title: iPython notebook not working in Pycharm
body: <p>I did exactly as <a href="https://confluence.jetbrains.com/display/PYH/Using+IPython+Notebook+with+PyCharm" rel="noreferrer">the official guide</a> told.</p>
  
  <p>For me I didn't have this window pop up when I click the <code>Run</code> button<a href="https://i.stack.imgur.com/4lIf1.png" rel="noreferrer"><img src="https://i.stack.imgur.com/4lIf1.png" alt="enter image description here"></a></p>
  
  <p>However, when I click the <code>Run</code> button it was just not working and showed a <code>*</code> in the bracket.
