T2I Adapter - Segment
T2I Adapter is a network providing additional conditioning to stable diffusion. Each t2i checkpoint takes a different type of conditioning as input and is used with a specific base stable diffusion checkpoint.
This checkpoint provides conditioning on semantic segmentation for the stable diffusion 1.4 checkpoint.
