Why do you import UNet2DConditionModel from diffusers.models?

[ProKSMT]

In SDXL pipeline and SD1.5 pipeline, you import UNet2DConditionModel from diffusers.models other than from model.unet.

[Eugeoter]

The unet import of the diffusers pipeline is only used for code annotation. The actual loading of unet is done outside the pipeline. The ControlNeXt UNet is directly passed to the pipeline initialization.
