  panel/examples/apps/django2/ example doesn't work
  The django2 example doesn't work at least for Django 2.2. The interactive plot doesn't show up and there are no clear error messages either. However, the same example provided by ParamBokeh works fine. But I prefer Panel if this problem can be solved.
