'import distributed' causes eating of bokeh server exceptions

See original GitHub issue

Not sure if this issue is better for here or for bokeh (pinging @bryevdv), but the simplest bokeh app I can think of does not print exceptions to the command line if I import distributed. The app looks like

from bokeh.io import curdoc
import distributed

def modify_doc(doc):
    raise ValueError
    return doc


doc = modify_doc(curdoc())

When you run this with bokeh serve <filename> and try to access the app, the exception does not get printed to the command line (as it should, and as it does when the distributed import does not occur).

This is still a major issue and makes debugging bokeh apps which use distributed or any library that imports it (e.g. xarray) really difficult. I’ll take a look at fixing this.

We handle interactive Python usage separately here:
