Hm, is it necessary to install gsplat from source? Shouldn't it be installed automatically from pip install nerfstudio?

nerfstudio/pyproject.toml

Line 66 in 90cc4f1

"gsplat==1.0.0",

I think might only Windows need to install it from source because the vc environments.

@KevinXu02 @brentyi I am installing nerfsudio on ubuntu and if i install gsplat from pip then I am getting this error:

  File "/home/hd/Desktop/workspace/ns/.venv/lib/python3.10/site-packages/gsplat/cuda/_wrapper.py", line 12, in call_cuda
    return getattr(_C, name)(*args, **kwargs)
AttributeError: 'NoneType' object has no attribute 'fully_fused_projection_fwd'

I need to investigate the failure building cases of gsplat on windows.. Adding it to my TODO list

I just noticed this PR, my PR #3333 has some more background on gsplat on Windows (and is the polar opposite of this PR lol).

Manually adding gsplat on Linux should not be necessary and there's probably something else going on, the reason it was added to the Windows documentation has to do with Visual Studio being a pain.

Including manually installing gsplat in the documentation should be avoided if possible, as this will break on new Nerfstudio/Gsplat releases and the documentation will need to be updated each update.

@SharkWipf if you already included this PR fixes then we can close this PR.
