Install ComfyUI easily on Ubuntu / WSL2: one-command universal installer with NVIDIA, AMD, and Intel GPU support

Hi everyone - I made a universal Bash installer to make installing ComfyUI easier on native Ubuntu and Ubuntu inside WSL2. GitHub repo: It automatically detects your setup and installs the right ComfyUI environment for: NVIDIA - CUDA AMD - ROCm Intel - XPU WSL2 - GPU-aware setup for Windows users running Ubuntu in WSL The script installs or updates ComfyUI, creates a clean Python virtual environment, installs the matching PyTorch GPU build, verifies GPU access, and creates launchers so you can start ComfyUI easily.
