conda环境下cannot import name ‘dispatch_model‘ from ‘accelerate‘ 问题解决

1 程序运行报错的错误输出

错误信息显示如下：

File "D:\git\voice-transeformer\text\ty_pinyin.py", 
line 9, in  from bert import TTSProsody File "D:\git\voice-transeformer\bert\__init__.py",
line 1, in  from .ProsodyModel import TTSProsody File "D:\git\voice-transeformer\bert\ProsodyModel.py",

2 问题分析与解决

从报错信息来看，大概率是transformers与accelerate的版本不匹配的所致，更新两个组件的版本如下：

pip install transformers==4.28.1

pip install accelerate==0.20.3

再次运行程序，不再报错，问题解决。
