I'm curious about the conditioning of the control net

Hello. I’m studying Control Net among stable diffusers. I have a question.

  1. According to the thesis, if there are various conditions, you can just add them, but how do you add them?
  2. In addition, the paper says that it can be applied to various stable diffusion without learning, so I wonder how it can be applied to this part as well. I don’t know if it’s okay to have a control net weight based on stable diffusion A, and just put weight on the control net part of stable diffusion B.

I’d like to know the hugging face code or explanation regarding this.

Thank you.
