I have a hierarchical time-varying weibull survival model with a model structure based off of this pymc3 example It works fine for pymc3 (3.11.5), but it ends up with 100% divergences in pymc v4 (4.1.4). When I look at the posterior, every draw within chains is identical (i.e. for all i, 0:1000, t…
