interact() fails with "output_notebook is not defined"

interact() fails with NameError: name ‘output_notebook’ is not defined

This is a fresh installation of jupyter, lightkurve, and bokeh via pip using python 3.6 today.

Explicitly specifying from bokeh.plotting import * (or import outpute_notebook) does not resolve the issue.

`import lightkurve

from lightkurve import KeplerTargetPixelFile

tpf = KeplerTargetPixelFile(“ktwo246199087-c19_lpd-targ.fits”)

tpf.interact()

@gully Would you be willing to investigate?

Will do! I suspect the answer is in our optional handling of bokeh dependencies.
