About code problem when running smtrain.py

 I want to do more research on the basis of your idea and I have download source code provided from github(https://github.com/Mid-Push/Moving-Semantic-Transfer-Network). However, I have encountered some difficulties in the process of reviewing your system. For example, we encounter some problems as follows when running smtrain.py:

During handling of the above exception, another exception occurred:

I don't know if I missed something? Please give me some advice.
Thank you very much for your favor.
