unet (UNet2DModel) —
A UNet2DModel to denoise the encoded image.   scheduler (SchedulerMixin) —
A scheduler to be used in combination with unet to denoise the encoded image latens. Can be one of
DDIMScheduler, LMSDiscreteScheduler, EulerDiscreteScheduler,
EulerAncestralDiscreteScheduler, DPMSolverMultistepScheduler, or PNDMScheduler.    A pipeline for image super-resolution using latent diffusion. This model inherits from DiffusionPipeline. Che
