When I test, there is a error "ModuleNotFoundError: No module named 'mmcv._ext'".
I have no idea how to deal.

Possibly due to the mismatched version of mmcv related tools. Make sure the following is correctly compiled:

git clone https://github.com/open-mmlab/mmdetection3d.git
cd mmdetection3d
git checkout v0.17.1 # Other versions may not be compatible.
python setup.py install
