Hi, I am trying to compile a torch extension on Windows GitHub - openmm/NNPOps: High-performance operations for neural network potentials
but I am getting errors: error C2872: 'std': ambiguous symbol
getNeighborPairsCUDA.cu

It seems to me like the std definition of c10 here pytorch/c10/cuda/CUDAStream.h at main · pytorch/pytorch · GitHub is causing collisions with:
- the std definition in the Microsoft headers and
- the std definition in the torch dynamo headers
This doesn’t seem to cause any issues on Linux surprisingly. Is there any way to fix these issues with the Windows builds?
