title: Module not found error in PyCharm, but it is installed as an Anaconda package
body: <p>I have installed <a href="https://en.wikipedia.org/wiki/Anaconda_(Python_distribution)" rel="nofollow noreferrer">Anaconda</a> 3 and <a href="https://en.wikipedia.org/wiki/JetBrains#IDEs" rel="nofollow noreferrer">PyCharm Community Edition</a> after that. I am able to chose the interpreter to be a <a href="https://en.wikipedia.org/wiki/Conda_(package_manager)" rel="nofollow noreferrer">Conda</a> environment. But when I try using certain packages, such as <a href="https://en.wikipedia.org/wiki/Matplotlib" rel="nofollow noreferrer">Matplotlib</a>, it throws &quot;Module not found error&quot;. When I run pip, it returns saying that matplotlib <em>is</em> available.</p>
  <pre class="lang-none prettyprint-override"><code>pip install matplotlib
  Requirement already satisfied: matplotlib in./anaconda3/lib/python3.6/site-packages
  </code></pre>
  <p>Clearly the package is there and for some reason it does not show up.</p>
