Why return_tensors='pt' doesn't work？

open

NONE

### Describe the bug I tried to add input_ids to dataset with map(), and I used the return_tensors='pt', but why I got the callback with the type of List？  ### Steps to reproduce the bug  ### Expected behavior Sorry for this silly question, I'm noob on using this tool. But I think it should return a tensor value as I have used the protocol？ When I tokenize only one sentence using tokenized_input=tokenizer(input, return_tensors='pt' )，it does return in tensor type. Why doesn't it work in map()？ ### Environment info transformers>=4.41.2,<=4.45.0 datasets>=2.16.0,<=2.21.0 accelerate>=0.30.1,<=0.34.2 peft>=0.11.1,<=0.12.0 trl>=0.8.6,<=0.9.6 gradio>=4.0.0 pandas>=2.0.0 scipy einops sentencepiece tiktoken protobuf uvicorn pydantic fastapi sse-starlette matplotlib>=3.7.0 fire packaging pyyaml numpy<2.0.0

Specifically, [`Dataset.save_to_disk`](https://huggingface.co/docs/datasets/main/en/package_reference/main_classes#datasets.Dataset.save_to_disk) is a lot slower when using `num_proc>1` than when using `num_proc=1` The documentation mentions that "Multiprocessing is disabled by default.", but there is no explanation on how to enable it. ### Steps to reproduce the bug ``` import numpy as np from datasets import Dataset n_samples = int(4e6) n_tokens_sample = 100 data_dict = { 'tokens' : np.random.randint(0, 100, (n_samples, n_tokens_sample)), } dataset = Dataset.from_dict(data_dict) dataset.save_to_disk('test_dataset', num_proc=1) dataset.save_to_disk('test_dataset', num_proc=4) dataset.save_to_disk('test_dataset', num_proc=8) ``` This results in: ``` >>> dataset.save_to_disk('test_dataset', num_proc=1) Saving the dataset (7/7 shards): 100%|██████████████| 4000000/4000000 [00:17<00:00, 228075.15 examples/s] >>> dataset.save_to_disk('test_dataset', num_proc=4) Saving the dataset (7/7 shards): 100%|██████████████| 4000000/4000000 [01:49<00:00, 36583.75 examples/s] >>> dataset.save_to_disk('test_dataset', num_proc=8) Saving the dataset (8/8 shards): 100%|██████████████| 4000000/4000000 [02:11<00:00, 30518.43 examples/s] ``` With larger datasets it can take hours, but I didn't benchmark that for this bug report. ### Expected behavior I would expect using `num_proc>1` to be faster instead of slower than `num_proc=1`. ### Environment info - `datasets` version: 3.1.0 - Platform: Linux-5.15.153.1-microsoft-standard-WSL2-x86_64-with-glibc2.35 - Python version: 3.10.12 - `huggingface_hub` version: 0.26.2 - PyArrow version: 18.0.0 - Pandas version: 2.2.3 - `fsspec` version: 2024.6.1

NONE

### Describe the bug In [my dataset](https://huggingface.co/datasets/speedcell4/opus-unigram2), there is a column called `lang2`, and there are 94 different classes in total, but the viewer says there are 83 values only. This issue only arises in the `train` split. The total number of values is also 94 in the `test` and `dev` columns, viewer tells the correct number of them. <img width="177" alt="image" src="https://github.com/user-attachments/assets/78d76ef2-fe0e-4fa3-85e0-fb2552813d1c"> ### Steps to reproduce the bug ```python3 from datasets import load_dataset ds = load_dataset('speedcell4/opus-unigram2').unique('lang2') for key, lang2 in ds.items(): print(key, len(lang2)) ``` This script returns the following and tells that the `train` split has 94 values in the `lang2` column. ``` train 94 dev 94 test 94 zero 5 ``` ### Expected behavior 94 in the reviewer. ### Environment info Collecting environment information...

