KeyError: 'FastBEV is not in the models registry'

I installed mmcv1.4.0, mmdet 2.14.0, mmdet3d0.16.0 and successfully build the project. But when I run train.py it failed:

raise KeyError(
KeyError: 'FastBEV is not in the models registry'

I uninstalled and installed the dependencies but it didn't help. Can you help me implement it?
