|
||||||

## Quickstart
|
||||||
|
```shell
|
||||||
|
#构建docker镜像
|
||||||
|
docker build . -t mlu370_translation
|
||||||
|
|
||||||
|
#运行docker容器
|
||||||
|
docker run -it -p 10078:80 --device=/dev/cambricon_dev0:/dev/cambricon_dev0 --device=/dev/cambricon_ctl --device=/dev/cambricon_ipcm0:/dev/cambricon_ipcm0 -e MODEL_TYPE=opus_mt -e MODEL_NAME=moxying/opus-mt-zh-en --name mlu370_translation_test mlu370_translation
|
||||||
|
```
|
||||||
|
等待模型下载完成,出现以下日志时,代表服务启动成功
|
||||||
|
```shell
|
||||||
|
INFO: Application startup complete.
|
||||||
|
INFO: Uvicorn running on http://0.0.0.0:80 (Press CTRL+C to quit)
|
||||||
|
```
|
||||||
|
执行测试程序
|
||||||
|
```shell
|
||||||
|
python3 test.py
|
||||||
|
```
|
||||||
|
测试程序执行结果
|
||||||
|
```
|
||||||
|
Succeed!
|
||||||
|
Response: [{'translations': [{'origin_text': '生活就像一块巧克力', 'translated': 'Life is like a piece of chocolate.'}, {'origin_text': '你来自哪里', 'translated': 'Where are you from?'}, {'origin_text': '你吃饭了吗', 'translated': 'Have you eaten yet?'}]}]
|
||||||
|
```
|
||||||
|
停止docker容器
|
||||||
|
```
|
||||||
|
docker stop mlu370_translation_test
|
||||||
|
```
|
||||||
|
## 模型支持
|
||||||
|
在Quickstart中运行容器时,通过环境变量的方式,指定模型的类型和具体的模型名称,即:
|
||||||
|
```
|
||||||
|
-e MODEL_TYPE=opus_mt -e MODEL_NAME=moxying/opus-mt-zh-en
|
||||||
|
```
|
||||||
|
目前支持以下几种配置:
|
||||||
|
| MODEL_TYPE | MODEL_NAME |
|
||||||
|
| ---------- | --------------------------------------- |
|
||||||
|
| nllb200 | facebook/nllb-200-distilled-600M |
|
||||||
|
| small100 | aiyueqi/alirezamsh_small100 |
|
||||||
|
| mbart | facebook/mbart-large-50-many-to-many-mmt|
|
||||||
|
| opus_mt | moxying/opus-mt-zh-en |
|
||||||
|
|
||||||
|
其中,MODEL_TYPE代表模型类型,必须为以上表格列举之一;MODEL_NAME是modelscope上面能够拉取到的模型名称,需要和MODEL_TYPE对应

class SMALL100Tokenizer(PreTrainedTokenizer):

|
"""
|
||||||
|
Construct an SMALL100 tokenizer. Based on [SentencePiece](https://github.com/google/sentencepiece).
|
||||||
|
This tokenizer inherits from [`PreTrainedTokenizer`] which contains most of the main methods. Users should refer to
|
||||||
|
this superclass for more information regarding those methods.
|
||||||
|
Args:
|
||||||
|
vocab_file (`str`):
|
||||||
|
Path to the vocabulary file.
|
||||||
|
spm_file (`str`):
|
||||||
|
Path to [SentencePiece](https://github.com/google/sentencepiece) file (generally has a .spm extension) that
|
||||||
|
contains the vocabulary.
|
||||||
|
tgt_lang (`str`, *optional*):
|
||||||
|
A string representing the target language.
|
||||||
|
eos_token (`str`, *optional*, defaults to `"</s>"`):
|
||||||
|
The end of sequence token.
|
||||||
|
sep_token (`str`, *optional*, defaults to `"</s>"`):
|
||||||
|
The separator token, which is used when building a sequence from multiple sequences, e.g. two sequences for
|
||||||
|
sequence classification or for a text and a question for question answering. It is also used as the last
|
||||||
|
token of a sequence built with special tokens.
|
||||||
|
unk_token (`str`, *optional*, defaults to `"<unk>"`):
|
||||||
|
The unknown token. A token that is not in the vocabulary cannot be converted to an ID and is set to be this
|
||||||
|
token instead.
|
||||||
|
pad_token (`str`, *optional*, defaults to `"<pad>"`):
|
||||||
|
The token used for padding, for example when batching sequences of different lengths.
|
||||||
|
language_codes (`str`, *optional*):
|
||||||
|
What language codes to use. Should be `"m2m100"`.
|
||||||
|
sp_model_kwargs (`dict`, *optional*):
|
||||||
|
Will be passed to the `SentencePieceProcessor.__init__()` method. The [Python wrapper for
|
||||||
|
SentencePiece](https://github.com/google/sentencepiece/tree/master/python) can be used, among other things,
|
||||||
|
to set:
|
||||||
|
- `enable_sampling`: Enable subword regularization.
|
||||||
|
- `nbest_size`: Sampling parameters for unigram. Invalid for BPE-Dropout.
|
||||||
|
- `nbest_size = {0,1}`: No sampling is performed.
|
||||||
|
- `nbest_size > 1`: samples from the nbest_size results.
|
||||||
|
- `nbest_size < 0`: assuming that nbest_size is infinite and samples from the all hypothesis (lattice)
|
||||||
|
using forward-filtering-and-backward-sampling algorithm.
|
||||||
|
- `alpha`: Smoothing parameter for unigram sampling, and dropout probability of merge operations for
|
||||||
|
BPE-dropout.
|
||||||
|
Examples:
|
||||||
|
```python
|
||||||
|
>>> from tokenization_small100 import SMALL100Tokenizer
|
||||||
|
>>> tokenizer = SMALL100Tokenizer.from_pretrained("alirezamsh/small100", tgt_lang="ro")

|
>>> src_text = " UN Chief Says There Is No Military Solution in Syria"
|
||||||
|
>>> tgt_text = "Şeful ONU declară că nu există o soluţie militară în Siria"
