@nchmura4 : My two comments regarding `self.assertEqual` and `self.assertFalse` should be applied to ALL places where you wrote that.  We're making a massive effort to remove function calls like this, so before this is merged, the diff should be checked to make sure that those (and any others) are not used.
@gfyoung got it, thanks for explaining
can you rebase
thanks, done.
can you rebase / update
@jreback - done. i updated all the version references, as well. let me know if you need me to do anything else.
https://circleci.com/gh/pandas-dev/pandas/4945#tests/containers/3

@jreback : Is this symptomatic of another `numpy` compatibility issue?
Merged in master to fix the Circle-CI build. Hopefully it passes this time.
Let us know when all the tests pass.
thanks @nchmura4
