Utilities for Tokenizers

This page lists all the utility functions used by the tokenizers, mainly the class [~tokenization_utils_base.PreTrainedTokenizerBase] that implements the common methods between [PreTrainedTokenizer] and [PreTrainedTokenizerFast] and the mixin [~tokenization_utils_base.SpecialTokensMixin].

Most of those are only useful if you are studying the code of the tokenizers in the library.
