refactors pipelines inheriting from `StableDiffusionPipeline`

[yiyixuxu]

We have a couple of community pipelines that used StableDiffusionPipeline as the base class instead of DiffusionPipeline. Most of them are broken after we changed the signature of StableDiffusionPipeline. see more details on the issue here #6969 (comment)

pipelines should not use StableDiffusionPipeline as a base class. Is anyone interested in refactoring some of these community pipelines to inherit from DiffusionPipeline instead? You will need to:

1. update the base class to use DiffusionPipeline and any of the mixins needed e.g.

class CommunityPipeline(
    DiffusionPipeline, TextualInversionLoaderMixin, LoraLoaderMixin, IPAdapterMixin, FromSingleFileMixin
):

2. if the community pipeline use some of the methods in StableDiffusionPipeline - you need use #Copied from statement to copy over methods to your community pipeline. Learn more about the Copied from mechanism here https://huggingface.co/docs/diffusers/conceptual/contribution#copied-from-mechanism

Here is the list of pipelines that need to be refactored!

• Prompt2PromptPipeline(completed by @ihkap11 Prompt2Prompt: Inherit from DiffusionPipeline #7211 ): https://github.com/huggingface/diffusers/blob/main/examples/community/pipeline_prompt2prompt.py
• RegionalPromptingStableDiffusionPipeline (@pranjalks is working on it): https://github.com/huggingface/diffusers/blob/main/examples/community/regional_prompting_stable_diffusion.py
• StableDiffusionReferencePipeline ( completed by @StandardAI [Refactor] StableDiffusionReferencePipeline inheriting from DiffusionPipeline #7071)
• TensorRTStableDiffusionPipeline (@Bhavay-2001 is working on it): https://github.com/huggingface/diffusers/blob/main/examples/community/stable_diffusion_tensorrt_txt2img.py

Thank you for this opportunity! I would like to take StableDiffusionReferencePipeline.

hi @pranjalks
sure!
Just leave a message here about which ones you would like to work on:)

@StandardAI
thanks!

Hey, I have started working on RegionalPromptingStableDiffusionPipeline. Thank you!

@yiyixuxu I'll work on Prompt2Prompt pipeline. Thank you!

Hi @yiyixuxu, I would be happy to work TensorRTStableDiffusionPipeline.
Can you please assign it to me? Thanks

[yiyixuxu]

@Bhavay-2001 sure!
