Error when training splatfacto: "ninja: build stopped: subcommand failed" (Windows)

[elliotmarks06]

I am trying to train a gausian splat, but it always fails during the gsplat: Setting up CUDA with MAX_JOBS=10 stage.
After dumping a bunch of information, it fails with the error ninja: build stopped: subcommand failed.

I originally thought it was an error with Visual Vtudio 2019, so I did a full reinstall with 2022 17.8 which didn't seem to fix it.

I have copied the end of the log below, but the full terminal output can be referenced here: https://pastebin.com/s33PEqyX

Thanks for your help!

I am facing the same problem in windows, have you found a solution by now?

I was using CUDA 11.8 facing the same problem and solved.

I downloaded cub version 1.17 and deleted the cub folder in the CUDA toolkit and replaced it with the cub 1.17: C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.8/include/cub.

Then I set CUB_HOME= C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\include.

And it worked!

Weird! I am having the same issues. I was using cuda 11.8 with other projects. During install of nerfstudio I had issues compiling tiny-cuda-nn, something with VS2019 vs VS2022. I finally managed to build tiny-cuda-nn using Cuda 11.7.
Training nerfs / making videos works without an issue, but when I ty to train a splat I am also gettging "ninja: build stopped: subcommand failed." I thought the splatting stuff migh require Cuda 11.8 but that does not match Wesilaus observations.
