Motivation

I have a NVidea 5080 graphics card great new card. But not supported by older Python versions (like the 3.11). The PyTorch en CUDA-drivers are just not working with these versions. This means that I am unable to install this project. Which is a shame.

I run latest nighty Torch 2.9.0.dev20250714+cu128 and Python version: 3.12.3 . Everything works exept Nunchaku. I cnat use whees it's build for 2.7 and I can't build new one because of numpy not supported on 3.12 python and I cunt downgrade python Torch not supported 3.11 . So please update Nunchaku to Torch 2.9

We are waiting for the official release of torch 2.8. Currently, we do not recommend torch 2.9 as it is a nightly version.

I was able to use Nunchaku with Python 3.12, PyTorch 2.8.0 CUDA 12.9

the worflow to install nunchaku wheel now has one for this configuration.
I just manually compiled xformers and apex and sageattention(2++) and that's all I needed

official torch 2.8 wheels are supported. torch 2.9 nightly wheels are also supported. Please try again.
