title: How to install/run Jupyter in Ubuntu 15.10?
body: <p>I already have python3/ipython3 (and notebook) installed. So I <a href="http://jupyter.readthedocs.org/en/latest/install.html" rel="noreferrer">followed the instructions</a>, and I did:</p>
  
  <pre><code>$ pip3 install jupyter
  </code></pre>
  
  <p>And it seems to have succeeded. But at nothing seems installed (at least not in my PATH):</p>
  
  <pre><code>$ jupyter
  jupyter: command not found
  
  $ python3 jupyter
  python3: can't open file 'jupyter': [Errno 2] No such file or directory
  
  $ ipython3 jupyter
  [TerminalIPythonApp] WARNING | File not found: 'jupyter'
  
  $ ipython jupyter
  [TerminalIPythonApp] WARNING | File not found: u'jupyter'
  </code></pre>
  
  <p>Sorry, I'm a noob when it comes to the python installation details, I'm certainly missing something obvious, but I can't find it in the docs.</p>
  
  <p>Any help would be much appreciated!! :)</p>
