Build failed due to dependency conflict #352

TravisCI builds are failing due to version conflicts within alphalens' dependencies.

From Job #583155172:

PackagesNotFoundError: The following packages are not available from current channels:

  • pandas=0.19.2

Have in mind that version 0.19.2 of pandas was released in Dec 24, 2016.

From Job #583155169:

error: pandas 0.18.1 is installed but pandas>=0.19 is required by set(['statsmodels'])

Also have in mind that the version of statsmodels that is being referred above is 0.6.1 which was released in Dec 2, 2014.

So my suggestion would be bump alphalens' dependencies versions and have test if everything works as before.

Thanks for highlighting this - I've added this on our queue to prioritize. We should have working builds.
