Hi, author, what's the difference between this repo with the torchvision DCN op. https://pytorch.org/vision/stable/_modules/torchvision/ops/deform_conv.html

The previous versions of DCNv2 in dcn_v2_cuda.cu use THCUDA which causes errors during setup.py. This repo uses AT Tensor functions which resolves the issue for higher pytorch and CUDA versions

@haak0 I am also curious about this. Honestly speaking I do not know.
