No module named 'diff_gaussian_rasterization'

[ctankep]

Hi ,

This looks interesting and pip install -r requirements.txt
went fine. Then on running " comfy ui " the diff_gaussian_rasterization
module can't be imported in `main_3dgs_renderer' ..

How can I install `diff_gaussian_rasterization' , which seems to be a submodule of the INRIA 'gaussian splitting' repo ? I'll try installing from that repo though this has the actual code : [ https://github.com/graphdeco-inria/diff-gaussian-rasterization ]

Thanks !

Did you run the install.bat? I am using an improved version of gaussian rasterization which supports alpha & depth render

git clone --recursive https://github.com/ashawkey/diff-gaussian-rasterization
pip install ./diff-gaussian-rasterization

Please follow the install instruction for how to install diff_gaussian_rasterizationand other necessary packages
