ss labels for conditioning class-conditional consistency models. Not used if the model is
not class-conditional.   num_inference_steps (int, optional, defaults to 1) —
The number of denoising steps. More denoising steps usually lead to a higher quality image at the
expense of slower inference.   timesteps (List[int], optional) —
Custom timesteps to use for the denoising process. If not defined, equal spaced num_inference_steps
timesteps are use
