When you use the conda list to view the environment, does it show that the dcn has been successfully installed dcn

Hi, @obouluh. I use DCNv2 from lbin/DCNv2 which contains several torch versions. I use torch1.7 and successfully build DCNv2. If that repo doesn't fit your requirement, you can also try jinfagang/DCNv2_latest.

Hi, I found that using mmcv.ops.ModulatedDeformConv2dPack instead of DCNv2 can also load pre-training weights without any problems. And mmcv-full is very easy to be installed. You can try it. @obouluh
