The installation of mmrotate will install an additional mmcv.

[liuyanyi]

Describe the bug
The installation of mmrotate will install an additional mmcv although I have mmcv-full installed.

The output of the pip list command is as follows:

mmcv                1.4.5
mmcv-full           1.4.5
mmdet               2.21.0
mmrotate            0.1.0     

Reproduction

1. What command or script did you run?

pip install -v -e .

Bug fix

Compared with other mmlab project, i think the difference may appeare in requirements/runtime.txt, maybe remove mmcv in runtime.txt can fix it.

This is because only the latest version of mmcv (1.4.5) contains all the operators required by MMRotate.

Thanks for your reply, I follow the installation guide in a new conda environment, there are still two mmcv in pip list. Both training and testing work fine.
But on mmcv's document, it says both versions in the same environment may encounter errors, should I uninstall one of them?

I also have this problem, bug training and working fine....

I was tried modified the requirements/runtime.txt, change the mmcv to mmcv-full, can fix this problem.
In my conda env just one mmcv-full package, and run demo was fine.

Hi @liufeinuaa ,
Thanks for your solution. Would you like to create a PR to fix that?
