Comment 4 for bug 1621403

I had the same problem before, In my case it was that I didn't have python-barbicanclient installed. It fails to import it and is not able to load lbaas panel.

If you copied 1481 file and it's not able to load panel you can do the following to determine the cause:
python manage.py shell
>>from neutron_lbaas_dashboard.dashboards.project.ngloadbalancersv2 import panel
It should tell you why it's not able to load
