title: ERROR: Line magic function `%matplotlib` not found
body: <p>I have just installed IPython on a Mac (MacOS 10.7.5) following the instructions for anaconda on <a href="http://ipython.org/install.html" rel="nofollow noreferrer">http://ipython.org/install.html</a>, with no obvious errors. I now want to work my way through the example notebooks. In notebook &quot;Part 1 - Running Code&quot;, everything works as it should until I get to</p>
  <pre><code>%matplotlib inline
  </code></pre>
  <p>Then I get the error message</p>
  <blockquote>
  <p>ERROR: Line magic function <code>%matplotlib</code> not found.</p>
  </blockquote>
  <p>Everything after that works, except that plots, instead of appearing inline, pop up in a new window.</p>
