The loadnotebook() (from loader.py) relies on export_html from nbconvert which is not present with nbconvert 5.0.0.
It seams to have been moved to nbconvert.exporters.html.
Possible solution:
In loader.py change
from nbconvert import export_html
to
from nbconvert.exporters import html as export_html
