transformers==4.42.0版本下，自动安装模型时出现一个BUG（自动从Hugging Faces上下载）。

2025-07-02 14:07:08,641 - __main__ - ERROR - 模型加载失败: Failed to import transformers.models.llama.tokenization_llama_fast because of the following error (look up to see its traceback):

其实表面上看就知道这个是一个字符编码的问题，但是网上没有什么简单的针对方案。其实你找到这个文件，打开一开似乎还看不出 tokenization_llama_fast.py, line 120 有什么问题，而且你还会发现这一行其实就是一个注释，最简单的方式就是清除注释，之后运行就正常了，非常简单。
