Adding documentation about compiling extension with CUDA 11.5 and Windows Example of failure: https://github.com/pytorch/pytorch/runs/4408796098?check_suite_focus=true Note: Don't use torch/extension.h In CUDA 11.5 under windows in your C++ code: Use aten instead of torch interface in all cuda 11.5 code under windows. It has been failing with errors, due to a bug in nvcc. Example use: >>> #include <ATen/ATen.h> >>> at::Tensor SigmoidAlphaBlendForwardCuda(....) Instead of: >>> #include <torch/extension.h> >>> torch::Tensor SigmoidAlphaBlendForwardCuda(...) Currently open issue for nvcc bug: #69460 Complete Workaround code example: facebookresearch/pytorch3d@cb170ac
