I saw success by running: pip uninstall docker docker-py

Then re-running our ansible scripts.

[jwmatthews]

I think this issue is now resolved with the above workaround if the older docker-py was installed.

Please re-open otherwise.

[jwmatthews]

Note, I saw this again, but I was on ansible-2.2

Once I upgraded to ansible 2.3.0 issue was resolved.