Support for identifier-based automated split construction

open

CONTRIBUTOR

### Feature request As far as I understand, automated construction of splits for hub datasets is currently based on either file names or directory structure ([as described here](https://huggingface.co/docs/datasets/en/repository_structure)) It would seem to be pretty useful to also allow splits to be based on identifiers of individual examples This could be configured like {"split_name": {"column_name": [column values in split]}} (This in turn requires unique 'index' columns, which could be explicitly supported or just assumed to be defined appropriately by the user). I guess a potential downside would be that shards would end up spanning different splits - is this something that can be handled somehow? Would this only affect streaming from hub? ### Motivation The main motivation would be that all data files could be stored in a single directory, and multiple sets of splits could be generated from the same data. This is often useful for large datasets with multiple distinct sets of splits. This could all be configured via the README.md yaml configs ### Your contribution May be able to contribute if it seems like a good idea

Faulty datasets.exceptions.ExpectedMoreSplitsError

open

CONTRIBUTOR

### Describe the bug Trying to download only the 'validation' split of my dataset; instead hit the error `datasets.exceptions.ExpectedMoreSplitsError`. Appears to be the same undesired behavior as reported in [#6939](https://github.com/huggingface/datasets/issues/6939), but with `data_files`, not `data_dir`. Here is the Traceback: ``` Traceback (most recent call last): File "/home/user/app/app.py", line 12, in <module> ds = load_dataset('datacomp/imagenet-1k-random0.0', token=GATED_IMAGENET, data_files={'validation': 'data/val*'}, split='validation', trust_remote_code=True) File "/usr/local/lib/python3.10/site-packages/datasets/load.py", line 2154, in load_dataset builder_instance.download_and_prepare( File "/usr/local/lib/python3.10/site-packages/datasets/builder.py", line 924, in download_and_prepare self._download_and_prepare( File "/usr/local/lib/python3.10/site-packages/datasets/builder.py", line 1018, in _download_and_prepare verify_splits(self.info.splits, split_dict) File "/usr/local/lib/python3.10/site-packages/datasets/utils/info_utils.py", line 68, in verify_splits raise ExpectedMoreSplitsError(str(set(expected_splits) - set(recorded_splits))) datasets.exceptions.ExpectedMoreSplitsError: {'train', 'test'} ``` Note: I am using the `data_files` argument only because I am trying to specify that I only want the 'validation' split, and the whole dataset will be downloaded even when the `split='validation'` argument is specified, unless you also specify `data_files`, as described here: https://discuss.huggingface.co/t/how-can-i-download-a-specific-split-of-a-dataset/79027 ### Steps to reproduce the bug 1. Create a Space with the default blank 'gradio' SDK https://huggingface.co/new-space 2. Create a file 'app.py' that loads a dataset to only extract a 'validation' split: `ds = load_dataset('datacomp/imagenet-1k-random0.0', token=GATED_IMAGENET, data_files={'validation': 'data/val*'}, split='validation', trust_remote_code=True)` ### Expected behavior Downloading validation split. ### Environment info Default environment for creating a new Space. Relevant to this bug, that is: ``` FROM docker.io/library/python:3.10@sha256:fd0fa50d997eb56ce560c6e5ca6a1f5cf8fdff87572a16ac07fb1f5ca01eb608 --> RUN pip install --no-cache-dir pip==22.3.1 && pip install --no-cache-dir datasets "huggingface-hub>=0.19" "hf-transfer>=0.1.4" "protobuf<4" "click<8.1" ```

Add filename in error message when ReadError or similar occur

open

NONE

Please update error messages to include relevant information for debugging when loading datasets with `load_dataset()` that may have a few corrupted files. Whenever downloading a full dataset, some files might be corrupted (either at the source or from downloading corruption). However the errors often only let me know it was a tar file if `tarfile.ReadError` appears on the traceback, and I imagine similarly for other file types. This makes it really hard to debug which file is corrupted, and when dealing with very large datasets, it shouldn't be necessary to force download everything again.

