Hi,
We are making some improvements in our devel builds mechanisms in the following days.
And some of the enhancements involve testing the devel build upload, and those packages could be relatively broken.
So, please, use the latest release (0.7.1) as the cutting edge Bokeh.
When the work is complete, I will advice again about the availability of new devel builds.
Thanks for your patience!
Cheers.
Damian
