Getting Parse Errors for alice chatbot with ros

edit

Hi,

I want to create a chatbot application and I came across this package for ROS. I cloned the repo into my workspace and have managed to get it working. There were a few changes that were needed in the launch files. Now, robot.launch files fires up the three nodes. However, i am getting the following list of errors:

/home/<username>/<workspace>/src/chatbot/scripts/ai.py:18: SyntaxWarning: The publisher should be created with an explicit keyword argument 'queue_size'. Please see http://wiki.ros.org/rospy/Overview/Publishers%20and%20Subscribers for more information.

[WARN] [WallTime: 1473135480.071641] Done initializing chatbot.

From this point both the terminals (with web.launch and robot.launch) are waiting for something. What would be the next step? Also how do I get rid of this parse errors?

Any help would be appreciated :)
