I ran the Model Comparision Example and found that there is an Attribute error when I run the last input. I checked multiple times.

What should be done here?
Sampler statistics, Diagnosing Biased Inference with Divergences, Posterior Predictive Checks - works without any problems.

Could you please upgrade pymc3 to master and run the example again? The `pm.compareplot` is recently updated.
