming` to `False`. And the output value is as expected (0). So there may exist bugs in setting `streaming=True` in a for loop. ### Environment Python 3.8.0 datasets==2.18.0 transformers==4.28.1 ### Steps to reproduce the bug 1. Create a Json file with any content. 2. Run the provided code. 3. Switch `streaming` to `False` and run again to see the expected behavior. ### Expected behavior The expected behavior is the data are mapped with its corresponding value in the for loop. ### Environment info Python 3.8.0 datasets==2.18.0 transformers==4.28.1 Ubuntu 20.04

The Pandas packaged builder is undocumented and relies on `pickle` to read the data, making it **unsafe**. Moreover, I haven't seen a single instance of this builder being used (not even using the GH/Hub search), so we should deprecate it.

### Describe the bug This bug is triggered under the following conditions: - datasets repo ids without organization names trigger errors, such as `bookcorpus`, `gsm8k`, `wikipedia`, rather than in the form of `A/B`. - If `HF_ENDPOINT` is set and the hostname is not in the form of `(hub-ci.)?huggingface.co`. - This issue occurs with `datasets>2.15.0` or `huggingface-hub>0.19.4`. For example, using the latest versions: `datasets==2.18.0` and `huggingface-hub==0.21.4`, ### Steps to reproduce the bug the issue can be reproduced with the following code: 1. install specific datasets and huggingface_hub. ```bash pip install datasets==2.18.0 pip install huggingface_hub==0.21.4 ``` 2. execute python code. ```Python import os os.environ['HF_ENDPOINT'] = 'https://hf-mirror.com' from datasets import load_dataset bookcorpus = load_dataset('bookcorpus', split='train') ``` console output: ``` Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/padeoe/.local/lib/python3.10/site-packages/datasets/load.py", line 2556, in load_dataset builder_instance = load_dataset_builder( File "/home/padeoe/.local/lib/python3.10/site-packages/datasets/load.py", line 2228, in load_dataset_builder dataset_module = dataset_module_factory( File "/home/padeoe/.local/lib/python3.10/site-packages/datasets/load.py", line 1879, in dataset_module_factory raise e1 from None File "/home/padeoe/.local/lib/python3.10/site-packages/datasets/load.py", line 1830, in dataset_module_factory with fs.open(f"datasets/{path}/{filename}", "r", encoding="utf-8") as f: File "/home/padeoe/.local/lib/python3.10/site-packages/fsspec/spec.py", line 1295, in open self.open( File "/home/padeoe/.local/lib/python3.10/site-packages/fsspec/spec.py", line 1307, in open f = self._open( File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/hf_file_system.py", line 228, in _open return HfFileSystemFile(self, path, mode=mode, revision=revision, block_size=block_size, **kwargs) File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/hf_file_system.py", line 615, in __init__ self.resolved_path = fs.resolve_path(path, revision=revision) File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/hf_file_system.py", line 180, in resolve_path repo_and_revision_exist, err = self._repo_and_revision_exist(repo_type, repo_id, revision) File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/hf_file_system.py", line 117, in _repo_and_revision_exist self._api.repo_info(repo_id, revision=revision, repo_type=repo_type) File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/utils/_validators.py", line 118, in _inner_fn return fn(*args, **kwargs) File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/hf_api.py", line 2413, in repo_info return method( File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/utils/_validators.py", line 118, in _inner_fn return fn(*args, **kwargs) File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/hf_api.py", line 2286, in dataset_info hf_raise_for_status(r) File "/home/padeoe/.local/lib/python3.10/site-packages/huggingface_hub/utils/_errors.py", line 362, in hf_raise_for_status raise HfHubHTTPError(str(e), response=response) from e huggingface_hub.utils._errors.HfHubHTTPError: 401 Client Error: Unauthorized for url: https://hf-mirror.com/api/datasets/bookcorpus/bookcorpus.py (Request ID: Root=1-65ee8659-5ab10eec5960c63e71f2bb58;b00bdbea-fd6e-4a74-8fe0-bc4682ae090e) ``` ### Expected behavior The dataset was downloaded correctly without any errors. ### Environment info datasets==2.18.0 huggingface-hub==0.21.4

