Issue running taxis example notebook

[DABH]

I'm trying to run the taxi example notebook and am hitting an error on the first import import beaver_sdk I see that beaver_sdk isn't referenced in requirements.txt -- should it be?

I tried to import the module locally via

import sys
sys.path.append('../../')

(and some variants, like appending beaver_sdk), but then the cell says that that package has no classes in it, which is odd.

Any ideas on the right way to import and get things up and running?
