handle case when controlnet is list or tuple

[noskill]

In StableDiffusionControlNetPipeline constructor controlnet has type Union[ControlNetModel, List[ControlNetModel], Tuple[ControlNetModel], MultiControlNetModel] so such case should throw an exception

Hey @noskill,

Could you please add a reproducible code snippet that shows the current error ?

[noskill]

@patrickvonplaten minimal example:

from diffusers import ControlNetModel, StableDiffusionControlNetPipeline


model_id = "realismEngine/realismEngine_v10.safetensors"
cnet_id = "DionTimmer/controlnet_qrcode-control_v1p_sd15"

cnets = [ControlNetModel.from_pretrained(cnet_id)]
StableDiffusionControlNetPipeline.from_single_file(model_id, controlnet=cnets)

I see! Indeed that's a very nice fix - thank you :-)
