title: Error while using Debug Console: DeprecationWarning: The `use_readline` parameter is deprecated and ignored since IPython 6.0
body: <p>I have an issue with the Pycharm Debug console. Here's what I do step by step: I set a breakpoint somewhere in my code and when it stops at this breakpoint, I open the debug console as described <a href="https://www.jetbrains.com/help/pycharm/using-debug-console.html" rel="nofollow noreferrer">here</a>. This is prompted:</p>
  <pre><code>&gt;&gt;&gt; 
  </code></pre>
  <p>Then I try to do something basic like <code>a = 1</code>, but I get

  <pre><code>Traceback (most recent call last):

  During handling of the above exception, another exception occurred:

  <p>When I start doing this for a whole new python file, everything works out well, but instead of the <code>&gt;&gt;&gt; </code> what is prompted is</p>
  <pre><code>In[2]: 
  </code></pre>
  <p>Where is the difference coming from and what can I do to use the debug console in the first case?</p>
