how to hide axes in matplotlib.pyplot

Question

I put the image in a numpy array, and draw it with the following code. How can I tell the program not to draw the axes, like (0, 100, 200...)

import matplotlib.pyplot as plt
plt.figure()
plt.imshow(output_ndarray)
plt.savefig(output_png)

You can also use...

plt.axis('off')

Answer 2

plt.xticks([])
plt.yticks([])
