question related to fix issues of merge_artifacts I understand merge_artifacts doesn't work perfectly. It sometimes can't merge a property even it's not modified. but I don't want to do

self.a = inputs[0].a

because there are lots of these attributes I want to set. and the code just get tedious. what's a good alternative way here?

@hundreds-motorcycle-57551 - are you interested in just extracting artifacts from the first task? depending on your use case, we can help with an example.

yes, I am. There are a lot of artifacts (small attributes) I would like to collect from the first task (actually all tasks share the mostly same attributes). an example would be really appreciated.

something like this -

first = inputs[0]
    self.first_input_attrs = {k: getattr(first, k) for k in first._datastore}
