title: OpenCV installation Google Colab
body: <p>I am trying to install OpenCV in google colab notebook.
  The official documentation says to do:</p>
  
  <pre><code>!apt-get -qq install -y libsm6 libxext6 &amp;&amp; pip install -q -U opencv-python
  import cv2
  </code></pre>
  
  <p>The first statement works fine and installs everything.
  But on importing cv2 I am getting an error saying:</p>
  
  <pre><code>ImportError: libSM.so.6: cannot open shared object file: No such file or directory
  </code></pre>
  
  <p>Any fix for this issue?
  Thanks for help!</p>
