Hi Everyone, First of all, I am very happy to be part of the community here. A quick bio: I am a 25-year-old PhD student in Astrophysics at UCL in the United Kingdom. Love all things Data, and really looking forward to learning as much as possible about Bayesian stats and probabilistic programming …

That means you need to make sure biases_in_1 got the right shape, try: biases_in_1_raw = pm.Normal('b_in_1', shape = (n_grps, 1, n_hidden,))
