when i attempt to fix the nodes it does this among other things:

Installing collected packages: torchvision
Attempting uninstall: torchvision
Found existing installation: torchvision 0.21.0+cu126
Uninstalling torchvision-0.21.0+cu126:
Successfully uninstalled torchvision-0.21.0+cu126
Successfully installed torchvision-0.20.1+cu124

After it finishes it does this:

[ComfyUI-Manager] restore PyTorch to 2.6.0+cu126

Is there any way to stop it from reverting?

i recommend you to use cuda 12.4 or cuda 12.8

[tvmrm]

Thanks! It was a python version problem, i had to get an old comfy to get this going. Only to realize that Trellis gives the best results and it's much better to install just the standalone Trellis by itself and forego the whole comfy complication.

@tvmrm what do you think about triposg and hunyuan v2? you may try them in dev branch

[tvmrm]

I briefly tried Tripo and it didn't produce anything useful, Hun is better, mostly because the workflow has an ability to extract the texture right away. But the precision is about the same or slightly lower than Trellis single image. Nothing comes even close to Trellis multi image.
