Error while starting Gsplat training via Nerfstudio #121

Closed breezanil closed 6 months ago

breezanil commented 8 months ago

Hello, I'm trying to get Gsplat file from a recording made with Spectacular Rec App on Iphone. When I follow the tutorial, I get NERF properly from nerfstudio, but when I run the command ns-train gaussian-splatting --data \directory\ I encounter an error :

C:\Users\anaconda3\envs\nerfstudio\lib\site-packages\torch\utils\cpp_extension.py:383: UserWarning: Error checking compiler version for cl: [WinError 2] can't find the specified file

and then

File "C:\Users\anaconda3\envs\nerfstudio\lib\site-packages\gsplat\cuda_backend.py", line 56, in from gsplat import csrc as _C ImportError: cannot import name 'csrc' from 'gsplat' (C:\Users\breez\anaconda3\envs\nerfstudio\lib\site-packages\gsplat__init__.py)

I updated Nerfstudio and reinstalled Pytorch but it still doens't work. Any idea ? Sorry I'm not really litterate in those Python/Cuda stuff...

Thanks, breezanil.

Thanks oseiskar, it worked. I uninstalled gsplat, then reistalled gsplat 0.1.0 from source, as mentionned in the post.
