python 2.7 functools_lru_cache does not import although installed

Question

When I try to import matplotlib I get an error

Traceback (most recent call last):

Also meet this issue on Ubuntu 16. Uninstall & reinstall not work for me.

My solution is reinstall from apt.

pip uninstall matplotlib
sudo apt-get autoremove python-matplotlib
sudo apt-get install python-matplotlib
