ample.   generator (torch.Generator, optional) —
A random number generator.   return_dict (bool) —
Whether or not to return a EulerDiscreteSchedulerOutput or
tuple.   Returns 
EulerDiscreteSchedulerOutput or tuple
  
If return_dict is True, EulerDiscreteSchedulerOutput 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 propa
