Everyone posting their pip/build/runtime errors is everything that's wrong with tooling built on top of python and its ecosystem. It would be nice to see the ML community move on to something that's actually easily reproducible and buildable without "oh install this version of conda", "run pip install for this package", "edit this line in this python script".
Worked out fine in the end, though. Highly recommended if you're on an Nvidia rig: https://github.com/AbdBarho/stable-diffusion-webui-docker
