Anyone knows how to resolve this? Thank you!

I have the same problem. It's related to the version of mmdet-3d and mmcv Could you please provide a suggestion? Thanks

@whai362 Thanks for your awesome work. I also meet the problem. I install mmdetection3d following this official install tutorial [https://github.com/fundamentalvision/BEVFormer/blob/master/docs/install.md], mmcv-full = 1.4.0 , mmdet = 2.14.0 mmsegmentation = 0.14.1 mmdet3d = v0.17.1 I install all the requirement without error, but I meet the bug. the same as the issue. when i run the Prepare nuScenes Data , i got the error. python tools/create_data.py nuscenes --root-path ./data/nuscenes --out-dir ./data/nuscenes --extra-tag nuscenes --version v1.0 -mini --canbus ./data the error info is as follows.
