Pycharm cannot find installed packages: keras
<p>I installed pycharm-2016.1.4 in my PC running Ubuntu 14.04. I have installed keras (a python package) using <code>pip install keras</code> and pycharm <strong>can</strong> find it <strong>before</strong>. But it <strong>cannot</strong> find keras <strong>now</strong>. I do not modify any settings, so this problem may be wired. My python version is python2.7.

<p>I use <code>pip list</code> to verify that I have keras installed:</p>

<p>But check this package in pycharm by using: Settings -> Project -> Project Interpreter. Keras is <strong>NOT</strong> in package list (The interpreter used is the same as the result of <code>which python</code> in terminal).</p>

<p>Any suggestions are welcome. Thank you.</p>

<p>I do not know what happened, but the problem solved with the following steps.</p>

<ol>
<li>Uninstall old keras </li>
<li>Re-install keras: <code>pip install keras</code></li>
</ol>

<p>Then I can <code>import keras</code> in pycharm.</p>

<p><strong>NOTE:</strong> It is strange since I have keras installed but cannot find it in <strong>Project Interpreter's package list</strong>.</p>
