# colab notebook, no environment needed
简单的gpu colab笔记本，可以测试，不需要线下的环境配置和安装 <br>
总之换成gpu模式可以用啦，翻译一本小说什么的可读性不高（尴尬）<br>

# Release Notes
* this model is finetuned from mt5-base, training methods and datasets refers to larryvrh/mt5-translation-ja_zh
* used a trimmed and fused dataset CCMatrix-v1-Ja_Zh 1e-4 for 1 epoch no weight decay，arraived at about 1.5 val loss, pretty decent for this behemoth tokenizer
* spent about 26h on a modified 2080ti 22g graphic card, but size-wise this is safe to train on much smaller cards

* reason for making this model<br>
  There are some issues in the original model by larryvrh, which includes:
  * long sentence repetition, doesn't recongize breaks
  * dirty mix of numbers and periods
  * translates to or from english "sometimes"
  * a bit too big on smaller cards <br>
  They are generally all-parameter problems that i can only partially change with all-parameter finetune
  But I generally perfer to make a base model that doesn't have these issues to begin with. so here...

# 模型公开声明
* 这个模型由 mt5-translation-ja_zh 启发（其实就是在它上面改的），使用mt5-base，比原模型要小一些
* 使用了CCMatrix-v1-Ja_Zh， 1e-4学习率， 1 个epoch
* 大概在自己的2080ti 22g卡上跑了26小时，用高级的小卡会更快

* 制造这个模型的原因
  larryvrh的原模型很不错了，但是有一些小问题
  * 长句子会卷起来重复，而且不认识换行符
  * 数字和标点会乱写
  * 有时候会翻译或翻成英文，有时候会不翻
  * 对于小的机器来说有点大了 <br>
  当然还有别的问题，但是以上这些问题涉及到所有的param形状，我加lora上去它还是歪的，并不解决问题，像是之前那样整个模型finetune太精细不好把握
  所以还是重新炼个丹把上面的都解决掉

# A more precise example using it
# 使用指南
```python
from transformers import pipeline
model_name="iryneko571/mt5-base-translation-ja_zh"
#pipe = pipeline("translation",model=model_name,tokenizer=model_name,repetition_penalty=1.4,batch_size=1,max_length=256)
pipe = pipeline("translation",
  model=model_name,
  repetition_penalty=1.4,
  batch_size=1,
  max_length=256
  )

def translate_batch(batch, language='<-ja2zh->'): # batch is an array of string
    i=0 # quickly format the list
    while i<len(batch):
        batch[i]=f'{language} {batch[i]}'
        i+=1
    translated=pipe(batch)
    result=[]
    i=0
    while i<len(translated):
        result.append(translated[i]['translation_text'])
        i+=1
    return result

inputs=[]

print(translate_batch(inputs))
