title: Error while training rasa core
body: <p>I am using <code>rasa nlu</code> and <code>rasa core</code>.</p>
  
  <p>I am trying out a restaurant example from <a href="https://github.com/RasaHQ/" rel="nofollow noreferrer">this <code>github</code> link</a>. I got stuck at the below step. The error log is not brief or I am not able to get any clue:</p>
  
  <p>The command that I am using is:</p>
  
  <pre><code>python -m rasa_core.train -s examples/restaurantbot/data/babi_stories.md 
    -d examples/restaurantbot/restaurant_domain.yml -o models/dialogue 
    --epochs 300**
  </code></pre>
  
  <p>What do you think is going wrong here?</p>
  
  <hr>
  
  <p>Command <code>pip show rasa_core</code></p>
  
  <pre><code>Name: rasa-core
