A simple version of Deformable Convolution Network V2
This project inherits from https://github.com/developer0hye/PyTorch-Deformable-Convolution-v2. I also referred the official DCNv2 project.
You don't have to worry about how to install DCNv2 anymore, you just need to from DCN.dcnv2 import DeformableConv2d as DCN to use DCNv2.
It is very easy and convenient.
This project has passed the test of Torch >= 1.9.1 and Torchvision >= 0.10.1.