Hello, When working with bio-data, each feature often has metadata associated with it (e.g. species, lineage, snp position, etc). To store this, I like to use the feature classes with the added `metadata` attribute. However, when saving or loading with custom features, you get an error since that class doesn't exist in the global namespace in `datasets.features.features`. Take for example, ```python from dataclasses import dataclass, field from datasets import Dataset from datasets.features.features import Value, Features @dataclass class FeatureA(Value): metadata: dict = field(default=dict) _type: str = field(default="FeatureA", init=False, repr=False) @dataclass class FeatureB(Value): metadata: dict = field(default_factory=dict) _type: str = field(default="FeatureB", init=False, repr=False) test_data = { "a": [1, 2, 3], "b": [4, 5, 6], } test_data = Dataset.from_dict( test_data, features=Features({ "a": FeatureA("int32", metadata={"species": "lactobacillus acetotolerans"}), "b": FeatureB("int32", metadata={"species": "lactobacillus iners"}), }) ) # returns an error since FeatureA and FeatureB are not in the global namespace test_data.save_to_disk('./test_data') ``` Saving the dataset (0/1 shards): 0%| | 0/3 [00:00<?, ? examples/s] --------------------------------------------------------------------------- KeyError Traceback (most recent call last) Cell In[2], line 28 19 test_data = Dataset.from_dict( 20 test_data, 21 features=Features({ (...) 24 }) 25 ) 27 # returns an error since FeatureA and FeatureB are not in the global namespace ---> 28 test_data.save_to_disk('./test_data') ... File ~\Documents\datasets\src\datasets\features\features.py:1361, in generate_from_dict(obj) 1359 return {key: generate_from_dict(value) for key, value in obj.items()} 1360 obj = dict(obj) -> 1361 class_type = globals()[obj.pop("_type")] 1363 if class_type == Sequence: 1364 return Sequence(feature=generate_from_dict(obj["feature"]), length=obj.get("length", -1)) KeyError: 'FeatureA' We can avoid this by having a registry (like formatters) and doing ```python from datasets.features.features import register_feature register_feature(FeatureA, "FeatureA") register_feature(FeatureB, "FeatureB") test_data.save_to_disk('./test_data') ``` Saving the dataset (1/1 shards): 100%|------| 3/3 [00:00<00:00, 211.13 examples/s] and loading from disk returns with all metadata information ```python from datasets import load_from_disk test_data = load_from_disk('./test_data') test_data.features ``` {'a': FeatureA(dtype='int32', id=None, metadata={'species': 'lactobacillus acetotolerans'}), 'b': FeatureB(dtype='int32', id=None, metadata={'species': 'lactobacillus iners'})}

