How use push_session(io_loop=myloop) & myloop.start() instead of session.loop_unitl_closed() ?

Hello

I tried to use push_session(io_loop=myloop) & myloop.start() in my code.

Here the code:

import tornado.ioloop

from bokeh.client import push_session

from bokeh.plotting import curdoc

import functools

def main(top_block_cls=top_block, options=None) :

try:

doc= curdoc()

doc.title=“Top Block”

push_session(doc, session_id=“top_block”, url=“http://localhost:” + port + “/slide”, app_path=None, io_loop= myloop)

tb = top_block_cls(doc)

try:

tb.start()

myloop.start()

finally:

print “OK”

finally:

print "OK’

But when I try to run the script I have the following error:

NameError: global name ‘myloop’ is not defined

How use correctly push_session & myloop.start() ?

Thanks
