class SMALL100Tokenizer(PreTrainedTokenizer):
|
65 |
+
"""
|
66 |
+
Construct an SMALL100 tokenizer. Based on [SentencePiece](https://github.com/google/sentencepiece).
|
67 |
+
This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
|
68 |
+
this superclass for more information regarding those methods.
|
69 |
+
Args:
|
70 |
+
vocab_file (`str`):
|
71 |
+
Path to the vocabulary file.
|
72 |
+
spm_file (`str`):
|
73 |
+
Path to [SentencePiece](https://github.com/google/sentencepiece) file (generally has a .spm extension) that
|
74 |
+
contains the vocabulary.
|
75 |
+
tgt_lang (`str`, *optional*):
|
76 |
+
A string representing the target language.
|
77 |
+
eos_token (`str`, *optional*, defaults to `"</s>"`):
|
78 |
+
The end of sequence token.
|
79 |
+
sep_token (`str`, *optional*, defaults to `"</s>"`):
|
80 |
+
The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
|
81 |
+
sequence classification or for a text and a question for question answering. It is also used as the last
|
82 |
+
token of a sequence built with special tokens.
|
83 |
+
unk_token (`str`, *optional*, defaults to `"<unk>"`):
|
84 |
+
The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
|
85 |
+
token instead.
|
86 |
+
pad_token (`str`, *optional*, defaults to `"<pad>"`):
|
87 |
+
The token used for padding, for example when batching sequences of different lengths.
|
88 |
+
language_codes (`str`, *optional*):
|
89 |
+
What language codes to use. Should be `"m2m100"`.
|
90 |
+
sp_model_kwargs (`dict`, *optional*):
|
91 |
+
Will be passed to the `SentencePieceProcessor.__init__()` method. The [Python wrapper for
|
92 |
+
SentencePiece](https://github.com/google/sentencepiece/tree/master/python) can be used, among other things,
|
93 |
+
to set:
|
94 |
+
- `enable_sampling`: Enable subword regularization.
|
95 |
+
- `nbest_size`: Sampling parameters for unigram. Invalid for BPE-Dropout.
|
96 |
+
- `nbest_size = {0,1}`: No sampling is performed.
|
97 |
+
- `nbest_size > 1`: samples from the nbest_size results.
|
98 |
+
- `nbest_size < 0`: assuming that nbest_size is infinite and samples from the all hypothesis (lattice)
|
99 |
+
using forward-filtering-and-backward-sampling algorithm.
|
100 |
+
- `alpha`: Smoothing parameter for unigram sampling, and dropout probability of merge operations for
|
101 |
+
BPE-dropout.
|
102 |
+
Examples:
|
103 |
+
```python
|
104 |
+
>>> from tokenization_small100 import SMALL100Tokenizer
|
105 |
+
>>> tokenizer = SMALL100Tokenizer.from_pretrained("alirezamsh/small100", tgt_lang="ro")
|
106 |
+
>>> src_text = " UN Chief Says There Is No Military Solution in Syria"
|
107 |
+
>>> tgt_text = "Şeful ONU declară că nu există o soluţie militară în Siria"
|
108 |
+
>>> model_inputs = tokenizer(src_text, text_target=tgt_text, return_tensors="pt")
|
109 |
+
>>> model(**model_inputs) # should work
