"""
|
| 44 |
+
Adapted from [`RobertaTokenizer`] and [`XLNetTokenizer`]. Construct a CamemBERT tokenizer. Based on
|
| 45 |
+
[SentencePiece](https://github.com/google/sentencepiece).
|
| 46 |
+
|
| 47 |
+
This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
|
| 48 |
+
this superclass for more information regarding those methods.
|
| 49 |
+
|
| 50 |
+
Args:
|
| 51 |
+
vocab_file (`str`):
|
| 52 |
+
[SentencePiece](https://github.com/google/sentencepiece) file (generally has a *.spm* extension) that
|
| 53 |
+
contains the vocabulary necessary to instantiate a tokenizer.
|
| 54 |
+
bos_token (`str`, *optional*, defaults to `"<cls>"`):
|
| 55 |
+
The beginning of sequence token that was used during pretraining. Can be used a sequence classifier token.
|
| 56 |
+
|
| 57 |
+
<Tip>
|
| 58 |
+
|
| 59 |
+
When building a sequence using special tokens, this is not the token that is used for the beginning of
|
| 60 |
+
sequence. The token used is the `cls_token`.
|
| 61 |
+
|
| 62 |
+
</Tip>
|
| 63 |
+
|
| 64 |
+
eos_token (`str`, *optional*, defaults to `"<sep>"`):
|
| 65 |
+
The end of sequence token.
|
| 66 |
+
|
| 67 |
+
<Tip>
|
| 68 |
+
|
| 69 |
+
When building a sequence using special tokens, this is not the token that is used for the end of sequence.
|
| 70 |
+
The token used is the `sep_token`.
|
| 71 |
+
|
| 72 |
+
</Tip>
|
| 73 |
+
|
| 74 |
+
sep_token (`str`, *optional*, defaults to `"<sep>"`):
|
| 75 |
+
The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
|
| 76 |
+
sequence classification or for a text and a question for question answering. It is also used as the last
|
| 77 |
+
token of a sequence built with special tokens.
|
| 78 |
+
cls_token (`str`, *optional*, defaults to `"<cls>"`):
|
| 79 |
+
The classifier token which is used when doing sequence classification (classification of the whole sequence
|
| 80 |
+
instead of per-token classification). It is the first token of the sequence when built with special tokens.
|
| 81 |
+
unk_token (`str`, *optional*, defaults to `"<unk>"`):
|
| 82 |
+
The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
|
| 83 |
+
token instead.
|
| 84 |
+
pad_token (`str`, *optional*, defaults to `"<pad>"`):
|
| 85 |
+
The token used for padding, for example when batching sequences of different lengths.
|
| 86 |
+
mask_token (`str`, *optional*, defaults to `"<mask>"`):
|
| 87 |
+
The token used for masking values. This is the token used when training this model with masked language
|
| 88 |
+
modeling. This is the token which the model will try to predict.
|
| 89 |
+
sp_model_kwargs (`dict`, *optional*):
|
| 90 |
+
Will be passed to the `SentencePieceProcessor.__init__()` method. The [Python wrapper for
|
| 91 |
+
SentencePiece](https://github.com/google/sentencepiece/tree/master/python) can be used, among other things,
|
| 92 |
+
to set:
|
| 93 |
+
|
| 94 |
+
- `enable_sampling`: Enable subword regularization.
|
| 95 |
+
- `nbest_size`: Sampling parameters for unigram. Invalid for BPE-Dropout.
|
| 96 |
+
|
| 97 |
+
- `nbest_size = {0,1}`: No sampling is performed.
|
| 98 |
+
- `nbest_size > 1`: samples from the nbest_size results.
|
| 99 |
+
- `nbest_size < 0`: assuming that nbest_size is infinite and samples from the all hypothesis (lattice)
|
| 100 |
+
using forward-filtering-and-backward-sampling algorithm.
|
| 101 |
+
|
| 102 |
+
- `alpha`: Smoothing parameter for unigram sampling, and dropout probability of merge operations for
|
| 103 |
+
BPE-dropout.
|
| 104 |
+
|
| 105 |
+
Attributes:
|
| 106 |
+
sp_model (`SentencePieceProcessor`):
|
| 107 |
+
The *SentencePiece* processor that is used for every conversion (string, tokens and IDs).
