Bug in pipeline_utils.py with different Python versions

[rebel-kblee]

Describe the bug

In Python versions less than 3.10, the default python typing package does not have the name attribute for formats like List and Tuple. As a result, an issue occurs in diffusers versions (>=0.32.2).

One way to solve this issue like #10762

Reproduction

from diffusers import ControlNetModel, StableDiffusionControlNetPipeline

controlnet = ControlNetModel.from_pretrained("hf-internal-testing/tiny-controlnet")
pipe = StableDiffusionControlNetPipeline.from_pretrained("hf-internal-testing/tiny-stable-diffusion-torch", controlnet=controlnet)
pipe.save_pretrained("sd_controlnet")

pipe = StableDiffusionControlNetPipeline.from_pretrained("sd_controlnet", controlnet=controlnet)

I think it's a wrong reproduce example, so I'll check again and reopen issue

I fix the reproduce example, so i'll reopen this issue

Thanks @rebel-kblee. This wasn't caught as it's an unusual case, we don't typically save a pipeline with a controlnet then want to use a different controlnet, we'd just the same pipeline with from_pretrained and pass a different controlnet. The fix may be duplicate of work done in #10758 can you test that?

Good. It works well. Thanks. @hlky
