  <li>Here is the full list of my anaconda environment information:<a href="https://i.stack.imgur.com/vZad1.png" rel="nofollow noreferrer">conda environment information</a></li>
  <li>and I am using Pycharm in Ubuntu 16.04:<a href="https://i.stack.imgur.com/CDOf8.png" rel="nofollow noreferrer">IDE</a></li>
  <li>Last but not least, I have tried to execute the code in the terminal but the error continued to exist, so I'm afraid that the problem is not concerned with the Pycharm IDE.<a href="https://i.stack.imgur.com/qCUCZ.png" rel="nofollow noreferrer">the problem is not concerned with IDE</a></li>

  <p>It will be appreciated if you could give me some suggestions.</p>
