timesteps should be moved to. If None, the timesteps are not moved.   original_inference_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, thi
