title: ipykernel (Jupyter notebook/labs) cannot import name ''filefind" from traitlets.utils
body: <p>I installed Jupyter notebook and labs on and EC2 instance and for some reason I get the following error:</p>
  <blockquote>
  <p>ImportError: cannot import name 'filefind' from 'traitlets.utils' (/usr/lib/python3/dist-packages/traitlets/utils/<strong>init</strong>.py)</p>