Feature proposal: Stacking, potentially heterogeneous, datasets

open

NONE

### Introduction Hello there, I noticed that there are two ways to combine multiple datasets: Either through `datasets.concatenate_datasets` or `datasets.interleave_datasets`. However, to my knowledge (please correct me if I am wrong) both approaches require the datasets that are combined to have the same features. I think it would be a great idea to add support for combining multiple datasets that might not follow the same schema (i.e. have different features), for example an image and text dataset. That is why I propose a third function of the `datasets.combine` module called `stack_datasets`, which can be used to combine a list of datasets with (potentially) different features. This would look as follows: ```python >>> from datasets import stack_datasets >>> image_dataset = ... >>> next(iter(image_dataset)) {'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=555x416 at 0x313E79CD0> } >>> text_dataset = ... >>> next(iter(text_dataset)) {'text': "This is a test."} >>> stacked = stack_datasets(datasets={'i_ds': image_dataset, 't_ds': text_dataset}, stopping_strategy='all_exhausted') >>> next(iter(stacked)) { 'i_ds': {'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=555x416 at 0x313E79CD0> } 't_ds': {'text': "This is a test."} } ``` <br /> ### Motivation I motivate this by: **A**: The fact that Pytorch offers a similar functionality under `torch.utils.data.StackDataset` ([link](https://pytorch.org/docs/stable/data.html#torch.utils.data.StackDataset)). **B**: In settings where one would like to e.g. train a Vision-Language model using an image-text dataset, an image dataset, and a text dataset, this functionality would offer a clean and intuitive solution to create multimodal datasets. I am aware that the aforementioned is also feasible without my proposed function, but I believe this offers a nice approach that aligns with existing functionality and is directly provided within the `datasets` package. ### API `stack_datasets` has two arguments: `datasets` and `stopping_strategy `. <br /> `datasets` is a dictionary of either type `Dict[str, Dataset]` or `Dict[str, IterableDatasets]`, a mixture is not allowed. It contains the names of the datasets (the keys) and the datasets themselves (the values) that should be stacked. Each item returned is a dictionary with one key-value pair for each dataset. The keys are the names of the datasets as provided in the argument `datasets`, and the values are the respective examples from the datasets. <br /> `stopping_strategy` is the same as for `interleave_datasets`. If it is `first_exhausted` we stop if the smallest dataset runs out of examples, if it is `all_exhausted` we stop if all datasets ran out of examples at least once. For `all_exhausted` that means that we may visit examples from datasets multiple times. ### Docs I saw that there are multiple documentations and guides on the HuggingFace website that introduce `concatenate_datasets` and `interleave_datasets`, for example [here](https://huggingface.co/docs/datasets/process#concatenate). If this request is merged I would be willing to add the new functionality at the appropriate points in the documentation (if desired). ### Tests I also added some tests to ensure correctness. Some tests I wrote in [tests/test_iterable_dataset.py](https://github.com/TimCares/datasets/blob/fadc1159debf2a65d44e40cbf7758f2bd2cc8b08/tests/test_iterable_dataset.py#L2169) run for both `Dataset` and `IterableDataset` even though tests for `Dataset` technically do not belong in this script, but I found that this was a nice way to cover more cases with mostly the same code. ### Additional information I tried to write the code in a way so that it is similar to that of `concatenate_datasets` and `interleave_datasets`. I’m open to feedback and willing to make adjustments based on your suggestions, so feel free to give me your take. :)

### Describe the bug I am performing two operations I see on a hugging face tutorial (Fine-tune a language model), and I am defining every aspect inside the mapped functions, also some imports of the library because it doesnt identify anything not defined outside that function where the dataset elements are being mapped: https://colab.research.google.com/github/huggingface/notebooks/blob/main/examples/language_modeling.ipynb#scrollTo=iaAJy5Hu3l_B `- lm_datasets = tokenized_datasets.map( group_texts, batched=True, batch_size=batch_size, num_proc=4, ) - tokenized_datasets = datasets.map(tokenize_function, batched=True, num_proc=4, remove_columns=["text"]) def tokenize_function(examples): model_checkpoint = 'gpt2' from transformers import AutoTokenizer tokenizer = AutoTokenizer.from_pretrained(model_checkpoint, use_fast=True) return tokenizer(examples["text"])` ### Steps to reproduce the bug Currently handle all the imports inside the function ### Expected behavior The code must work es expected in the notebook, but currently this is not happening. https://colab.research.google.com/github/huggingface/notebooks/blob/main/examples/language_modeling.ipynb#scrollTo=iaAJy5Hu3l_B ### Environment info print(transformers.__version__) 4.46.1

