It was working fine previously, but suddenly this error occurred.

Hi ! Not 100% sure since I don't know your env. setting but I will go for a torch version update/downgrade you've made. If you do so, you would need to compile again the submodule diff_gaussian_rasterization (as well as the simple-knn one) Running

pip install -e submodules/* 

at the project root should do the trick 🙂
