title: Can't initiate jupyter notebook
body: <p>I used to use ipython notebook before it was called Jupyter. However, when I tried to open that again (I have already updated all the ipython and python), the interface looks so weird like this <img src="https://i.stack.imgur.com/kwe0A.png" alt="enter image description here"></p>
  
  <p>I also tried to install jupyter following the instruction online but I can't initiate it at all. Any idea about how to fix it? <img src="https://i.stack.imgur.com/s0CR9.png" alt="enter image description here"></p>
