Install dependencies with `uv` in CI

closed

COLLABORATOR

`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)

Dataset.to_csv() missing commas in columns with lists

open

NONE

### 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 ...

### Describe the bug I am trying to fine-tune llama2-7b model in GCP. 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)).  I see the files are being read correctly from the logs:  ### Steps to reproduce the bug 1. Clone the [vertex-ai-samples](https://github.com/GoogleCloudPlatform/vertex-ai-samples) repository. 2. Run the [llama2-7b peft fine-tuning](https://github.com/GoogleCloudPlatform/vertex-ai-samples/blob/main/notebooks/community/model_garden/model_garden_pytorch_llama2_peft_finetuning.ipynb). 3. Change the dataset `kk2491/finetune_dataset_002` ### Expected behavior The training should complete successfully, and model gets deployed to an endpoint. ### Environment info Python version : Python 3.10.12 Dataset : https://huggingface.co/datasets/kk2491/finetune_dataset_002

Generating split is very slow when Image format is PNG

open

NONE

### Describe the bug When I create a dataset, it gets stuck while generating cached data. The image format is PNG, and it will not get stuck when the image format is jpeg.  After debugging, I know that it is because of the `pa.array` operation in [arrow_writer](https://github.com/huggingface/datasets/blob/2.13.0/src/datasets/arrow_writer.py#L553), but i don't why. ### Steps to reproduce the bug ``` from datasets import Dataset def generator(lines): for line in lines: img = Image.open(open(line["url"], "rb")) # print(img.format) # "PNG" yield { "image": img, } lines = open(dataset_path, "r") dataset = Dataset.from_generator( generator, gen_kwargs={"lines": lines} ) ``` ### Expected behavior Generating split done. ### Environment info datasets 2.13.0

Dataset on Hub re-downloads every time?

closed

NONE

### 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

### 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. Then one will get the following error message: ``` Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/opt/conda/lib/python3.10/site-packages/datasets/load.py", line 2556, in load_dataset builder_instance = load_dataset_builder( File "/opt/conda/lib/python3.10/site-packages/datasets/load.py", line 2265, in load_dataset_builder builder_instance: DatasetBuilder = builder_cls( File "/opt/conda/lib/python3.10/site-packages/datasets/builder.py", line 371, in __init__ self.config, self.config_id = self._create_builder_config( File "/opt/conda/lib/python3.10/site-packages/datasets/builder.py", line 620, in _create_builder_config builder_config._resolve_data_files( File "/opt/conda/lib/python3.10/site-packages/datasets/builder.py", line 211, in _resolve_data_files self.data_files = self.data_files.resolve(base_path, download_config) File "/opt/conda/lib/python3.10/site-packages/datasets/data_files.py", line 799, in resolve out[key] = data_files_patterns_list.resolve(base_path, download_config) File "/opt/conda/lib/python3.10/site-packages/datasets/data_files.py", line 752, in resolve resolve_pattern( File "/opt/conda/lib/python3.10/site-packages/datasets/data_files.py", line 393, in resolve_pattern raise FileNotFoundError(error_msg) FileNotFoundError: Unable to find 'hf://datasets/trec@65752bf53af25bc935a0dce92fb5b6c930728450/default/train/0000.parquet' with any supported extension ['.csv', '.tsv', '.json', '.jsonl', '.parquet', '.geoparquet', '.gpq', '.arrow', '.txt', '.tar', '.blp', '.bmp', '.dib', '.bufr', '.cur', '.pcx', '.dcx', '.dds', '.ps', '.eps', '.fit', '.fits', '.fli', '.flc', '.ftc', '.ftu', '.gbr', '.gif', '.grib', '.h5', '.hdf', '.png', '.apng', '.jp2', '.j2k', '.jpc', '.jpf', '.jpx', '.j2c', '.icns', '.ico', '.im', '.iim', '.tif', '.tiff', '.jfif', '.jpe', '.jpg', '.jpeg', '.mpg', '.mpeg', '.msp', '.pcd', '.pxr', '.pbm', '.pgm', '.ppm', '.pnm', '.psd', '.bw', '.rgb', '.rgba', '.sgi', '.ras', '.tga', '.icb', '.vda', '.vst', '.webp', '.wmf', '.emf', '.xbm', '.xpm', '.BLP', '.BMP', '.DIB', '.BUFR', '.CUR', '.PCX', '.DCX', '.DDS', '.PS', '.EPS', '.FIT', '.FITS', '.FLI', '.FLC', '.FTC', '.FTU', '.GBR', '.GIF', '.GRIB', '.H5', '.HDF', '.PNG', '.APNG', '.JP2', '.J2K', '.JPC', '.JPF', '.JPX', '.J2C', '.ICNS', '.ICO', '.IM', '.IIM', '.TIF', '.TIFF', '.JFIF', '.JPE', '.JPG', '.JPEG', '.MPG', '.MPEG', '.MSP', '.PCD', '.PXR', '.PBM', '.PGM', '.PPM', '.PNM', '.PSD', '.BW', '.RGB', '.RGBA', '.SGI', '.RAS', '.TGA', '.ICB', '.VDA', '.VST', '.WEBP', '.WMF', '.EMF', '.XBM', '.XPM', '.aiff', '.au', '.avr', '.caf', '.flac', '.htk', '.svx', '.mat4', '.mat5', '.mpc2k', '.ogg', '.paf', '.pvf', '.raw', '.rf64', '.sd2', '.sds', '.ircam', '.voc', '.w64', '.wav', '.nist', '.wavex', '.wve', '.xi', '.mp3', '.opus', '.AIFF', '.AU', '.AVR', '.CAF', '.FLAC', '.HTK', '.SVX', '.MAT4', '.MAT5', '.MPC2K', '.OGG', '.PAF', '.PVF', '.RAW', '.RF64', '.SD2', '.SDS', '.IRCAM', '.VOC', '.W64', '.WAV', '.NIST', '.WAVEX', '.WVE', '.XI', '.MP3', '.OPUS', '.zip'] ``` 4.

