Answer 1

I expect you all are hitting this recent issue:

Bokeh Server is incompatible with tornado=4.5

Tornado 4.5 (released a few days ago) made a change that caused the Bokeh server to no longer function properly. A fix for this is in master and will be in the next 0.12.6 release. But the fix is also available in the latest dev builds. Your immediate options are:

• downgrade Tornado to <= 4.4.2, or
• install the Bokeh >= 0.12.6
