Fail to install diff-gaussian-rasterization

[evearmadillo]

Hello, I've followed https://github.com/henrypearce4D advice on adding VS path to env variables, but I ran into this error:

(base) C:\Users\evebo\gaussian-splatting>git submodule update --init --recursive

In the gaussian-renderer init.py code there're missing imports from GaussianRasterization.

How can I resolve this? Thank you in advance!

Do you have torch installed ? Otherwise you can not import CUDA extensions in setup.py

Do you have torch installed ? Otherwise you can not import CUDA extensions in setup.py

>>> import torch
>>> print ("PyTorch version:" , torch.__version__)
PyTorch version: 1.12.1
>>> print("CUDA available:" , torch.cuda.is_available())
CUDA available: True
>>>

Yes, pytorch is 1.12.1, or should I install something extra? I'm so confused, it always comes up with the same error

Hi, from your log, you're in the base environment of conda while the yml file of the guide automatically creates a gaussian_splatting env. Could this be the problem? Maybe try conda activate gaussian_splatting first.
