title: Python "statsmodels" not Importing When Using Rodeo IDE
body: <p>I installed Anaconda then Rodeo (using the setup file on their website). However, when I run a script I get the error below. The line with problems is:</p>
  
  <pre><code>import statsmodels.api as sm
  </code></pre>
  
  <p>Strangely this code does run perfectly using the Spyder2 IDE.</p>
  
  <p>Any suggestions?</p>
