I made some syntactic sugar that makes the following possible in jupyter: It reloads the session with the new overrides and starts the pipeline. I can send you the code if you want.

%pipe tab_adult.ingest
for e1 in (0.3, 0.5, 0.9, 1.5):
    pipe("tab_adult.privbayes.synth", {"alg.e1": e1})

It also converts "alg.e1": e1 to {alg: {e1: e1}} for you
