title: Image is not displaying in Google Colab while using imshow()
body: <p>I am working on a project which requires functions from OpenCV to plot images.
  I am trying to display image using the below code in Google Colab. But nothing shows up in the output. Can anybody help me with this?</p>
  <pre><code>%pylab notebook
  import cv2
  
  testim = imread('butterfly.jpg')
  figure()
  imshow(testim)
  plt.show()
  </code></pre>
