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.

In This Guide:

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
