about DCNv2 compiling

[dawnlh]

In the Dependencies and Installation part, you mentioned that:

Deformable Convolution. We use Charles Shang's DCNv2 implementation. Please first compile it.

cd ./codes/models/modules/DCNv2
bash make.sh

but there is no "modules" directory in this path, so do you mean I should download it from 'Charles Shang's DCNv2' repository and put it in this path then compile it myself? (if I run the code directly, I will encounter the error--"Failed to import DCNv2 module")

Thanks a lot

Hi, you can change to the 'dev' branch, then you will find "modules" directory.

@dawnlh We have updated the repo to use dcn in mmdetection. But we did not update the readme, so it raised the confusion. Now we have updated the readme.

@xinntao Is there any difference between using DCNv2 and DCN? DCNv2 performs better？

@townblack oh, I got it, thanks!
