安装mmengine出现报错

mim install mmengine

详细报错内容如下：

Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 602, in _exec
  File "<frozen zipimport>", line 259, in load_module
  File "/usr/share/python-wheels/pkg_resources-0.0.0-py2.py3-none-any.whl/pkg_resources/__init__.py", line 57, in <module>
ImportError: cannot import name 'six' from 'pkg_resources.extern' (/usr/local/lib/python3.8/dist-packages/pkg_resources/extern/__init__.py)

During handling of the above exception, another exception occurred:

解决方案

给pip降低版本

python -m pip install pip~=19.0

之后一切正常
