Hi, I’m having problems with the find_MAP function with this simple model import pymc3 as pm import theano import numpy as np p_1 = 0.46 p_2 = 0.52 number_tosses = 1 heads = 1 with pm.Model() as ht_coin_flipping: coin = pm.Categorical('coin', p=[0.5, 0.5]) p = theano.shared(np.array([p_1,…

find_MAP is not really designed for models with only discrete unobserved variables. Newer versions of PyMC3 actually raise a ValueError if you use the default pm.find_MAP() in your model. You can trust the results of normal sampling and use those.
