import DCN failed

Notice

When executing the training command, import DCN failed will be displayed at the beginning. How to fix it? Thanks!

If you have already identified the reason, you can provide the information here. If you are willing to create a PR to fix it, please also leave a comment here and that would be much appreciated!

I also have the same problem, did you solve it, can you tell me how to solve it.Thank you!

I still have this problem,but It does not affect the run of the code.

I am also experiencing this issue using the following environment:

应该是DCNv2模块没有加载成功，DCNv2是一个python包，是deformable convolution ，但是这个包比较难装，然后mmcv已经封装好了，可以直接使用mmcv里面的DCN，我查到的资料是这样的。
