Julia PyCall Bokeh in Jupyter Notebook

Question

Using Julia's PyCall to call Python's Bokeh running in a Jupyter notebook:

using PyCall

@pyimport numpy as np
@pyimport bokeh.plotting as plotting
@pyimport bokeh.io as io

io.output_notebook()

x = np.linspace(0, 4*np.pi, 100)
y = np.sin(x)

TOOLS = "pan,wheel_zoom,box_zoom,reset,box_select"

p1 = plotting.figure(title="Legend Example", tools=TOOLS)
p1[:circle](x,   y, legend="sin(x)")

io.show(p1)

Instead of getting a plot like in the Bokeh examples I get:

Out[1]: <Bokeh Notebook handle>

• Works fine in a Python 2/3 notebook.
• Using Docker/datascience-notebook base image.
