Libtorch 1.9.1 and 1.7.1 releases with cuda fail to detect CUDA

I am trying to load a premade Yolo torchscript, which is failing. However, it is also failing to detect any CUDA at all. I have seen places describing a missing function call in messages a year old, is this problem still around? How do I rebuild under windows to fix this?

how about add “-INCLUDE: ? warp_size@cuda@at@@YAHXZ” in project property / linker / Add dependencies.
