weird mmcv version error

[YangHan-Morningstar]

Hi there, thanks for your great work! When I'm training, my packages' version are all right, but I still get an error:

AssertionError: MMCV==1.4.8 is used but incompatible. Please install mmcv>=1.2.4, <=1.4.0.

When I reinstall using 'pip install mmcv-full==1.2.5', I get another similar error which says ''MMCV==1.2.5 is used but incompatible. Please install......''

Could your help me?

By the way, I reinstall my whole environment and the init mmcv's version is 1.4.0, but still get the similar error just like above. There is always this version error....

Hi there, we can find the correct versions in /.../mmdet/init.py and other init.py. If you have installed mmsegmentation, you should make sure your mmcv's version also correct in /.../mmseg/init.py.

Hi,

I've also encountered the same problem when I tried to prepare data with python tools/create_data.py nuscenes --root-path ./data/nuscenes --out-dir ./data/nuscenes --extra-tag nuscenes. Unfortunately, all combinations between mmcv (1.2.4 to 1.3.0) and mmdet (2.5.0 to 3.0.0) have been tried and none of them worked.

Could you please share you version info if that on your side works?

(More info of mine: 2 A6000 GPU Ubuntu 20.04 CUDA 11.1 PyTorch 1.9.1 mmdet3d 0.11.0)

Thanks :)
