checking on ipyvolume seems off

[tacaswell]

It complains about 0.3.2 despite being installed.

The --no-deps is to prevent it from updating numpy to 1.13 via pip when conda installed numpy 1.12.

@tacaswell is there a downside to having pip replace numpy 1.12.1 from conda with numpy 1.13.1 from pypi?
