gsplat installation dependency may need clarification? ImportError: cannot import name 'csrc' from 'gsplat'

[luckui]

Description
When trying to use this project on Windows with an RTX 4080, I noticed that the documentation recommends torch 2.8.0. However, in practice, GSPLAT's CUDA extensions do not seem to compile successfully with PyTorch 2.8.0.

Issues encountered

• Errors like ImportError: cannot import name 'csrc' from 'gsplat'
• Runtime errors during CUDA extension compilation
• _jit_compile() missing 2 required positional arguments: 'verbose' and 'with_sycl'

It would be helpful if the documentation or requirements could clarify:

• The currently recommended PyTorch + CUDA combination
• That using the latest PyTorch version may cause GSPLAT compilation to fail

Environment

• Windows 11
• Python 3.13
• PyTorch 2.8.0+ CUDA 12.4
• RTX 4080

Community examples and some testing indicate that GSPLAT extensions can successfully build with torch 2.1.2 + CUDA 11.8. This might be useful information for users trying to run this project on Windows. nerfstudio-project/gsplat#311
Am I out of date?

Request
I am looking for guidance or instructions on how to successfully install and compile GSPLAT under these conditions. Any help would be appreciated.
