Where did you install CUDA_HOME and CUDA_PATH?

I'm trying to install in windows via conda Installed CUDA 11.3 now these errors

Can I see a screenshot of your system and user environment variables

Try making a CUDA_HOME env variable with the same value as CUDA_PATH in both system and user variables (this way you can do it on both admin and user accounts)

Try installing ninja like in this issue https://github.com/NVlabs/tiny-cuda-nn/issues/169#issuecomment-1291990467

I also ran into this problem and tried many solutions. I found the solution here #1177 and installed tiny-cuda-nn thanks to this comment.

To document what I have done to get nerfstudio via conda to work properly:

1. Installed CUDA 11.7 and VS 2019 and deinstalled all other versions

2. Created a conda envoriment conda create --name nerfstudio -y python=3.8 conda activate nerfstudio python -m pip install --upgrade pip

3. Installed pytorch pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 -f https://download.pytorch.org/whl/torch_stable.html

4. Git cloned tiny-cuda-nn via the repo into miniconda3\envs\nerfstudio\Lib\site-packages git clone --recursive https://github.com/nvlabs/tiny-cuda-nn cd tiny-cuda-nn cmake . -B build cmake --build build --config RelWithDebInfo -j (cmake commands run in VS developer command prompt)

5. Installed nerfstudio pip install nerfstudio

6. Reinstalled tiny-cuda-nn via pip pip install git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torch

How tiny-cuda-nn was installed may not makes sense, but that's what worked in the end. Nerfstudio is now fully functional.

Closing, feel free to reopen if it is still and issue.

This one worked for me but I had to install CUDA 12.1.1 before runing cmake . -B build
