To clarify, cl.exe's directory is in my path, and the full, verbose output is:

I see the same issue.

My local directory is in the gaussian-splatting repro

I run
pip install submodules\diff-gaussian-rasterization

from my conda environment

based on the instructions here: https://github.com/jonstephens85/gaussian-splatting-Windows#installing-the-optimizer

the error:

Does the python version I use cause a problem? I have Python 3.8.17

cl.exe shows the c++ compiler is installed

I also created a new conda environment and followed the instructions here:
https://github.com/jonstephens85/gaussian-splatting-Windows
but the same problem happens, just from inside a larger script / build / process. simple-knn fails similarly

[RoyDubnium]

reinstalling cuda did not seem to help in my case. While it did allow for cmake to run without errors, pip still failed to install it.

[Kosmokleaner]

Update: My issue was resolved by installing CUDA 11.8 from here:

https://developer.nvidia.com/cuda-11-8-0-download-archive?target_os=Windows&target_arch=x86_64&target_version=11&target_type=exe_local

the conda CUDA version seemed to not matter in this case.

I had to close the command line and try again.

I found it by going into gaussian-splatting\submodules\diff-gaussian-rasterization
and calling:
cmake -Bbuild

The error there:
The CUDA Toolkit v11.8 directory '' does not exist. Please verify the CUDA Toolkit is installed properly

Helped me.

[Cazforshort]

I can confirm I have the same exact issue

Thats after reinstalling CUDA 11.8 and then trying 11.7 too.

me too

[Natalia19892210]

You have to restart PC after instalation and it helps.

[ertz10]

One not so obvious issue I came along was hidden in the cuda environment variable:
CUDA_HOME='C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8;'
This version constantly failed with the above error message: 'The system cannot find the file specified'

The solution for at least this error message was to remove the semi-colon at the end of the environment path. It was just added because I had multi-lines in the CUDA_HOME variable, which eventually added a semi-colon when clicking 'OK'.
So just delete the path again and readd just one line.

Hi guys, I can provide another cue to solve your problem. Inspired by @RoyDubnium , I tried to use cmake to install the package, and I successed to address the problem.
In my case, there's no cuda toolset found. The problem is raised by the lacking of cuda configure in Microsoft Visual Studio\2022\BuildTools\MSBuild\Microsoft\VC\v170\BuildCustomizations, which can be find in C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\vxx.x\extras\visual_studio_integration\MSBuildExtensions. You can find more detailed discussion in websites. Hope it would help.

This issue could be solved through copying the cuda files, but some others might meet other problem. In my case, the new error is caused by cofliction between cudatoolkit=11.6 and the real cuda version of my windows system.
