This looks newer than #2 and #11, though it seems similar.

Traceback (most recent call last):

I see this once in awhile, but not sure what triggers it. I'll try adding some debug output...

It looks like my code is older than HEAD. But I tried using pip to uninstall and reinstall, and I still have the same code. Is pip supposed to get more recent code?
Should I install some other way to get HEAD?
I reinstalled with:
$sudo pip3 uninstall pinggraph
$sudo pip3 install pinggraph
