Import error: Failed to import 'monasca_api.common.messaging.kafka_publisher'. Error: No module named kafka

[sanjana]

I have installed monasca-agent, monasca-common and monasca-api on my server running Ubuntu 16.04.
https://github.com/openstack/monasca-agent/blob/master/docs/Agent.md#instal
https://github.com/openstack/monasca-api
https://github.com/openstack/monasca-common

I have also installed influxdb and kafka on this server.

When i try to use the monasca-api command
Running the server in foreground mode
$ gunicorn -k eventlet --worker-connections=2000 --backlog=1000 --paste /etc/monasca/api-config.ini

I get the following output
