Docker script docker-compose --version is now throwing a weird error and is complaining about a missing python module ordered_dict. Not sure why is this happening but previously it was working just fine. Not sure if its related but I installed pip for python and later installed awscli using the pip.

Below is the stack trace I get on running docker-compose --version

Traceback (most recent call last):

Reinstalling docker-compose did the trick for me. You can reinstall by deleting the docker-compose file from /usr/local/bin and installing it again using instructions provided here.
