teps are not moved.   timesteps (List[int], optional) —
Custom timesteps used to support arbitrary spacing between timesteps. If None, then the default
timestep spacing strategy of equal spacing between timesteps is used. If timesteps is passed,
num_inference_steps must be None.    Sets the discrete timesteps used for the diffusion chain (to be run before inference).  step  < source > ( model_output: FloatTensor timestep: int sample: FloatTenso
