2 years ago As explained here https://forums.developer.nvidia.com/t/strange-link-error-seen-by-multiple-people-while-building-pytorch-cpp-cuda-extensions/145261/2 the issue happens because long resolves to 32-bit int on Windows as opposed to 64-bit long long on Linux. Replace the two occurrences of long in sigmoid_focal_loss_cuda.cu with int64_t and it will work fine.
Facing issue when running "pip install -v -e ." on windows machine config{ windows:10 cuda 10.2 python:3.8}
