  <p>Why are these messages showing up...even though I have the proper versions installed??I have upgraded and reinstalled them over and over. I also reinstalled pip and also tried easy install for pip. But the problem persists.</p>
  
  <p>Could something be wrong with my OS installation? (Ubuntu 16.4)</p>
  
  <p>These are some results I got by running 
  <code>pip freeze</code></p>
  
  <pre><code>tensorboard==1.8.0 
  tensorflow==1.8.0 
  numpy==1.14.3 
  html5lib==0.9999999 
  httplib2==0.9.1