### Describe the bug # Let's make it faster First, an evidence... ![image](https://github.com/huggingface/datasets/assets/159512661/a703a82c-43a0-426c-9d99-24c563d70965) Figure 1: CProfile for loading 3 files from cerebras/SlimPajama-627B train split, and 3 files from test split using streaming=True. X axis is 1106 seconds long. See? It's pretty slow. What is resolve pattern doing? ``` resolve_pattern called with **/train/** and hf://datasets/cerebras/SlimPajama-627B@2d0accdd58c5d5511943ca1f5ff0e3eb5e293543 resolve_pattern took 20.815081119537354 seconds ``` Makes sense. How to improve it? ## Bigger project, biggest payoff Databricks (and consequently, spark) store a compressed manifest file of the files contained in the remote filesystem. Then, you download one tiny file, decompress it, and all the operations are local instead of this shenanigans. It seems pretty straightforward to make dataset uploads compute a manifest and upload it alongside their data. This would make resolution time so fast that nobody would ever think about it again. It also means you either need to have the uploader compute it _every time_, or have a hook that computes it. ## Smaller project, immediate payoff: Be diligent in avoiding deepcopy Revise the _ls_tree method to avoid deepcopy: ``` def _ls_tree( self, path: str, recursive: bool = False, refresh: bool = False, revision: Optional[str] = None, expand_info: bool = True, ): ..... omitted ..... for path_info in tree: if isinstance(path_info, RepoFile): cache_path_info = { "name": root_path + "/" + path_info.path, "size": path_info.size, "type": "file", "blob_id": path_info.blob_id, "lfs": path_info.lfs, "last_commit": path_info.last_commit, "security": path_info.security, } else: cache_path_info = { "name": root_path + "/" + path_info.path, "size": 0, "type": "directory", "tree_id": path_info.tree_id, "last_commit": path_info.last_commit, } parent_path = self._parent(cache_path_info["name"]) self.dircache.setdefault(parent_path, []).append(cache_path_info) out.append(cache_path_info) return copy.deepcopy(out) # copy to not let users modify the dircache ``` Observe this deepcopy at the end. It is making a copy of a very simple data structure. We do not need to copy. We can simply generate the data structure twice instead. It will be much faster. ``` def _ls_tree( self, path: str, recursive: bool = False, refresh: bool = False, revision: Optional[str] = None, expand_info: bool = True, ): ..... omitted ..... def make_cache_path_info(path_info): if isinstance(path_info, RepoFile): return { "name": root_path + "/" + path_info.path, "size": path_info.size, "type": "file", "blob_id": path_info.blob_id, "lfs": path_info.lfs, "last_commit": path_info.last_commit, "security": path_info.security, } else: return { "name": root_path + "/" + path_info.path, "size": 0, "type": "directory", "tree_id": path_info.tree_id, "last_commit": path_info.last_commit, } for path_info in tree: cache_path_info = make_cache_path_info(path_info) out_cache_path_info = make_cache_path_info(path_info) # copy to not let users modify the dircache parent_path = self._parent(cache_path_info["name"]) self.dircache.setdefault(parent_path, []).append(cache_path_info) out.append(out_cache_path_info) return out ``` Note there is no longer a deepcopy in this method. We have replaced it with generating the output twice. This is substantially faster. For me, the entire resolution went from 1100s to 360s. ## Medium project, medium payoff After the above change, we have this profile: ![image](https://github.com/huggingface/datasets/assets/159512661/db7b83da-2dfc-4c2e-abab-0ede9477876c) Figure 2: x-axis is 355 seconds. Note that globbing and _ls_tree deep copy is gone. No surprise there. It's much faster now, but we still spend ~187seconds in get_fs_token_paths. Well get_fs_token_paths is part of fsspec. We don't need to fix that because we can trust their developers to write high performance code. Probably the caller has misconfigured something. Let's take a look at the storage_options being provided to the filesystem that is constructed during this call. Ah yes, streaming_download_manager::_prepare_single_hop_path_and_storage_options. We know streaming download manager is not compatible with async right now, but we really need this specific part of the code to be async. We're spending so much time checking isDir on the remote filesystem, it's a huge waste. We can make the call easily 20-30x faster by using async, removing this performance bottleneck almost entirely (and reducing the total time of this part of the code to <30s. There is no reason to block async isDir calls for streaming. I'm not going to mess w/ this one myself; I didn't write the streaming impl, and I don't know how it works, but I know the isDir check can be async. ### Steps to reproduce the bug ``` with cProfile.Profile() as pr: pr.enable() # Begin Data if not os.path.exists(data_cache_dir): os.makedirs(data_cache_dir, exist_ok=True) training_dataset = load_dataset(training_dataset_name, split=training_split, cache_dir=data_cache_dir, streaming=True).take(training_slice) eval_dataset = load_dataset(eval_dataset_name, split=eval_split, cache_dir=data_cache_dir, streaming=True).take(eval_slice) # End Data pr.disable() pr.create_stats() if not os.path.exists(profiling_path): os.makedirs(profiling_path, exist_ok=True) pr.dump_stats(os.path.join(profiling_path, "cprofile.prof")) ``` run this code for "cerebras/SlimPajama-627B" and whatever other params ### Expected behavior Something better. ### Environment info - `datasets` version: 2.18.0 - Platform: Linux-5.15.146.1-microsoft-standard-WSL2-x86_64-with-glibc2.35 - Python version: 3.10.13 - `huggingface_hub` version: 0.21.3 - PyArrow version: 15.0.0 - Pandas version: 2.2.1 - `fsspec` version: 2024.2.0

### Feature request Request for a comparison of huggingface datasets compared with other data format especially webdataset ### Motivation I see huggingface datasets uses Apache Arrow as its backend, it seems to be great, but I'm curious about how it is good compared with other dataset format, like webdataset, what's the pros/cons of them. ### Your contribution More information

