Mit dem folgenden Code wird ein TclError generiert.

import matplotlib
matplotlib.use('TkAgg')
import matplotlib.pyplot as plt

plt.plot([1,2,3,4], [1,4,9,16], 'ro')
plt.axis([0, 6, 0, 20])
plt.show()

Wenn ich mein Skript im Terminal ausführe, erhalte ich Folgendes:

Was verursacht diesen Fehler? Ich habe versucht, @ hinzuzufügbackend: TkAgg zu meinemmatplotlibrc Datei, ohne Erfolg.

Bitte berate
