It seems that there is a syntax error in your config, could you please provide your config and we will check it.

我看的问题，推测是FormatCode这个函数，没有verify=True这个参数.

我看我本地安装的yapf是0.40.2

我没有编辑config，直接用缺省的qwen-*几个试了一下，都是同样的错误信息。

1475                 text, _ = FormatCode(
1476                     text, style_config=yapf_style, verify=True)

改成

1475                 text, _ = FormatCode(
1476                     text, style_config=yapf_style)

就能正常运行了.

是的，确实是yapf版本的问题，0.40.2移除了verify参数。

open-mmlab/mmengine#1365 已经解决了这一问题，可以考虑从源码重新安装MMEngine

pip uninstall mmengine; pip install git+https://github.com/open-mmlab/mmengine.git
