Not a big deal, but Ubuntu 16.04 Python 2.7 0 does not like the spaces in the names.
Just replace the spaces with a - and all works well.
Example:
name='the-context-text
name='the-answer-text-up-to-the-current-token
Do all the names that way.

Question: Does the bot auto-learn from conversation or must it be retrained with each session ?
