	<span>Tokenizer
	</span></h1>

<p>A tokenizer is in charge of preparing the inputs for a model. The library contains tokenizers for all the models. Most
of the tokenizers are available in two flavors: a full python implementation and a “Fast” implementation based on the
Rust library <a href="https://github.com/huggingface/tokenizers" rel="nofollow">🤗 Tokenizers</a>. The “Fast” implementations allows:</p>
<ol><li>a significant speed-up in particular when doing batched tokenization and</li>
<li>additional methods to map between the original string (character and words) and the token space (e.g. getting the
index of the token comprising a given character or the span of characters corresponding to a given token). </li></ol>
<p>The base classes <a href="/docs/transformers/pr_17548/en/main_classes/tokenizer#transformers.PreTrainedTokenizer">PreTrainedTokenizer</a> and <a href="/docs/transformers/pr_17548/en/main_classes/tokenizer#transformers.PreTrainedTokenizerFast">PreTrainedTokenizerFast</a>
implement the common methods for encoding string inputs in model inputs (see below) and instantiating/saving python and
“Fast” tokenizers either from a local file or directory or from a pretrained tokenizer provided by the library
(downloaded from HuggingFace’s AWS S3 repository). They both rely on
<a href="/docs/transformers/pr_17548/en/internal/tokenization_utils#transformers.PreTrainedTokenizerBase">PreTrainedTokenizerBase</a> that contains the common methods, and
<a href="/docs/transformers/pr_17548/en/internal/tokenization_utils#transformers.SpecialTokensMixin">SpecialTokensMixin</a>.</p>
<p><a href="/docs/transformers/pr_17548/en/main_classes/tokenizer#transformers.PreTrainedTokenizer">PreTrainedTokenizer</a> and <a href="/docs/transformers/pr_17548/en/main_classes/tokenizer#transformers.PreTrainedTokenizerFast">PreTrainedTokenizerFast</a> thus implement the main
methods for using all the tokenizers:</p>
<ul><li>Tokenizing (splitting strings in sub-word token strings), converting tokens strings to ids and back, and
encoding/decoding (i.e., tokenizing and converting to integers).</li>
<li>Adding new tokens to the vocabulary in a way that is independent of the underlying structure (BPE, SentencePiece…).</li>
<li>Managing special tokens (like mask, beginning-of-sentence, etc.): adding them, assigning them to attributes in the
tokenizer for easy access and making sure they are not split during tokenization.</li></ul>
<p><a href="/docs/transformers/pr_17548/en/main_classes/tokenizer#transformers.BatchEncoding">BatchEncoding</a> holds the output of the
<a href="/docs/transformers/pr_17548/en/internal/tokenization_utils#transformers.PreTrainedTokenizerBase">PreTrainedTokenizerBase</a>’s encoding methods (<code>__call__</code>,
<code>encode_plus</code> and <code>batch_encode_plus</code>) and is derived from a Python dictionary. When the tokenizer is a pure python
tokenizer, this class behaves just like a standard python dictionary and holds the various model inputs computed by
these methods (<code>input_ids</code>, <code>attention_mask</code>…). When the tokenizer is a “Fast” tokenizer (i.e., backed by
HuggingFace <a href="https://github.com/huggingface/tokenizers" rel="nofollow">tokenizers library</a>), this class provides in addition
several advanced alignment methods which can be used to map between the original string (character and words) and the
token space (e.g., getting the index of the token comprising a given character or the span of characters corresponding
to a given token).</p>

<p>Base class for all slow tokenizers.</p>
<p>Inherits from <a href="/docs/transformers/pr_17548/en/internal/tokenization_utils#transformers.PreTrainedTokenizerBase">PreTrainedTokenizerBase</a>.</p>
<p>Handle all the shared methods for tokenization and special tokens as well as methods downloading/caching/loading
pretrained tokenizers as well as adding tokens to the vocabulary.</p>
<p>This class also contain the added tokens in a unified way on top of all tokenizers so we don’t have to handle the
specific vocabulary augmentation methods of the various underlying dictionary structures (BPE, sentencepiece…).</p>
<p>Class attributes (overridden by derived classes)</p>
<ul><li><strong>vocab_files_names</strong> (<code>Dict[str, str]</code>) — A dictionary with, as keys, the <code>__init__</code> keyword name of each
vocabulary file required by the model, and as associated values, the filename for saving the associated file
(string).</li>
<li><strong>pretrained_vocab_files_map</strong> (<code>Dict[str, Dict[str, str]]</code>) — A dictionary of dictionaries, with the
high-level keys being the <code>__init__</code> keyword name of each vocabulary file required by the model, the
low-level being the <code>short-cut-names</code> of the pretrained models with, as associated values, the <code>url</code> to the
associated pretrained vocabulary file.</li>
<li><strong>max_model_input_sizes</strong> (<code>Dict[str, Optional[int]]</code>) — A dictionary with, as keys, the <code>short-cut-names</code>
of the pretrained models, and as associated values, the maximum length of the sequence inputs of this model,
or <code>None</code> if the model has no maximum input size.</li>
<li><strong>pretrained_init_configuration</strong> (<code>Dict[str, Dict[str, Any]]</code>) — A dictionary with, as keys, the
<code>short-cut-names</code> of the pretrained models, and as associated values, a dictionary of specific arguments to
pass to the <code>__init__</code> method of the tokenizer class for this pretrained model when loading the tokenizer
with the <a href="/docs/transformers/pr_17548/en/internal/tokenization_utils#transformers.PreTrainedTokenizerBase.from_pretrained">from_pretrained()</a> method.</li>
<li><strong>model_input_names</strong> (<code>List[str]</code>) — A list of inputs expected in the forward pass of the model.</li>
<li><strong>padding_side</strong> (<code>str</code>) — The default value for the side on which the model should have padding applied.
Should be <code>&#39;right&#39;</code> or <code>&#39;left&#39;</code>.</li>

