 process. If True,
the sigmas are determined according to a sequence of noise levels {σi}.   prediction_type (str, defaults to epsilon, optional) —
Prediction type of the scheduler function; can be epsilon (predicts the noise of the diffusion process),
sample (directly predicts the noisy sample) or v_prediction` (see section 2.4 of Imagen
Video paper).   timestep_spacing (str, defaults to "linspace") —
