title: lmfit is installed but importing lmfit in python fails. Suggestions?
body: <p>I am trying to set up some software on Ubuntu 14.04 VM. It is python code that requires the lmfit package. I have run "pip install lmfit", which is successful, and running it again simply states that it is already installed:</p>
  
  <pre><code>kyle@kyle-VirtualBox:~/projects/MOSAIC$ pip install lmfit==0.7.4
  Requirement already satisfied (use --upgrade to upgrade): lmfit==0.7.4 in /home/kyle/.virtualenvs/MOSAIC/lib/python2.7/site-packages
  Cleaning up...
  </code></pre>
  
  <p>However, when I am using python, if I try to import lmfit, I get this error:  </p>
  
  <pre><code>&gt;&gt;&gt; import lmfit
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ImportError: No module named lmfit
  </code></pre>
  
  <p>Any suggestions for how to proceed? Why is the package not available within python?</p>
