Trying to run the same simple model with version 0.2.1, I get the error below.

m = PMProphet(df_city, name='model')

# Fit the model (using NUTS)
m.fit(method='NUTS')

I see, you changed the signature for fit from 0.2.0 which broke the example code I had.

It's now 

m.fit(method=Sampler.NUTS)

exactly, I wanted to make sure people were using the right samplers.
