Matplotlib animation not working in IPython Notebook?

To animate a plot in matplotlib, we can take the following steps −

Set the figure size and adjust the padding between and around the subplots.
Create a random data of shape 10X10 dimension.
Create a figure and a set of subplots, using subplots() method.
Makes an animation by repeatedly calling a function *func*, using FuncAnimation() class.
To update the contour value in a function, we can define a method animate that can be used in FuncAnimation() class.
To display the figure, use show() method.

Example

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

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
data = np.random.randn(800).reshape(10, 10, 8)
fig, ax = plt.subplots()

def animate(i):
   ax.clear()
   ax.contourf(data[:, :, i])

ani = animation.FuncAnimation(fig, animate, 5, interval=50, blit=False)
plt.show()
