A random number generator.   return_dict (bool, optional, defaults to True) —
Whether or not to return a SdeVeOutput or tuple.   Returns 
SdeVeOutput or tuple
  
If return_dict is True, SdeVeOutput is returned, otherwise a tuple
is returned where the first element is the sample tensor.
  Predict the sample from the previous timestep by reversing the SDE. This function propagates the diffusion
