Huggingface space does not work. Nor Docker image

1. Docker image does not work. Gives me this error: https://pastebin.com/kE6TLYju . Seems like the repo is just broken. Could you please fix it?
2. Is it a tool for making a proper inference of SD 1.5 in 1 step or it's just a model different from SD 1.5 which is able to generate images in 1 step? Did not get this from your GitHub
