AssertionError: MMCV==0.2.16 is used but incompatible. Please install mmcv>=1.2.4, <=1.4.0.

Thanks for the amazing work and code. I am trying to follow the setup instructions. When I run the inference_demo.py I got: AssertionError: MMCV==0.2.16 is used but incompatible. Please install mmcv>=1.2.4, <=1.4.0.

Any suggestions ?.

@mathmax12 Where is the AssertionError coming from? It looks like an mmdet-related error - do you already have another version of mmdet installed that could be interfering with the one included with this repo?

If so, maybe this could help: https://github.com/WXinlong/SOLO/blob/master/docs/INSTALL.md#using-multiple-mmdetection-versions

@danielcrane Thanks for the info. The error comes from mmdet package. I tried different version but the issue persist.

@mathmax12 mmdet is included in this repo, have you tried uninstalling all other versions of mmdet that you may have elsewhere (i.e. via pip), and just relying on the one in this repo? (no installation required, it's imported directly from the folder)

[mathmax12]

@danielcrane I uninstall the mmdet When I rerun the pip install -v -e . I got this issue:

Ah, unfortunately I've not installed it on Windows before, so I can't help much there I'm afraid.

[mathmax12]

Thanks a lot anyway :)
