分析

我的基本环境

• python -V 我是 python 3.10
• transformers==4.6.0

报错原因

huggingface transformer 这个包，依赖 tokenizers包， tokenizers 使用了 Rust 多线程加速处理数据集。
这个是Rust的Bug。

解决办法

1. 降低python版本， 比如使用 python3.8

2. 修改源码再编译，在源码上修改依赖的 tokenizers的版本
   
   然后使用 python setup.py install装包

3. 使用最新版的 transformers包，修改咱们自己项目的代码。修改咱们项目内报错位置的代码，使其支持最新版的 transformers。
