La mia installazione di Python per OS X avviene tramite homebrew. Quindi aggiungo il software Python usando pip. Recentemente ho aggiornato matplotlib dalla versione 1.4.3 alla 2.1.0 tramite pip install matplotlib --upgrade , e ora matplotlib mi dà questo errore quando provo a fare una trama di base:
In [1]: plt.plot(np.arange(10))

Non sono sicuro di come diagnosticare questo. Tuttavia ho un Python 3 matplotlib funzionante.
Si tratta di un bug nella versione 2.1.0 di matplotlib?
