ference_steps (int, optional) —
The original number of inference steps, which will be used to generate a linearly-spaced timestep
schedule (which is different from the standard diffusers implementation). We will then take
num_inference_steps timesteps from this schedule, evenly spaced in terms of indices, and use that as
our final timestep schedule. If not set, this will default to the original_inference_steps attribute.   timesteps (List[int],
