Quick Guide For Fixing/Installing Python, PyTorch, CUDA, Triton, Sage Attention and Flash Attention For Local AI Image Generation

Quick Guide For Fixing/Installing Python, PyTorch, CUDA, Triton, Sage Attention and Flash Attention For Local AI Image Generation

With all the new local image & video generation tools coming out I've been seeing a lot of posts and error threads being opened for various issues with cuda/pytorch/sage attantion/triton/flash attention. I was tired of digging links up so I initially made this as a cheat sheet for myself but expanded it with hopes that this will help some of you get your venvs and systems running smoothly.

  1. Check Installed Python Versions
  2. Set Default Python Version by Changing PATH
  3. Installing VS Build Tools
  4. Check the Currently Active CUDA Version
