I am putting together a network latent space model, but can’t get it to sample in pymc3. I’m afraid I’m missing something obvious to do either with using theano transformations or shape parameters, but can’t figure out which. Here is the simplest version of the model that replicates the problem. N …

Yeah this is not very clear from the doc but passing step=... to pm.sample() inhibits the init=..., and as the default value of z is all 0 that’s the reason for Bad initial energy... error. The above code I posted with non-zero testval should works.

I can sample from the model actually - what error are you seeing?
