Hey, sorry for the late response.
You are right that a repository like that is not available for Pumas right now. We are moving towards our Beta release and subsequently the 1.0 version, along with this the plan is to release a ton of tutorials and a translation of the DDMore model repository in Pumas, look out for announcements for that here. Meanwhile you can take a look at the existing tutorials (https://tutorials.pumas.ai) and maybe that can help you start getting your feet wet and experiment. We have some more tutorials ready that haven’t been added there but we would be happy to share if you had any specific requests.
Thank you
