If you are using pymata-iot and are now seeing these exceptions:

/usr/bin/python3.5 /home/afy/PycharmProjects/pymata_aio/pymata_aio/pymata_iot.py

Traceback (most recent call last):

You will need to manually install pytrie with:

pip install pytrie.

I submitted an issue with Autobahn and hopefully they will fix the issue and install pytrie automatically from a pip install.
