noise for the variance
itself. Useful for methods such as CycleDiffusion.   return_dict (bool, optional, defaults to True) —
Whether or not to return a ~schedulers.scheduling_ddim_inverse.DDIMInverseSchedulerOutput or
tuple.   Returns 
~schedulers.scheduling_ddim_inverse.DDIMInverseSchedulerOutput or tuple
  
If return_dict is True, ~schedulers.scheduling_ddim_inverse.DDIMInverseSchedulerOutput is
returned, otherwise a tuple is returned where t
