Installation in Windows 10

[weizmanl]

Hi,

I have Windows 10 and I have been trying to install torchsparse, but no success.

When I run pip things compile, but linkage fails. It says:
Creating library C:\Users\WeizmanL\AppData\Local\Temp\pip-req-build-6qzmrtnx\build\temp.win-amd64-3.8\Release\torchsparse/src\torchsparse_cuda.cp38-win_amd64.lib and object C:\Users\WeizmanL\AppData\Local\Temp\pip-req-build-6qzmrtnx\build\temp.win-amd64-3.8\Release\torchsparse/src\torchsparse_cuda.cp38-win_amd64.exp

Any ideas?

Thank you

replace long with int64_t.
