how to hide axes in matplotlib.pyplot
<p>I put the image in a <code>numpy</code> array, and draw it with the following code. How can I tell the program not to draw the axes, like <code>(0, 100, 200...)</code>    </p>

<pre><code>import matplotlib.pyplot as plt
plt.figure()
plt.imshow(output_ndarray)
plt.savefig(output_png)
</code></pre>