CONTRIBUTOR

### 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!

Compatibility issue between s3fs, fsspec, and datasets

closed

NONE

### 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.

load_dataset can't work with symbolic links

open

NONE

### 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.

Fix issue with case sensitivity when loading dataset from local cache

open

NONE

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.

Allow polars as valid output type

CONTRIBUTOR

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.

Remove deprecated code

closed

CONTRIBUTOR

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.

Persistent multi-process Pool

open

NONE

### 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

closed

NONE

### 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

CONTRIBUTOR

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?

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

Option to disable file locking

open

NONE

### 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

closed

NONE

### 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.

Dict feature is non-nullable while nested dict feature is

closed

CONTRIBUTOR

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?

Mosaic Streaming (MDS) Support

open

NONE

### 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

EmptyDatasetError when loading dataset downloaded with HuggingFace cli

open

NONE

### 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

Deprecate Pandas builder

closed

COLLABORATOR

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.

Issue Downloading Certain Datasets After Setting Custom `HF_ENDPOINT`

closed

NONE

### 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

Using a registry instead of calling globals for fetching feature types

closed

CONTRIBUTOR

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'})}

Profiling for HF Filesystem shows there are easy performance gains to be made

open

NONE

### Describe the bug # Let's make it faster First, an evidence...  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:  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.

### 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

open

CONTRIBUTOR

### 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

Is there any way to solve hanging of IterableDataset using split by node + filtering during inference

open

NONE

### 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

Fix sliced ConcatenationTable pickling with mixed schemas vertically

closed

MEMBER

A sliced + pickled ConcatenationTable could end up with a different schema than the original schema, if the slice only contains blocks with only a subset of the columns. This can lead to issues when saving datasets from a concatenation of datasets with mixed schemas Reported in https://discuss.huggingface.co/t/datasetdict-save-to-disk-with-num-proc-1-seems-to-hang-with-error/75595

3x Faster Text Preprocessing

open

NONE

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?
