Failed to build diff_gaussian_rasterization

[guevara12345]

1. I have already install pytorch and cuda 11.6 as environment.yml says, but I used the vs studio 2022.
2. I have use the miniconda to activate the env, and here comes the error as below.
3. I trying to find where this error happens, and I find this happen when conda tries to build c++ extention for pytorch.
4. so I try to build the diff-gaussian-rasterization by myself. cd to /gaussian-splatting/submodules/diff-gaussian-rasterization, then run pip install .
5. same error happen as below, and I think this error message says that backward.obj is not been build. and I don't know why cl build this the backward.cu fail, and there is not futher more info,will change to vs studio 2019 helps?

note: This error originates from a subprocess, and is likely not a problem with pip.

I doubt this would be fixed by using vs studio 2019

The linker error is https://learn.microsoft.com/en-us/cpp/error-messages/tool-errors/linker-tools-error-lnk1181?view=msvc-170 which means cannot open input file 'filename'.

Do you see that backward.obj is created in the following path?

"E:\my_proj\gaussian-splatting\submodules\diff-gaussian-rasterization\build\temp.win-amd64-cpython-37\Release\cuda_rasterizer\backward.obj"

Also it seems a bit strange that it has some uni-code characters before the path in the link:

LINK : fatal error LNK1181: 无法打开输入文件“E:\my_proj\gaussian-splatting\submodules\diff-gaussian-rasterization\build\temp.win-amd64-cpython-37\Release\cuda_rasterizer\backward.obj”

thanks，I solve this problem by install cuda before vs 2022. but I got some new troble to build diff_gaussian_rasterization: https://forums.developer.nvidia.com/t/problems-with-latest-vs2022-update/294150 still trying to find out the solution
