I have the myapp.py file in http://docs.bokeh.org/en/latest/docs/user_guide/server.html
when i run the command, bokeh serve --show myapp.py, the web page http://localhost:5006/myapp keeps loading and says "waiting for localhost..." at the bottom left corner.
here is what I have on the terminal:
$ bokeh serve --show myapp.py
