to compile tinycudann you need to install CUDA and visualstudio c++ desktop module. After compiling you can use nerfstudio without cuda and visualstudio

In my case, I solved it by changing gcc-7 and g++-7 to gcc-9 and g++-9

Updating to gcc/g++ 9 worked for me too. These instructions were helpful in accomplishing that, https://linuxconfig.org/how-to-switch-between-multiple-gcc-and-g-compiler-versions-on-ubuntu-20-04-lts-focal-fossa

While following the quickstart guide on Windows 10 I had a similar issue ending with:

          raise RuntimeError(message) from e
      RuntimeError: Error compiling objects for extension

Building tinycudann manually worked: pip install git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torch

Perhaps the prebuilt wheel is broken again? Or maybe I had something funky in my setup.

You always need to compile tinycudann during installing
