Failed building wheel for diff_gaussian_rasterization

[ErisRolo]

Hi, I found that the gaussian_splatting directory in the open-source code does not contain a submodules directory, making it impossible to directly create an environment using the YML file. Therefore, I have attempted to create it manually. I've noticed that in the .gitmodules file, the URL for the diff-gaussian-rasterization module is specified as "https://github.com/slothfulxtx/diff-gaussian-rasterization.git", and the generated dependency name is "diff_gauss". However, in the provided source code, specifically in the gaussian_splatting/gaussianrenderer/__init_\.py file, the import statement still uses diff_gaussian_rasterization. Could you please explain if the submodule being used is indeed the same as the one in the original 3DGS project?

Hi, thanks for pointing out this issue. The problem was that the gitignore file was removing the submodules. This is now fixed. If you clone the repository again using the --recursive flag, it should now install all submodules.

The "https://github.com/slothfulxtx/diff-gaussian-rasterization.git" was an artifact from prior experiments with depth. This is now replaced with the official submodule used in 3DGS. Let me know if it is working now

After switching to the original 3DGS rasterization submodule I could not install it on my machine any longer due to CUDA_HOME issues. I changed it back to the diff-gaussian with depth information and fixed the code accordingly

Hi, thank you for your help, but there are still error messages.

I will try the original 3DGS rasterization submodule, but I'm not sure if it works.

I switched to the original 3DGS rasterization submodule, and then it worked.

But can you fix the error mentioned above? Thank you.

Additionally, I noticed that although the modified .gitmodules file points the diff-gaussian-rasterization module to "https://github.com/slothfulxtx/diff-gaussian-rasterization.git", the uploaded submodules file points the module URL to "https://github.com/slothfulxtx/diff-gaussian-rasterization/tree/59f5f77e3ddbac3ed9db93ec2cfe99ed6c5d121d". The latter does not differ from the original version of the 3DGS module. Should the contents of the submodules be modified?
