I've fixed the quality test in this branch:

I'm not sure how to contribute to this PR though.

Hi, as a note, the author of the pipeline discontinued support for the lpw pipelines in favor of using the most up to date core pipelines with the external library sd_embeds from the same author which is actively maintained.

Not sure it's worth to keep updating these pipelines, especially since there was some issues with some of the updates from the community.

@calmiLovesAI if you still want to merge the PR, just use the cli commands:

make style
make quality

Anyways, to pass the test, you just need to add the trailing comma to some of the clip_skip=clip_skip args you added that are missing it.
