MiniGPT-4中文支持方案

介绍

MiniGPT-4本身的语言大模型是基于LlaMA的,由于该模型对中文的支持不好。因此想了个折中的办法: 在模型的输入和输出分别加了一个翻译模型,用户输入(中文)-> 翻译模型(Chs-Eng) -> 大模型 -> 翻译模型(Eng-Chs)->返回结果

tokenizer_zh2en = AutoTokenizer.from_pretrained("facebook/nllb-200-distilled-600M")
model_zh2en = AutoModelForSeq2SeqLM.from_pretrained("facebook/nllb-200-distilled-600M")

translatorEng2Zho = pipeline(
    'translation',
    model=model_zh2en,
    tokenizer=tokenizer_zh2en,
    src_lang='eng_Latn',
    tgt_lang='zho_Hans',
    max_length=1024
)

translatorZho2Eng = pipeline(
    'translation',
    model=model_zh2en,
    tokenizer=tokenizer_zh2en,
    tgt_lang='eng_Latn',
    src_lang='zho_Hans',
    max_length=1024
)

如何运行

python3 demo_zh.py --cfg-path eval_configs/minigpt4_eval.yaml  --gpu-id 0

效果图

安装踩坑记录

  • RuntimeError: The size of tensor a (32000) must match the size of tensor b (32001) at non-singleton dimension 0 解决方案:vicuna模型需要下载vicuna-7b-delta-v1.1,老的模型会报错 参考 MiniGPT-4/issues/74 感谢 Cola1999 给与的支持!
  • Probability tensor contains either inf, nan or element < 0 解决方案:修改eval_configs/minigpt4_eval.yaml,将low_resource设置为False 参考MiniGPT-4/issues/74

TODO

  • 替换LlaMA模型为国产大模型,支持更高质量的中文交互
