Question about Bokeh server not generating graph

Hi,
So I just installed bokeh 0.9.2 on Debian8, and I got bokeh-server remotely up and running. I tried some example files to generate graphs. The server page shows the generated document, but it doesn’t generate the graph when I click on it. The log shows 200, but I couldn’t see the graph on the page of my local PC. Currently I do not have multi user feature, but I’m using the default user. Also, the example I used is as follows: (The IP address is replaced with *)

from bokeh.plotting import figure, output_server, show, push

from bokeh.session import Session

session = Session(root_url=‘http://********:5006/’, load_from_config=False)

output_server(“test.html”, url=‘http://********:5006/’, session=session)

p = figure()

p.line([1, 2, 3, 4, 5], [6, 7, 2, 4, 5], line_width=2)

push()

I’m not sure if this is a problem with lack of some packages or it’s on the bokeh server, would someone help me with that? Thanks!

Ben
