lement is a list with the generated images
  Function invoked when calling the pipeline for generation.  Examples:   Copied >>> import torch
>>> from diffusers import PixArtAlphaPipeline

>>> # You can replace the checkpoint id with "PixArt-alpha/PixArt-XL-2-512x512" too.
>>> pipe = PixArtAlphaPipeline.from_pretrained("PixArt-alpha/PixArt-XL-2-1024-MS", torch_dtype=torch.float16)
>>> # Enable memory optimizations.
>>> pipe.enable_model_cpu_offl
