README:
🤗 Datasets is a lightweight library providing two main features:
-
one-line dataloaders for many public datasets: one-liners to download and pre-process any of the
major public datasets (image datasets, audio datasets, text datasets in 467 languages and dialects, etc.) provided on the HuggingFace Datasets Hub. With a simple command like
squad_dataset = load_dataset("rajpurkar/squad"), get any of these datasets ready to use in a dataloader for training/evaluating a ML model (Numpy/Pandas/PyTorch/TensorFlow/JAX), -
efficient data pre-processing: simple, fast and reproducible data pre-processing for the public datasets as well as your own local datasets in CSV, JSON, text, PNG, JPEG, WAV, MP3, Parquet, HDF5, etc. With simple commands like
processed_dataset = dataset.map(process_example), efficiently prepare the dataset for inspection and ML model evaluation and training.
🎓 Documentation 🔎 Find a dataset in the Hub 🌟 Share a dataset on the Hub
🤗 Datasets is designed to let the community easily add and share new datasets.
🤗 Datasets has many additional interesting features:
- Thrive on large datasets: 🤗 Datasets naturally frees the user from RAM memory limitation, all datasets are memory-mapped using an efficient zero-serialization cost backend (Apache Arrow).
- Smart caching: never wait for your data to process several times.
- Lightweight and fast with a transparent and pythonic API (multi-processing/caching/memory-mapping).
- Built-in interoperability with NumPy, PyTorch, TensorFlow 2, JAX, Pandas, Polars and more.
- Native support for audio, image and video data.
- Enable streaming mode to save disk space and start iterating over the dataset immediately.
🤗 Datasets originated from a fork of the awesome TensorFlow Datasets and the HuggingFace team want to deeply thank the TensorFlow Datasets team for building this amazing library.
🤗 Datasets can be installed from PyPi and has to be installed in a virtual environment (venv or conda for instance)
pip install datasets🤗 Datasets can be installed using conda as follows:
conda install -c huggingface -c conda-forge datasetsFollow the installation pages of TensorFlow and PyTorch to see how to install them with conda.
For more details on installation, check the installation page in the documentation: https://huggingface.co/docs/datasets/installation
If you plan to use 🤗 Datasets with PyTorch (2.0+), TensorFlow (2.6+) or JAX (3.14+) you should also install PyTorch, TensorFlow or JAX. 🤗 Datasets is also well integrated with data frameworks like PyArrow, Pandas, Polars and Spark, which should be installed separately.
For more details on using the library with these frameworks, check the quick start page in the documentation: https://huggingface.co/docs/datasets/quickstart
🤗 Datasets is made to be very simple to use - the API is centered around a single function, datasets.load_dataset(dataset_name, **kwargs), that instantiates a dataset.
This library can be used for text/image/audio/etc. datasets. Here is an example to load a text dataset:
Here is a quick example:
from datasets import load_dataset
# Print all the available datasets
from huggingface_hub import list_datasets
print([dataset.id for dataset in list_datasets()])
# Load a dataset and print the first example in the training set
squad_dataset = load_dataset('rajpurkar/squad')
print(squad_dataset['train'][0])
# Process the dataset - add a column with the length of the context texts
dataset_with_length = squad_dataset.map(lambda x: {"length": len(x["context"])})
# Process the dataset - tokenize the context texts (using a tokenizer from the 🤗 Transformers library)
from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained('bert-base-cased')
tokenized_dataset = squad_dataset.map(lambda x: tokenizer(x['context']), batched=True)If your dataset is bigger than your disk or if you don't want to wait to download the data, you can use streaming:
# If you want to use the dataset immediately and efficiently stream the data as you iterate over the dataset
image_dataset = load_dataset('timm/imagenet-1k-wds', streaming=True)
for example in image_dataset["train"]:
