Which python version do you support?
It requires Python 3.4.5 or above due to this issue:
https://github.com/mbevand/silentarmy/issues/8For those running Ubuntu 14.04 (which very unfortunately ships a slightly too old 3.4.x) there is a workaround documented in this github issue by n1koo (4th message from the top). I'll try to fix that in the next few days so SILENTARMY doesn't require Python 3.4.5.