Memory leak when streaming

open

NONE

### Describe the bug I try to use a dataset with streaming=True, the issue I have is that the RAM usage becomes higher and higher until it is no longer sustainable. I understand that huggingface store data in ram during the streaming, and more worker in dataloader there are, more a lot of shard will be stored in ram, but the issue I have is that the ram usage is not constant. So after each new shard loaded, the ram usage will be higher and higher. ### Steps to reproduce the bug You can run this code and see you ram usage, after each shard of 255 examples, your ram usage will be extended. ```py from datasets import load_dataset from torch.utils.data import DataLoader dataset = load_dataset("WaveGenAI/dataset", streaming=True) dataloader = DataLoader(dataset["train"], num_workers=3) for i, data in enumerate(dataloader): print(i, end="\r") ``` ### Expected behavior The Ram usage should be always the same (just 3 shards loaded in the ram). ### Environment info - `datasets` version: 3.0.1 - Platform: Linux-6.10.5-arch1-1-x86_64-with-glibc2.40 - Python version: 3.12.4 - `huggingface_hub` version: 0.26.0 - PyArrow version: 17.0.0 - Pandas version: 2.2.3 - `fsspec` version: 2024.6.1

mismatch for datatypes when providing `Features` with `Array2D` and user specified `dtype` and using with_format("numpy")

### Describe the bug If the user provides a `Features` type value to `datasets.Dataset` with members having `Array2D` with a value for `dtype`, it is not respected during `with_format("numpy")` which should return a `np.array` with `dtype` that the user provided for `Array2D`. It seems for floats, it will be set to `float32` and for ints it will be set to `int64` ### Steps to reproduce the bug ```python import numpy as np import datasets from datasets import Dataset, Features, Array2D print(f"datasets version: {datasets.__version__}") data_info = { "arr_float" : "float64", "arr_int" : "int32" } sample = {key : [np.zeros([4, 5], dtype=dtype)] for key, dtype in data_info.items()} features = {key : Array2D(shape=(None, 5), dtype=dtype) for key, dtype in data_info.items()} features = Features(features) dataset = Dataset.from_dict(sample, features=features) ds = dataset.with_format("numpy") for key in features: print(f"{key} feature dtype: ", ds.features[key].dtype) print(f"{key} dtype:", ds[key].dtype) ``` Output: ```bash datasets version: 3.0.2 arr_float feature dtype: float64 arr_float dtype: float32 arr_int feature dtype: int32 arr_int dtype: int64 ``` ### Expected behavior It should return a `np.array` with `dtype` that the user provided for the corresponding member in the `Features` type value ### Environment info - `datasets` version: 3.0.2 - Platform: Linux-6.11.5-arch1-1-x86_64-with-glibc2.40 - Python version: 3.12.7 - `huggingface_hub` version: 0.26.1 - PyArrow version: 16.1.0 - Pandas version: 2.2.2 - `fsspec` version: 2024.5.0

Add IterableDataset.shard()

closed

MEMBER

Will be useful to distribute a dataset across workers (other than pytorch) like spark I also renamed `.n_shards` -> `.num_shards` for consistency and kept the old name for backward compatibility. And a few changes in internal functions for consistency as well (rank, world_size -> num_shards, index) Breaking change: the new default for `contiguous` in `Dataset.shard()` is `True`, but imo not a big deal since I couldn't find any usage of `contiguous=False` internally (we always do contiguous=True for map-style datasets since its more optimized) or in the wild

