🤗 hf-xet - xet client tech, used in huggingface_hub

Welcome

hf-xet enables huggingface_hub to utilize xet storage for uploading and downloading to HF Hub. Xet storage provides chunk-based deduplication, efficient storage/retrieval with local disk caching, and backwards compatibility with Git LFS. This library is not meant to be used directly, and is instead intended to be used from huggingface_hub.

Key features

♻ chunk-based deduplication implementation: avoid transferring and storing chunks that are shared across binary files (models, datasets, etc).

🤗 Python bindings: bindings for huggingface_hub package.

↔ network communications: concurrent communication to HF Hub Xet backend services (CAS).

🔖 local disk caching: chunk-based cache that sits alongside the existing huggingface_hub disk cache.

Installation

Install the hf_xet package with pip:

pip install hf_xet

Quick Start

hf_xet is not intended to be run independently as it is expected to be used from huggingface_hub, so to get started with huggingface_hub check out the documentation here.

Contributions (feature requests, bugs, etc.) are encouraged & appreciated 💙💚💛💜🧡❤️
