I have two Bionic x86_64 systems. One was showing the problem, the other was not.
The problem disappeared after issuing:

# apt purge python-backports.functools-lru-cache
# apt install python-matplotlib

The first command also uninstalled python-matplotlib.
The second command re-installed python-backports.functools-lru-cache and _created_ the file /usr/lib/python2.7/dist-packages/backports/__init__.py

The two systems were installed at different times and are updated at different times as well; maybe this problem only appeared for a short time, and was later solved. (I am trying to make sense of @stefanor 's comment)
