Fixes the missing numpy ones.
@jseabold this should still be backported to 0.6, looks innocent and obvious.
Can you do it? How do we do backporting right now? PR rebased against maintenance/0.5.x ?
Re: how to backport. See tools/backport_pr.py. You can use that to find (and apply locally) PRs that need to be backported. You can find them via the Milestone or the label as desired.
