eOutput is returned, otherwise a tuple is
returned where the first element is a list with the generated images.
   Examples:   Copied >>> import torch

>>> from diffusers import ConsistencyModelPipeline

>>> device = "cuda"
>>> # Load the cd_imagenet64_l2 checkpoint.
>>> model_id_or_path = "openai/diffusers-cd_imagenet64_l2"
>>> pipe = ConsistencyModelPipeline.from_pretrained(model_id_or_path, torch_dtype=torch.float16)
>>> pipe.to(device)
