Dear Bowen,I meet a problem in runing this code.TypeError: BRNet: CAVoteHead: cfg must be a dict, but got <class 'NoneType'> My mmdet3D version is v0.15.0.

Have you ever met this problem?
By the way,my mmdet3D version is v0.15.0. for NVIDIA 30 series GPU.

I don't try to use mmdet3d v0.15.0, and just run the code using mmdet3d v0.11.0.

You may refer to this issue #5, where I have provided the conda env config file.
