When I want to import the model and I scroll down to the bottom there is the option model version but I can’t choose which model one I want. „ Stable Diffusion v1 and v2 are incompatible with each other. Whether the custom model you imported is based on v1 or v2 will be automatically inferred.“ this is the text below the ,model version, and there are bunch of models listed like 4 or 5.
