title: importing module in Spyder error
body: <p>I am trying to use sklearn in Spyder. At the beginning when I tried to import it I was gettingImportError: No module named sklearn</p>
  
  <p>Then I tied to set the PATH with PYTHONPATH manager and then use 'Update module names list' from tools menu.then restart the spydet but no success. </p>
  
  <p>at the end I copied the sklearn folder to <code>/Applications/Spyder.app/Contents/Resources/lib/python2.7</code></p>
  
  <p>This is how I find the PATH of sklearn and copied in into this folder :</p>
  
  <pre><code>&gt;&gt;&gt; import sklearn
  &gt;&gt;&gt; sklearn
  &lt;module 'sklearn' from '/Library/Python/2.7/site-packages/scikit_learn-0.12_git-py2.7-macosx-10.7-intel.egg/sklearn/__init__.pyc'&gt;
  &gt;&gt;&gt; 
  </code></pre>
  
  <p>and then I cd to the parent folder :</p>
  
  <pre><code>cp -r sklearn /Applications/Spyder.app/Contents/Resources/lib/python2.7
  </code></pre>
  
  <p>but when I try to import the sklearn to spyder like from <code>sklearn import dataset</code> :</p>
  
  <pre><code>Traceback (most recent call last):

  <p>any idea?Thanks</p>
