I am getting following error:
Traceback (most recent call last):
File "/usr/bin/docker-compose", line 7, in
from compose.cli.main import main
File "/usr/lib/python2.7/site-packages/compose/cli/main.py", line 17, in
import docker
File "/usr/lib/python2.7/site-packages/docker/init.py", line 2, in

any ideas? Thanx
