Some question about the version about mmdet3d and demo

[YuRui-Learning]

Hello, thank you very much for this excellent work. I have greatly benefited from reading your article. However, I have encountered some issues when running the code.
Firstly, in the article, it mentioned that the recommended version of MMDetection3D is 0.11.0. Should I follow the installation instructions provided or export the Python path like(export PYTHONPATH=${PYTHONPATH}:/root/MSMDFusion-main)?
Secondly, when I ran the demo, I encountered the following problem.When i git clone mmdet3d and pip install -v -e , i get this bug

In fact, I have placed the required mmdet3d in this repo to prevent version incompatible problem. You can directly build the mmdet3d in this repo.
