====================================================================================================
Fast State-of-the-art tokenizers, optimized for both research and production
`🤗 Tokenizers`_ provides an implementation of today's most used tokenizers, with
a focus on performance and versatility. These tokenizers are also used in
`🤗 Transformers`_.
.. _🤗 Tokenizers: https://github.com/huggingface/tokenizers
.. _🤗 Transformers: https://github.com/huggingface/transformers
Main features:
----------------------------------------------------------------------------------------------------
- Train new vocabularies and tokenize, using today's most used tokenizers.
- Extremely fast (both training and tokenization), thanks to the Rust implementation. Takes
less than 20 seconds to tokenize a GB of text on a server's CPU.
- Easy to use, but also extremely versatile.
- Designed for both research and production.
- Full alignment tracking. Even with destructive normalization, it's always possible to get
the part of the original sentence that corresponds to any token.
- Does all the pre-processing: Truncation, Padding, add the special tokens your model needs.