<p>Base class for all fast tokenizers (wrapping HuggingFace tokenizers library).</p>
<p>Inherits from <a href="/docs/transformers/pr_17548/en/internal/tokenization_utils#transformers.PreTrainedTokenizerBase">PreTrainedTokenizerBase</a>.</p>
<p>Handles all the shared methods for tokenization and special tokens, as well as methods for
downloading/caching/loading pretrained tokenizers, as well as adding tokens to the vocabulary.</p>
<p>This class also contains the added tokens in a unified way on top of all tokenizers so we don’t have to handle the
specific vocabulary augmentation methods of the various underlying dictionary structures (BPE, sentencepiece…).</p>
<p>Class attributes (overridden by derived classes)</p>
<ul><li><strong>vocab_files_names</strong> (<code>Dict[str, str]</code>) — A dictionary with, as keys, the <code>__init__</code> keyword name of each
vocabulary file required by the model, and as associated values, the filename for saving the associated file
(string).</li>
<li><strong>pretrained_vocab_files_map</strong> (<code>Dict[str, Dict[str, str]]</code>) — A dictionary of dictionaries, with the
high-level keys being the <code>__init__</code> keyword name of each vocabulary file required by the model, the
low-level being the <code>short-cut-names</code> of the pretrained models with, as associated values, the <code>url</code> to the
associated pretrained vocabulary file.</li>
<li><strong>max_model_input_sizes</strong> (<code>Dict[str, Optional[int]]</code>) — A dictionary with, as keys, the <code>short-cut-names</code>
of the pretrained models, and as associated values, the maximum length of the sequence inputs of this model,
or <code>None</code> if the model has no maximum input size.</li>
<li><strong>pretrained_init_configuration</strong> (<code>Dict[str, Dict[str, Any]]</code>) — A dictionary with, as keys, the
<code>short-cut-names</code> of the pretrained models, and as associated values, a dictionary of specific arguments to
pass to the <code>__init__</code> method of the tokenizer class for this pretrained model when loading the tokenizer
with the <a href="/docs/transformers/pr_17548/en/internal/tokenization_utils#transformers.PreTrainedTokenizerBase.from_pretrained">from_pretrained()</a> method.</li>
<li><strong>model_input_names</strong> (<code>List[str]</code>) — A list of inputs expected in the forward pass of the model.</li>
<li><strong>padding_side</strong> (<code>str</code>) — The default value for the side on which the model should have padding applied.
Should be <code>&#39;right&#39;</code> or <code>&#39;left&#39;</code>.</li>
<li><strong>truncation_side</strong> (<code>str</code>) — The default value for the side on which the model should have truncation
applied. Should be <code>&#39;right&#39;</code> or <code>&#39;left&#39;</code>.</li></ul>

<p>Get the encoded token span corresponding to a word in a sequence of the batch.</p>
<p>Token spans are returned as a <a href="/docs/transformers/pr_17548/en/internal/tokenization_utils#transformers.TokenSpan">TokenSpan</a> with:</p>
<ul><li><strong>start</strong> — Index of the first token.</li>
<li><strong>end</strong> — Index of the token following the last token.</li></ul>
<p>Can be called as:</p>
<ul><li><code>self.word_to_tokens(word_index, sequence_index: int = 0)</code> if batch size is 1</li>
<li><code>self.word_to_tokens(batch_index, word_index, sequence_index: int = 0)</code> if batch size is greater or equal to
1</li></ul>
<p>This method is particularly suited when the input sequences are provided as pre-tokenized sequences (i.e. words
are defined by the user). In this case it allows to easily associate encoded tokens with provided tokenized
words.</p></div>
