@patrickvonplaten as diffusers become more stable and widely used, we need to make sure all updates are compatible at least with few past versions, to avoid any breaking changes and will avoid lots of issues which are emerging a lot due to incompatible updates.

Can we have some checks for this for all merged requests?

Thank you for fixing this so quickly, much appreciated!

I agree, the current mechanism of how we always fetch the community pipelines from "main" is suboptimal. I'll open a PR to instead use the current version of diffusers to fetch the community pipelines and then we could also maybe add a test folder where community contributors can add tests for their pipelines ? Wdyt @anton-l maybe we can run highly used community pipelines as nightly tests?

run highly used community pipelines as nightly tests

Thought about that too, added a reminder in #1679
