Note this leaves snips manager in an unusable state and it has to be restarted. This happens with any intent that doesn't have a slot at all. Other intents with slots are working.

Thanks for the issue !

Please, can you output the content of the /home/pi/.snips/intents/intents/play_music_intent.py file here :) ?

It seems like there is no __init__ method ... Which causes your problem ...

In your virtualenv // python installation, can you run a pip install snipsmanagercore --upgrade and make sure that version 0.1.7.0.0 is installed ?

[tschmidty69]

pi@raspberrypi:~ $ sudo pip install snipsmanagercore --upgrade
Requirement already up-to-date: snipsmanagercore in /usr/local/lib/python2.7/dist-packages/snipsmanagercore-0.1.7.0.0-py2.7.egg

Going to reinstall as apt, and give it a go, but it seems like the apt version is behind. Should we instead be pulling from pip or even github directly?

Hi, I'm in front of the same issue. Did you managed to succeed resolving it ? I also try to update managercore but i'm already on the last version...

76MPaul

Edit : In complement, this issue lead to the loss of the default output playback. This force to reboot the computer in order to get it worked again.

[anthonyray]

@tschmidty69 The apt version is lagging behind. Try to pull it from pip.

@76MPaul Can you try to launch snipsmanager as a foreground process (not in a daemon) and give us the backtrace ?

[76MPaul]

I was launching it as a foreground process and get exactly the same error as the first post. Then I discover that my used device from aplay -l move from subdevice 1/1 to subdevice 0/1 and I didn't get any sound from snips. But all my other soft worked...
