title: Import python file from terminal
body: <p>I am trying to run a python file from my terminal. So when I run it I get the error below: </p>
  
  <pre><code>Traceback (most recent call last):
  File "evaluate_classifier.py", line 1, in &lt;module&gt;
  import alarm_detection.classifier_selection.classifier_evaluation as clf_eval
  ImportError: No module named alarm_detection.classifier_selection.classifier_evaluation
  </code></pre>
  
  <p>In my file I use this code:</p>
  
  <pre><code>import alarm_detection.classifier_selection.classifier_evaluation as clf_eval
  </code></pre>
  
  <p>How can I import the python file classifier_evaluation from terminal (it is in a different directory)</p>
  
  <p>Thanks.</p>
