Compilation error occurred in diff_gaussian_rasterization

[StringerYwh00]

Your setup file seems incomplete

Hi, sorry for the late response.

We think this issue is similar to a previous problem mentioned here #4. All of our experiments and implementations were done in the environment of ubuntu :20.04, python: 3.8.16, and cuda:12.1. The setup.py you have mentioned is only for jit-compilation of the cuda rasterizer and it did not cause a problem in our environment. Could you please provide us which environment you are working on? (ubuntu, cuda)

Thanks, Jaewoo.

I also have encountered the problem:

I have solved the problem by reinstall pytorch.
