I have an issue when running demo.py and main_CenterPose.py It seems to be a problem of DCNv2 I'm running on windows 10, python 3.6.13

have anyone got it running sucessfully?

Sorry about that. I have not tried it on Windows before. So it may not work.

You can try some other backbone networks if needed.

Did you compile the backbone network by executing make.sh in src/lib/models/networks/DCNv2? Without this step I get the same error on Ubuntu.
