How to setup a Conda/Pytorch enviroment for using ComfyUI's 3D-Pack

Spoiler allert the solution was to target CUDA 11.8 (PyTorch 2.2.0+)

  1. Make sure you have git, git-lfs, mesa and CUDA-11-8 installed at a OS level
sudo apt install git git-lfs cuda-11-8 mesa-utils mesa-common-dev libegl1-mesa-dev libgles2-mesa-dev
