Code execution takes too much time #371

Hello, I am trying to execute from Ch2_MorePyMC_PyMC3:

# To be explained in Chapter 3!
with model:
    step = pm.Metropolis(vars=[p])
    trace = pm.sample(40000, step=step)
    burned_trace = trace[15000:]

for the section with cheating detection. But it shows that sampling will take over 20 mins(!) to execute

My PyMC3 version is 3.2
