title: Plotly in Jupyter issue
body: <p>I installed plotly.py to work some plots using Jupyter but I cannot import it.</p>
  
  <pre><code>! pip install plotly --upgrade
  Requirement already up-to-date: plotly in c:\python34\lib\site-packages
  Requirement already up-to-date: requests in c:\python34\lib\site-packages (from plotly)
  Requirement already up-to-date: six in c:\python34\lib\site-packages (from plotly)
  Requirement already up-to-date: pytz in c:\python34\lib\site-packages (from plotly)
  Cleaning up...
  </code></pre>
  
  <p>and then </p>
  
  <pre><code>  import plotly
    ---------------------------------------------------------------------------
  ImportError                               Traceback (most recent call last)
  &lt;ipython-input-6-c27a4132ad2e&gt; in &lt;module&gt;()
  ----&gt; 1 import plotly
  
    ImportError: No module named 'plotly'
  </code></pre>
  
  <p>I'm running Python 3.4.1, so as Jupyter, and the thing that I cannot get is that plotly works just fine when I'm running Python from the command line. Any suggestions? (I really don't want to clean install Python)</p>
