Google Auth working only once?

[JamieMax]

Hi Folks,

I've been through the guide with my lovely new Google AIY kit, and when I get to section 3.1 where I start the library demo app for the first time (src/assistant_library_demo.py), I get prompted to Auth, and it starts working...

The problem is that after a reboot I run the same command and I get a long traceback error, that I forgot to copy down... Does anyone have any ideas on what might be causing that? I appreciate any help - I'm new to python/linux, but trying my best.

This is what the dev terminal returns to me when I run the Code:

Code: Select all

Mmm - getting the same issue after ran test, got no answer, and button press caused a reboot. Any update or solution?
