Python PyTorch 扩散器中的TypeError： getattr()： attribute name must be string，如何解决

我正在try 在我的Mac M1中使用Pytorch的漫射器来生成图片.我有一个简单的语法，如下所示:

modelid = "CompVis/stable-diffusion-v1-4"
device = "cuda"
pipe = StableDiffusionPipeline.from_pretrained(modelid, revision="fp16", torch_dtype=torch.float16, use_auth_token=auth_token) 
pipe.to(device) 

当我运行我的脚本时，它抛出一个错误，

(meta_ai) ➜  Difussion_Model /Users/urs/miniforge3/envs/meta_ai/bin/python "/Users/urs/Downloads/Difussion_Model/03_StableD

    load_method = getattr(class_obj, load_method_name)
TypeError: getattr(): attribute name must be string

在torch_dtype=torch.flat16中，我try 了这里提供的所有不同类型: https://pytorch.org/docs/stable/tensor_attributes.html个，但都不管用.

有谁能帮帮忙吗？

Updates on 6 Dec: 我复制并粘贴了专门用于M1的官方页面上的代码. https://huggingface.co/docs/diffusers/optimization/mps个 代码如下所示，

# make sure you're logged in with `huggingface-cli login`
from diffusers import StableDiffusionPipeline

pipe = StableDiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5")
pipe = pipe.to("mps")

# Recommended if your computer has < 64 GB of RAM
pipe.enable_attention_slicing()

prompt = "a photo of an astronaut riding a horse on mars"

# First-time "warmup" pass (see explanation above)
_ = pipe(prompt, num_inference_steps=1)

# Results match those from the CPU device after the warmup pass.
image = pipe(prompt).images[0]

但我仍然收到相同的错误:
