Dear Oisín,
Thank you for your detailed instructions. For a beginner like me, this is a
valuable guide to meander along. Nevertheless, Mnemosyne breaks still off
again. But this time with a different error message. Could it be because I
have an outdated version of Python (3.6)?
That I did:
1. ~$ pip3 --version
· pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)
2. ~$ pip3 install -U pip
