HuggingFace tokenizers library), this class provides in addition When the tokenizer is a “Fast” tokenizer (i.e., backed by These methods ( input_ids, attention_mask…). Tokenizer, this class behaves just like a standard python dictionary and holds the various model inputs computed by PreTrainedTokenizerBase’s encoding methods ( _call_,Įncode_plus and batch_encode_plus) and is derived from a Python dictionary. Tokenizer for easy access and making sure they are not split during tokenization.

Managing special tokens (like mask, beginning-of-sentence, etc.): adding them, assigning them to attributes in the.

Adding new tokens to the vocabulary in a way that is independent of the underlying structure (BPE, SentencePiece…).

Tokenizing (splitting strings in sub-word token strings), converting tokens strings to ids and back, andĮncoding/decoding (i.e., tokenizing and converting to integers).

PreTrainedTokenizer and PreTrainedTokenizerFast thus implement the main

PreTrainedTokenizerBase that contains the common methods, and (downloaded from HuggingFace’s AWS S3 repository). “Fast” tokenizers either from a local file or directory or from a pretrained tokenizer provided by the library Implement the common methods for encoding string inputs in model inputs (see below) and instantiating/saving python and The base classes PreTrainedTokenizer and PreTrainedTokenizerFast Index of the token comprising a given character or the span of characters corresponding to a given token). additional methods to map between the original string (character and words) and the token space (e.g.a significant speed-up in particular when doing batched tokenization and.

Of the tokenizers are available in two flavors: a full python implementation and a “Fast” implementation based on the The library contains tokenizers for all the models. A tokenizer is in charge of preparing the inputs for a model.