How to debugging

open

NONE

### Describe the bug I wanted to use my own script to handle the processing, and followed the tutorial documentation by rewriting the MyDatasetConfig and MyDatasetBuilder (which contains the _info,_split_generators and _generate_examples methods) classes. Testing with simple data was able to output the results of the processing, but when I wished to do more complex processing, I found that I was unable to debug (even the simple samples were inaccessible). There are no errors reported, and I am able to print the _info,_split_generators and _generate_examples messages, but I am unable to access the breakpoints. ### Steps to reproduce the bug # my_dataset.py import json import datasets class MyDatasetConfig(datasets.BuilderConfig): def __init__(self, **kwargs): super(MyDatasetConfig, self).__init__(**kwargs) class MyDataset(datasets.GeneratorBasedBuilder): VERSION = datasets.Version("1.0.0") BUILDER_CONFIGS = [ MyDatasetConfig( name="default", version=VERSION, description="myDATASET" ), ] def _info(self): print("info") # breakpoints return datasets.DatasetInfo( description="myDATASET", features=datasets.Features( { "id": datasets.Value("int32"), "text": datasets.Value("string"), "label": datasets.ClassLabel(names=["negative", "positive"]), } ), supervised_keys=("text", "label"), ) def _split_generators(self, dl_manager): print("generate") # breakpoints data_file = "data.json" return [ datasets.SplitGenerator( name=datasets.Split.TRAIN, gen_kwargs={"filepath": data_file} ), ] def _generate_examples(self, filepath): print("example") # breakpoints with open(filepath, encoding="utf-8") as f: data = json.load(f) for idx, sample in enumerate(data): yield idx, { "id": sample["id"], "text": sample["text"], "label": sample["label"], } #main.py import os os.environ["TRANSFORMERS_NO_MULTIPROCESSING"] = "1" from datasets import load_dataset dataset = load_dataset("my_dataset.py", split="train", cache_dir=None) print(dataset[:5]) ### Expected behavior Pause at breakpoints while running debugging ### Environment info pycharm

Adding column with dict struction when mapping lead to wrong order

### Describe the bug in `map()` function, I want to add a new column with a dict structure. ``` def map_fn(example): example['text'] = {'user': ..., 'assistant': ...} return example ``` However this leads to a wrong order `{'assistant':..., 'user':...}` in the dataset. Thus I can't concatenate two datasets due to the different feature structures. [Here](https://colab.research.google.com/drive/1zeaWq9Ith4DKWP_EiBNyLfc8S8I68LyY?usp=sharing) is a minimal reproducible example This seems an issue in low level pyarrow library instead of datasets, however, I think datasets should allow concatenate two datasets actually in the same structure. ### Steps to reproduce the bug [Here](https://colab.research.google.com/drive/1zeaWq9Ith4DKWP_EiBNyLfc8S8I68LyY?usp=sharing) is a minimal reproducible example ### Expected behavior two datasets could be concatenated. ### Environment info N/A

Feature Request: Add functionality to pass split types like train, test in DatasetDict.map

open

NONE

Hello datasets! We often encounter situations where we need to preprocess data differently depending on split types such as train, valid, and test. However, while DatasetDict.map has features to pass rank or index, there's no functionality to pass split types. Therefore, I propose adding a 'with_splits' parameter to DatasetDict, which would allow passing the split type through fn_kwargs.

"完成校正装置设计后需要进行哪些工作？" }, { "role": "assistant", "content": "一旦完成校正装置设计后，需要进行系统实际调校工作，或者进行MATLAB仿真以检查系统的时间响应特性。这时，需将系统建模时省略的部分尽可能加入系统，以保证仿真结果的逼真度。如果由于系统各种固有非线性因素影响，或者由于系统噪声和负载效应等因素的影响，使已校正系统不能满足全部性能指标要求，则需要适当调整校正装置的形式或参数，直到已校正系统满足全部性能指标为止。" } ] } { "messages": [ { "role": "user", "content": "为什么闭环带宽要求会影响串联超前校正的效果？" }, { "role": "assistant", "content": "如果待校正系统不稳定，为了满足相角裕度的要求，超前网络需要提供很大的相角超前量。这会导致超前网络的a值必须选得很大，从而使已校正系统的带宽过大。带宽过大会使通过系统的高频噪声电平变高，可能导致系统失控。因此，闭环带宽的要求会影响串联超前校正的效果。" } ] } 2. 当我把倒数第二个数据集再次添加到数据集中时，此时我的最后三个数据集是 { "messages": [ { "role":

