Hi Thankyou for the info, I downgraded sqlalchemy accordingly, but there were lot of other dependencies I had to take care (as below). The error which still continues to persist in my environment is : RuntimeError: Unable to load quantum from configuration file /etc/neutron/api-paste.ini.
are there any other dependencies to be taken care to resolve this error? pip uninstall sqlalchemy (uninstalled -0.8.3) pip install sqlalchemy==0.7.9 pip install jsonrpclib pip uninstall eventlet (uninstalled -0.12.0) pip install eventlet (installed -0.14.0) pip install pyudev for the error Requirement.parse('amqp>=1.0.10,<1.1.0')) pip uninstall amqp pip install amqp -- but its installing 1.3.3 so, download the source code of 1.0.10 (https://pypi.python.org/pypi/amqp/1.0.10) python setup.py build python setup.py install Regards Gopi Krishna Yongsheng Gong gongysh at unitedstack.com VersionConflict: (SQLAlchemy 0.8.3 (/usr/lib64/python2.7/site-packages), Requirement.parse('SQLAlchemy>=0.7.8,<=0.7.99')) it seems your SQLAlchemy is newer than required. so pip uninstall sqlalchemy and then install older one: sudo pip install sqlalchemy==0.7.9 _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
