Hi, I have written the code and added the relevant tests and ran them, they failed in 3 cases, attached below, I'll need some assistance to test the code using images as I am GPU poor

Could you fix the quality tests using make quality? Could you also add this pipeline to the PAG docs: https://github.com/huggingface/diffusers/blob/main/docs/source/en/api/pipelines/pag.md

I was able to get this code running on Colab, this is how the outputs look:

I think CI still not passing
can you run make style?

I've ran it and made the change, hopefully it passes now

[yiyixuxu]

is this a merge conflict? can yo uadd this line back?

[yiyixuxu]

also need to add pag sd inpaint here too -currently CI fail for some import error

[darshil0805]

done

I'm still seeing an import error https://github.com/huggingface/diffusers/actions/runs/11266431877/job/31368980510?pr=9386#step:5:250

Not sure why there is an import error, I'm able to test the script through Colab

[hlky]

make fix-copies (after suggested change) should resolve the dependency issue
