tuple. When returning a tuple, the first element is a list with the generated images.
  Function invoked when calling the pipeline for generation.  Examples:   Copied >>> import torch
>>> from diffusers import StableDiffusionXLPipeline

>>> pipe = StableDiffusionXLPipeline.from_pretrained(
...     "stabilityai/stable-diffusion-xl-base-1.0", torch_dtype=torch.float16
... )
>>> pipe = pipe.to("cuda")
