 steps. More denoising steps usually lead to a higher quality image at the
expense of slower inference.   original_inference_steps (int, optional) —
The original number of inference steps use to generate a linearly-spaced timestep schedule, from which
we will draw num_inference_steps evenly spaced timesteps from as our final timestep schedule,
following the Skipping-Step method in the paper (see Section 4.3). If not set this will default to the