(wip and experimental) adding the `Video` type based on `VideoReader` from `decord` ```python >>>from datasets import load_dataset >>> ds = load_dataset("path/to/videos", split="train").with_format("torch") >>> print(ds[0]["video"]) <decord.video_reader.VideoReader object at 0x337a47910> >>> print(ds[0]["video"][0]) tensor([[[73, 73, 73], [73, 73, 73], [73, 73, 73], ..., [23, 23, 23], [23, 23, 23], [23, 23, 23]]], dtype=torch.uint8) ``` the storage is the same as for audio and images: `{"path": pa.string(), "bytes": pa.binary()}` and I did a small to keep the hf:// URL in the "path" field if possible, this way the viewer can link to fiels on the hub if possible

Composite (multi-column) features

open

CONTRIBUTOR

### Feature request Structured data types (graphs etc.) might often be most efficiently stored as multiple columns, which then need to be combined during feature decoding Although it is currently possible to nest features as structs, my impression is that in particular when dealing with e.g. a feature composed of multiple numpy array / ArrayXD's, it would be more efficient to store each ArrayXD as a separate column (though I'm not sure by how much) Perhaps specification / implementation could be supported by something like: ``` features=Features(**{("feature0", "feature1")=Features(feature0=Array2D((None,10), dtype="float32"), feature1=Array2D((None,10), dtype="float32")) ``` ### Motivation Defining efficient composite feature types based on numpy arrays for representing data such as graphs with multiple node and edge attributes is currently challenging. ### Your contribution Possibly able to contribute

fast array extraction

CONTRIBUTOR

Implements #7210 using method suggested in https://github.com/huggingface/datasets/pull/7207#issuecomment-2411789307 ```python import numpy as np from datasets import Dataset, Features, Array3D features=Features(**{"array0": Array3D((None, 10, 10), dtype="float32"), "array1": Array3D((None,10,10), dtype="float32")}) dataset = Dataset.from_dict({f"array{i}": [np.zeros((x,10,10), dtype=np.float32) for x in [2000,1000]*25] for i in range(2)}, features=features) ``` ~0.02 s vs 0.9s on main ```python ds = dataset.to_iterable_dataset() t0 = time.time() for ex in ds: pass t1 = time.time() ``` < 0.01 s vs 1.3 s on main @lhoestq I can see this breaks a bunch of array-related tests but can update the test cases if you would support making this change? I also added an Array1D feature which will always be decoded into a numpy array and likewise improves extraction performance: ```python from datasets import Dataset, Features, Array1D, Sequence, Value array_features=Features(**{"array0": Array1D((None,), dtype="float32"), "array1": Array1D((None,), dtype="float32")}) sequence_features=Features(**{"array0": Sequence(feature=Value("float32"), length=-1), "array1": Sequence(feature=Value("float32"), length=-1)}) array_dataset = Dataset.from_dict({f"array{i}": [np.zeros((x,), dtype=np.float32) for x in [20000,10000]*25] for i in range(2)}, features=array_features) sequence_dataset = Dataset.from_dict({f"array{i}": [np.zeros((x,), dtype=np.float32) for x in [20000,10000]*25] for i in range(2)}, features=sequence_features) ```python t0 = time.time() for ex in array_dataset.to_iterable_dataset(): pass t1 = time.time() ``` < 0.01 s ```python t0 = time.time() for ex in sequence_dataset.to_iterable_dataset(): pass t1 = time.time() ``` ~1.1s And also added support for extracting structs of arrays as dicts of numpy arrays: ```python import numpy as np from datasets import Dataset, Features, Array3D, Sequence features=Features(struct={"array0": Array3D((None,10,10), dtype="float32"), "array1": Array3D((None,10,10), dtype="float32")}, _list=Sequence(feature=Array3D((None,10,10), dtype="float32"))) dataset = Dataset.from_dict({"struct": [{f"array{i}": np.zeros((x,10,10), dtype=np.float32) for i in range(2)} for x in [2000,1000]*25], "_list": [[np.zeros((x,10,10), dtype=np.float32) for i in range(2)] for x in [2000,1000]*25]}, features=features) ``` ```python t0 = time.time() for ex in dataset.to_iterable_dataset(): pass t1 = time.time() assert isinstance(ex["struct"]["array0"], np.ndarray) and ex["struct"]["array0"].ndim == 3 ``` ~0.02 s and no exception vs ~7s with an exception on main