Dataset with loading script does not work in renamed repos

### Describe the bug My data repository was first called `BramVanroy/hplt-mono-v1-2` but I then renamed to use underscores instead of dashes. However, it seems that `datasets` retrieves the old repo name when it checks whether the repo contains data loading scripts in this line. https://github.com/huggingface/datasets/blob/6fb6c834f008996c994b0a86c3808d0a33d44525/src/datasets/load.py#L1845 When I print `filename` it returns `hplt-mono-v1-2.py` but the files in the repo are of course `['.gitattributes', 'README.md', 'hplt_mono_v1_2.py']`. So the `filename` is the original reponame instead of the renamed one. I am not sure if this is a caching issue or not or how I can resolve it. ### Steps to reproduce the bug ``` from datasets import load_dataset ds = load_dataset( "BramVanroy/hplt-mono-v1-2", "ky", trust_remote_code=True ) ``` ### Expected behavior That the most recent repo name is used when `filename` is generated. ### Environment info - `datasets` version: 2.16.1 - Platform: Linux-5.14.0-284.25.1.el9_2.x86_64-x86_64-with-glibc2.34 - Python version: 3.10.13 - `huggingface_hub` version: 0.20.2 - PyArrow version: 14.0.1 - Pandas version: 2.1.3 - `fsspec` version: 2023.10.0

### Describe the bug I am trying to get the HPLT datasets on the hub. Downloading/re-uploading would be too time- and resource consuming so I wrote [a dataset loader script](https://huggingface.co/datasets/BramVanroy/hplt_mono_v1_2/blob/main/hplt_mono_v1_2.py). I think I am very close but for some reason I always get the error below. It happens during the clean-up phase where the directory cannot be removed because it is not empty. My only guess would be that this may have to do with zstandard ``` Traceback (most recent call last): File

### Describe the bug I am using an iterable dataset in a multi-node setup, trying to do training/inference while filtering the data on the fly. I usually do not use `split_dataset_by_node` but it is very slow using the IterableDatasetShard in `accelerate` and `transformers`. When I filter after applying `split_dataset_by_node`, it results in shards that are not equal sizes due to unequal samples filtered from each one. The distributed process hangs when trying to accomplish this. Is there any way to resolve this or is it impossible to implement? ### Steps to reproduce the bug Here is a toy example of what I am trying to do that reproduces the behavior ``` # torchrun --nproc-per-node 2 file.py import os import pandas as pd import torch from accelerate import Accelerator from datasets import Features, Value, load_dataset from datasets.distributed import split_dataset_by_node from torch.utils.data import DataLoader accelerator = Accelerator(device_placement=True, dispatch_batches=False) if accelerator.is_main_process: if not os.path.exists("scratch_data"): os.mkdir("scratch_data") n_shards = 4 for i in range(n_shards): df = pd.DataFrame({"id": list(range(10 * i, 10 * (i + 1)))}) df.to_parquet(f"scratch_data/shard_{i}.parquet") world_size = accelerator.num_processes local_rank = accelerator.process_index def collate_fn(examples): input_ids = [] for example in examples: input_ids.append(example["id"]) return torch.LongTensor(input_ids) dataset = load_dataset( "parquet", data_dir="scratch_data", split="train", streaming=True ) dataset = ( split_dataset_by_node(dataset, rank=local_rank, world_size=world_size) .filter(lambda x: x["id"] < 35) .shuffle(seed=42, buffer_size=100) ) batch_size = 2 train_dataloader = DataLoader( dataset, batch_size=batch_size, collate_fn=collate_fn, num_workers=2 ) for x in train_dataloader: x = x.to(accelerator.device) print({"rank": local_rank, "id": x}) y = accelerator.gather_for_metrics(x) if accelerator.is_main_process: print("gathered", y) ``` ### Expected behavior Is there any way to continue training/inference on the GPUs that have remaining data left without waiting for the others? Is it impossible to filter when ### Environment info - `datasets` version: 2.18.0 - Platform: Linux-5.10.209-198.812.amzn2.x86_64-x86_64-with-glibc2.31 - Python version: 3.10.13 - `huggingface_hub` version: 0.21.3 - PyArrow version: 15.0.0 - Pandas version: 2.2.1 - `fsspec` version: 2023.6.0

