I’ve been using a deterministic to save the prediction of my model, i.e.
p1 = pm.Normal("p1", mu=0., sd=1.) p2 = pm.Normal("p2", mu=0., sd=1.) mu = pm.Deterministic("mu_", p1+p2))
It appeared that https://github.com/pymc-devs/pymc3/pull/1215 introduced the convention to hide variables with trailing underscores, but that doesn’t work for me in the example above. The transformed variables are hidden, but the deterministic that I defined with a trailing underscore appears nonetheless.
