title: Do I need to uninstall Python 3.5 before installing Anaconda on OSX?
body: <p>I had some issues with matplotlib in virtualenvironments on Python and was recommended to uninstall 3.5 to install anaconda as a result. If so, do I need to <code>pip uninstall</code> everything (both globally and on my user) I see from <code>pip freeze</code> as well as everything I've installed with <code>brew</code>? Or will Anaconda be able to utilize what is already installed?</p>
