problem when run the code

[Holmes-Alan]

When I run

python main_nerf.py data/fox --workspace trial_nerf --fp16 --ff --cuda_ray --gui

I got the following error,

Traceback (most recent call last):
File "C:\Users\zhisong_liu\Miniconda3\envs\ngp\lib\site-packages\torch\utils\cpp_extension.py", line 1740, in _run_ninja_build

raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

I tried to fix the problem on the '['ninja', '-v']' by '['ninja', '--version']', but I got another problem as,

ImportError: DLL load failed while importing _hash_encoder: The specified module could not be found.

What should I do?

Honestly I'm haven't tested it on window, so I'm not familiar with the error.
Could you verify the environment, e.g., torch and ninja version? Could you build other pytorch CUDA extensions, like the tiny-cuda-nn by pip install git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torch?
(Still, I would recommend trying to run the program in Linux systems, such as the WSL)
