Horizon dashboard shows 500 error after installation of tacker

[simar]

The dashboard was working perfectly for me till the installation of tacker.

As I was installing tacker I came across tox -e config-gen which showed some errors

python.h missing fatal error which I removed after installing python 3.4 for some packages (libffi, python-dev)

after which tacker.conf was produced.

After successfully installing tacker I went to dashboard but I got error 500.

Attached are the apache2 error log
