diffusion process.   eta (float) —
A stochastic parameter (referred to as gamma in the paper) used to control the stochasticity in every step.
When eta = 0, it represents deterministic sampling, whereas eta = 1 indicates full stochastic sampling.   generator (torch.Generator, optional) —
A random number generator.   return_dict (bool, optional, defaults to True) —
Whether or not to return a TCDSchedulerOutput or tuple.   Returns
