title: Why is "import gym" grayed out in pyCharm and I can´t import it?
body: <p>I´m trying to run some basic Pytorch gym code (Lunar Lander) in Pycharm, using a Mac. In the tutorial I see &quot;import gym&quot; as the first line. However, when I type this on Pycharm it grays out.
  I tried <code>pip install gym</code> and <code>pip install --upgrade pip</code> just in case.
  I tried to use Jupyter but it didn´t work for gym modules.</p>
