title: iPython autoreload magic function not found
body: <p>I have used the following scripts in an iPython notebook to enable autoreload.</p>
  
  <pre><code>import autoreload
  
  %autoreload
  </code></pre>
  
  <p>The import works find but the magic function throws the following error:</p>
  
  <pre><code>ERROR: Line magic function `%autoreload` not found.
  </code></pre>
  
  <p>Here are the current version settings as per the notebook 'about' section:</p>
  
  <pre><code>Python 2.7.3 (default, Jun 22 2015, 19:33:41) 
  [GCC 4.6.3]
  IPython 4.1.2 -- An enhanced Interactive Python.
  </code></pre>
  
  <p>Any pointers on what the issue could be would be appreciated.</p>
  
  <p>Thanks</p>
