AttributeError: 'StableDiffusionPipeline' object has no attribute 'to'

when I try to excute the code:
from torch import autocast
from diffusers import StableDiffusionPipeline

pipe = StableDiffusionPipeline.from_pretrained(

prompt = “a photo of an astronaut riding a horse on mars”
with autocast(“cuda”):
image = pipe(prompt)[“sample”][0]“astronaut_rides_horse.png”)

It showed me that
AttributeError: ‘StableDiffusionPipeline’ object has no attribute ‘to’

‘pip install --upgrade diffusers’ is not worked

what should I do to solve this question? is it a version problem?

Might be a version problem?

The current release of diffusers (0.5.1) has had use_auth_token=True removed from all the examples, and for the most part doesn’t use autocast anymore either.

But definitely exists, so I’m not sure why it would tell you it doesn’t.