Add R as a How to use from the Polars (R) Library as an option

open

NONE

### Feature request The boiler plate code to access a dataset via the hugging face file system is very useful. Please addd ## Add Polars (R) option The equivailent code works, because the [Polars-R](https://github.com/pola-rs/r-polars) wrapper has hugging faces funcitonaliy as well. ```r library(polars) df <- pl$read_parquet("hf://datasets/SALURBAL/core__admin_cube_public/core__admin_cube_public.parquet") ``` ## Polars (python) option  ## Libraries Currently  ### Motivation There are many data/analysis/research/statistics teams (particularly in academia and pharma) that use R as the default language. R has great integration with most of the newer data techs (arrow, parquet, polars) and having this included could really help in bringing this community into the hugging faces ecosystem. **This is a small/low-hanging-fruit front end change but would make a big impact expanding the community** ### Your contribution I am not sure which repositroy this should be in, but I have experience in R, Python and JS and happy to submit a PR in the appropriate repository.

Our git client jGit reports that the hf git server returns null as Content-Type after a push. ### Steps to reproduce the bug A basic kotlin application: ``` val person = PersonIdent( "padmalcom", "padmalcom@sth.com" ) val cp = UsernamePasswordCredentialsProvider( "padmalcom", "mysecrettoken" ) val git = KGit.cloneRepository { setURI("https://huggingface.co/datasets/sth/images") setTimeout(60) setProgressMonitor(TextProgressMonitor()) setCredentialsProvider(cp) } FileOutputStream("./images/images.csv").apply { writeCsv(images) } git.add { addFilepattern("images.csv") } for (i in images) { FileUtils.copyFile( File("./files/${i.id}"), File("./images/${i.id + File(i.fileName).extension }") ) git.add { addFilepattern("${i.id + File(i.fileName).extension }") } } val revCommit = git.commit { author = person message = "Uploading images at " + LocalDateTime.now() .format(DateTimeFormatter.ISO_DATE_TIME) setCredentialsProvider(cp) } val push = git.push { setCredentialsProvider(cp) } ``` ### Expected behavior The git server is expected to return the Content-Type _application/x-git-receive-pack-result_. ### Environment info It is independent from the datasets library.

fallback to default feature casting in case custom features not available during dataset loading

open

CONTRIBUTOR

a fix for #7223 in case datasets is happy to support this kind of extensibility! seems cool / powerful for allowing sharing of datasets with potentially different feature types

Fallback to arrow defaults when loading dataset with custom features that aren't registered locally

open

CONTRIBUTOR

### Describe the bug Datasets allows users to create and register custom features. However if datasets are then pushed to the hub, this means that anyone calling load_dataset without registering the custom Features in the same way as the dataset creator will get an error message. It would be nice to offer a fallback in this case. ### Steps to reproduce the bug ```python load_dataset("alex-hh/custom-features-example") ``` (Dataset creation process - must be run in separate session so that NewFeature isn't registered in session in which download is attempted:) ```python from dataclasses import dataclass, field import pyarrow as pa from datasets.features.features import register_feature from datasets import Dataset, Features, Value, load_dataset from datasets import Feature @dataclass class NewFeature(Feature): _type: str = field(default="NewFeature", init=False, repr=False) def __call__(self): return pa.int32() def examples_generator(): for i in range(5): yield {"feature": i} ds = Dataset.from_generator(examples_generator, features=Features(feature=NewFeature())) ds.push_to_hub("alex-hh/custom-features-example") register_feature(NewFeature, "NewFeature") ``` ### Expected behavior It would be nice, and offer greater extensibility, if there was some kind of graceful fallback mechanism in place for cases where user-defined features are stored in the dataset but not available locally. ### Environment info 3.0.2
