title: How to upgrade scikit-learn package in anaconda
body: <p>I am trying to upgrade package of scikit-learn from 0.16 to 0.17. For that I am trying to use binaries from this website: <a href="http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn" rel="noreferrer">http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn</a>. I have Windows 7 x64 bit. I downloaded the relevant package locally and gave following commands and got Requirement already up-to-date:</p>
  
  <pre><code>C:\Users\skumar&gt;pip install --upgrade --use-wheel --no-index --find-links=../../
  SOURCE/APPS scikit-learn
  Ignoring indexes: https://pypi.python.org/simple
  Requirement already up-to-date: scikit-learn in c:\anaconda3\lib\site-packages
  </code></pre>
  
  <p>Then I tried to upgrade it from remote site and got similar result:</p>
  
  <pre><code>C:\Users\skumar&gt;pip install --upgrade --use-wheel --no-index --trusted-host www.
  lfd.uci.edu --find-links=http://www.lfd.uci.edu/~gohlke/pythonlibs/ scikit-learn
  
  Ignoring indexes: https://pypi.python.org/simple
  Requirement already up-to-date: scikit-learn in c:\anaconda3\lib\site-packages
  </code></pre>
  
  <p>On Remote site there are two versions i.e., 0.16 &amp; 0.17. Is there a way to specify version in command? Or how do you install/upgrade wheel file?</p>
