[afourney]

This error will occur when you try to use docker, but don't have the docker python library installed. Try:

pip install docker

And let us know if you still run in to this problem.

[whatactuallyis]

when "use_docker": False, the code runs, but when running as "use_docker": "python:3" or True, I get the same error.

[mattwilliamson]

Same here on Ubuntu

[ekzhu]

This error looks like your docker library is not installed but set user_docker = True.
