title: Import Openpyxl on Python 2 or Python 3
body: <p>I have the following codes running fine in Python 3. But I got an error of "no module named openpyxl" when i run in Python 2. </p>
  
  <pre><code>import openpyxl
  from openpyxl import Workbook
  </code></pre>
  
  <p>I did try "pip install openpyxl", and "!pip install openpyxl" in Python 2 in Bluemix but still not working. Any advice? Thank you so much!!!!!!</p>
