Incompatible versions

[epotein0vintrume]

I can't install wheels 'couse of the incompatible versions:

Python 3.13.6
Torch: 2.8.0+cu129
Torch.version.cuda: 12.9

Running this:
python_embeded\python.exe -m pip install ComfyUI\custom_nodes\ComfyUI-Hunyuan3DWrapper\wheels\custom_rasterizer-0.1.0+torch260.cuda126-cp312-cp312-win_amd64.whl
Gives me this problem:
ERROR: custom_rasterizer-0.1.0+torch260.cuda126-cp312-cp312-win_amd64.whl is not a supported wheel on this platform.

Anyone can help?

Hi! I had the same problem but with Torch: 2.8.0+cu128
I solved it by following the instructions for building my own version of custom_rasterizer. (I've been in agony for almost 2 days.)

From the easy one, I can suggest downloading my build for cu128, you can take it in my fork (but you will need to change your Torch from 2.8.0+cu129 to 2.8.0+cu128) #182

Of the difficult ones, here is a comment on which I compiled my version. #92 (comment)

Thank you very much!

i'm trying to build my own version but i'm stuck
Also i've never programmed

Hey @epotein0vintrume, could you please elaborate? I'm wondering if you have a similar problem (getting hy3d custom_rasterizer to work with PyTorch 2.8+ and Cuda 12.8+, on an RTX 50 series GPU). I'm going over it with ClaudeAI, and it seems convinced that the hy3d package will need to be updated before this configuration can work.

Can you state your PyTorch, Cuda versions and your GPU? Thanks!

Scratch that! @DaniilVdovin I found your 280 wheel! Thank you for this!

That fixed my RTX 50 problem.

For anyone else here that is trying to get this working on an RTX 50 card, this is a fix:

• install cuda 12.8
• install pytorch 2.8.0
• get DaniilVdovin's 280 wheel: "custom_rasterizer-0.1.0+torch280.cuda128-cp312-cp312-win_amd64.whl" | [https://github.com/DaniilVdovin/ComfyUI-Hunyuan3DWrapper/blob/9021bbc11ac8af1c219ab7a967869b57837f7903/wheels/custom_rasterizer-0.1.0%2Btorch280.cuda128-cp312-cp312-win_amd64.whl]
