title: google cloud compute engine change to python 3.6
body: <p>I am a running a python script where I train CNN on my laptop and now want to run it on google cloud. The script imports tensorflow and keras, for which I need Python 3.6</p>
  
  <p>The steps I followed were:</p>
  
  <ol>
  <li>Go to compute engine and create a virtual machine with 8cpus</li>
  <li>I ssh into the virtual machine, and I see that the python version is 2.7</li>
  </ol>
  
  <p>How can I change the python version to 3.6 so I can install keras, and then to be able to run my python script?</p>
  
  <p>Many thanks for your help</p>