I was preparing some datasets for AI training and noticed that `datasets` by HuggingFace uses the conventional `open` mechanism to read the file and split it into chunks. I thought it can be significantly accelerated, and [started with a benchmark](https://gist.github.com/ashvardanian/55c2052e9f78b05b8d614aa90cb12347): ```sh $ pip install --upgrade --force-reinstall datasets $ python benchmark_huggingface_datasets.py xlsum.csv Generating train split: 1004598 examples [00:47, 21116.16 examples/s] Time taken to load the dataset: 48.66838526725769 seconds Time taken to chunk the dataset into parts of size 10000: 0.11466407775878906 seconds Total time taken: 48.78304934501648 seconds ``` For benchmarks I've used a [large CSV file with mixed UTF-8 content](https://github.com/ashvardanian/StringZilla/blob/main/CONTRIBUTING.md#benchmarking-datasets), most common in modern large-scale pre-training pipelines. I've later patched the `datasets` library to use `stringzilla`, which resulted in significantly lower memory consumption and in 2.9x throughput improvement on the AWS `r7iz` instances. That's using slow SSDs mounted over the network. Performance on local SSDs on something like a DGX-H100 should be even higher: ```sh $ pip install -e . $ python benchmark_huggingface_datasets.py xlsum.csv Generating train split: 1004598 examples [00:15, 64529.90 examples/s] Time taken to load the dataset: 16.45028805732727 seconds Time taken to chunk the dataset into parts of size 10000: 0.1291060447692871 seconds Total time taken: 16.579394102096558 seconds ``` I've already [pushed the patches to my fork](https://github.com/ashvardanian/datasets/tree/faster-text-parsers), and would love to contribute them to the upstream repository. --- All the tests pass, but they leave a couple of important questions open. The default Python `open(..., newline=None)` uses universal newlines, where `\n`, `\r`, and `\r\n` are all converted to `\n` on the fly. I am not sure if its a good idea for a general purpose dataset preparation pipeline? I can simulate the same behavior (which I don't yet do) for `"line"` splitter. Adjusting it for `"paragraph"`-splitter would be harder. Should we stick exactly to the old Pythonic behavior or stay closer to how C and other programming languages do that?

Use shared memory for the IterableDataset epoch. This way calling `ds.set_epoch()` in the main process will update the epoch in the DataLoader workers as well. This is useful especially because the epoch is used to compute the `effective_seed` used for shuffling. I used torch's shared memory in case users want to send dataset copies without shared memory using pickle. I also find it easier to use than using `multiprocessing.shared_memory` than requires unlinking only in the main process, or `mp.Value` that is not picklable. close https://github.com/huggingface/datasets/issues/6673 cc @rwightman

Separate the default patterns that match directories from the ones matching files and ensure directories are checked first (reverts the change from https://github.com/huggingface/datasets/pull/6244, which merged these patterns). Also, ensure that the glob patterns do not overlap to avoid duplicates in the result. Additionally, replace `get_fs_token_paths` with `url_to_fs` to avoid [unnecessary glob calls](https://github.com/fsspec/filesystem_spec/blob/14dce8ca78f7aa509a20edb263bff83a7760c24d/fsspec/core.py#L655-L656). fix https://github.com/huggingface/datasets/issues/6259 fix https://github.com/huggingface/datasets/issues/6272

### Describe the bug I get the following error message: You are trying to load a dataset that was saved using `save_to_disk`. Please use `load_from_disk` instead. ### Steps to reproduce the bug 1. Save a dataset with `save_to_disk` 2. Try to load it with `load_datasets` ### Expected behavior I am able to load the dataset again with `load_datasets` which most packages uses over `load_from_disk`. I want to have a workaround that allows me to create the same indexing that `push_to_hub` creates for you before using `save_to_disk` - how can that be achieved? ### Environment info datasets 2.17.1, python 3.10

### Feature request Say I have the following code: ``` from datasets import Dataset import pandas as pd new_data = { "column_1": ["value1", "value2"], "column_2": ["value3", "value4"], } df_new = pd.DataFrame(new_data) dataset_new = Dataset.from_pandas(df_new) # add these samples to a remote dataset ``` It would be great to have a way to push dataset_new to a remote dataset that respects the same schema. This way one would not have to do the following: ``` from datasets import load_dataset dataset = load_dataset('username/dataset_name', use_auth_token='your_hf_token_here') updated_dataset = dataset['train'].concatenate(dataset_new) updated_dataset.push_to_hub('username/dataset_name', use_auth_token='your_hf_token_here') ``` ### Motivation No need to download the dataset. ### Your contribution Maybe this feature already exists, didnt see it though. I do not have the expertise to do this.

This allows to stream datasets like [Major-TOM/Core-S2L2A](https://huggingface.co/datasets/Major-TOM/Core-S2L2A) which have row groups with few rows (one row is ~10MB). Previously the cold start would take a lot of time and OOM because it would download many row groups before yielding the first example. I tried on OpenOrca and imagenet-hard and it does't affect overall throughput. Even if the overall throughput doesn't change for datasets like imagenet-hard with big rows, note that it does create shorter and more frequent pauses to download the next row group. Though I find it fine because previously the pauses were less frequent but very long (downloading multiple row groups at a time)
