Dear developers, I’ve noticed a problem that is most likely sampler related and was introduced with the upgrade to pymc3.1. This happens on sampling a hierarchical (two level) GLM. Description I observe that the sampler occasionally gets stuck in parameter space (not: temporal slowdown), exploring…
