ecommend to use solver_order=2 for guided
sampling, and solver_order=3 for unconditional sampling.


prediction_type (str, default epsilon, optional) —
prediction type of the scheduler function, one of epsilon (predicting the noise of the diffusion
process), sample (directly predicting the noisy sample) or v_prediction` (see section 2.4
