  sem_guidance (List[torch.Tensor], optional) —
List of pre-generated guidance vectors to be applied at generation. Length of the list has to
correspond to num_inference_steps.   Returns 
SemanticStableDiffusionPipelineOutput or tuple
  
If return_dict is True,
SemanticStableDiffusionPipelineOutput is returned, otherwise a
tuple is returned where the first element is a list with the generated images and the second element
is a list of bools ind
