Я пытаюсь импортировать matplotlib.animation, но он показывает с именемprocesserror

Я запускаю это в блокноте jupyter. 

 import numpy as np
 import pandas as pd
 import matplotlib.pyplot as plt
 import matplotlib.animation as animation

 %matplotlib inline

Я пытался запустить его как файл .py, но я получаю ту же ошибку.

Я получаю следующую ошибку :
