title: 'PathCollection' object has no attribute 'do_3d_projection'
body: <p>I can't get output from the following code in python at Zeppelin:</p>
  <pre><code>import matplotlib.pyplot as plt
  from mpl_toolkits.mplot3d import Axes3D
  fig = plt.figure()
  ax = Axes3D(fig)
  
  x = list(range(0, 100))
  y = list(range(0, 100))
  z = list(range(0, 100))
  
  ax.scatter(x, y, z)
  plt.show()
  </code></pre>
  <p>And the error is:</p>
  <blockquote>
  <p>Fail to execute line 10: ax.scatter(x, y, z)</p>
  <p>AttributeError: 'PathCollection' object has no attribute 'do_3d_projection'</p>
  </blockquote>
  <p>In general, <code>scatter</code> does not work in python at Zeppelin and get the above error. Aslo, <a href="https://stackoverflow.com/q/37212257/3768871">this solution</a> does not work for me.</p>
