title: Eclipse: "Python not configured"
body: <p>Here is a screenshot of whats happening:</p>
  
  <p><img src="https://i.stack.imgur.com/tLse7.png" alt="Python not configured"></p>
  
  <p>Basically, I execute everything via command line but edit the source in eclipse.<br>
  This error prevents autocomplete which is annoying.</p>
  
  <p>I have gone to <code>window&gt;preferences&gt;PyDev&gt;Interpreter - Python</code> and set the correct values but they don't stay and even when I hit apply they don't seem to take for the current session.</p>
  
  <p>Any idea on what could cause this error message?</p>
