Advanced: Deploy and run with cog (locally or cloud)

If you are not familiar with cog read: cog docs

Download Checkpoints and LoRa's from Cvitai and put in /models folder (a download_weights.py file to prepare everything with one file is a work in progress)

https://civitai.com/models/46422/juggernaut
https://civitai.com/models/82098?modelVersionId=87153
https://civitai.com/models/171159?modelVersionId=236130

predict with cog:

cog predict -i image="link-to-image"

Advanced: Run with A1111 webUI
