@Rocketknight1 this might help with keeping track to everything.
I'm going to start working on the 2nd issue above hope I fix it soon.

@amyeroberts just for clarification.

• the second issue is all about when a repo has a custom pipeline and then (let's say for example you finetune the model and push the new model to another repo) the custom pipeline breaks down when loaded from the final repo.
• the push_to_hub method to pipelines is self explanatory, I have reread this for some time now, and I think I am beginning to understand where they're coming from coz the pipelines library is built on top of a model, and again I agree that that should be put for another day since it is irrelevant for now, allowing people to easily push their pipelines takes priority for now.

apologies for failing to notice most of the stuff (i made some some wrong assumptions about the {repo_id}--{module} tag and it mislead both me and the maintainers at the beginning), so i wanted to give you a clarified update for what i came out with hope this helps you out
