In the docker, when I want to transform the pth to onnx:
ImportError: cannot import name 'iou3d_cuda' from partially initialized module 'third_party.bev_mmdet3d.ops.iou3d' (most likely due to a circular import)(workspace/./third_party/bev_mmdet3d/opts/iou3d/init.py)

It is solved for me by following #2
It needs to be change to

cd ${PROJECT_DIR}/third_party/bev_mmdet3d
python setup.py build develop
