Problem with your windows machine c++ compiler tools. cl.exe not found basically. try some of the instructions in the docs for windows install
Had to do a reinstall of the visual studio due to the classic 'vcvars64.bat'. Did not reinstall CUDA after. Could that be the issue?
It's just that the cuda backend for nerfacto, i.e. tinycudann, and the cuda backend of splatfacto, i.e. gsplat, are distinct and have their own install methods. gsplat info can be found here. Looks like it is just unable to find some cpp compiler linker, which the error says. I am not a windows user, but maybe googling something like "cl.exe not found, Windows" could guide you to better sources for debugging.
Please try:
pip uninstall gsplat
pip install git+https://github.com/nerfstudio-project/gsplat.git
And restart the terminal/shell/prompt
