unable to get model working
(sugar) khfifi@jensen:~/SuGaR$ python train.py -s /home/khfifi/tryinggauss -c /home/khfifi/gausstomesh -r "sdf"
Traceback (most recent call last):

i'm trying to follow the steps, i'm on the optimization of sugar, and I keep running into this error. thank you to whoever replies.

are you clone git clone https://github.com/Anttwo/SuGaR.git --recursive ?? not git clone https://github.com/Anttwo/SuGaR.git
Apparently the cause of this issue is a mismatch between PyTorch versions. What worked for me was to remove the submodule (simple_knn and diff_gaussian_rasterization) folders entirely (if you did not make changes in them of course :-), then load them again through git submodule update --init --recursive and reinstall the modules through
pip install submodules/simple-knn/
pip install submodules/diff-gaussian-rasterization/
There may be better ways that delve deeper into the 'why' of the problem. But this worked for me.
