xet-data
experimentalv1.5.2
Data processing pipeline for chunking, deduplication, and file reconstruction; used in the Hugging Face Xet client tools. Intended to be used through the API in the hf-xet package.
67
safetensors
growingv0.7.0
Provides functions to read and write safetensors which aim to be safer than their PyTorch counterpart. The format is 8 bytes which is an unsized int, being the size of a JSON header, the JSON header refers the `dtype` the `shape` and `data_offsets` which are the offsets for the values in the rest of the file.
64
tokenizers
growingv0.23.1
Provides an implementation of today's most used tokenizers, with a focus on performances and versatility.
