Client API version error

[brollb]

when I run sudo courseraprogramming grade local my-custom-grader.v1.4 $(pwd)/tmp partId JoAlq with docker v1.9.1 (for both client and server), I get the following error:

ERROR:root:Could not set up the container to run the grade command in. Most likely, this means that you specified an inappropriate container id.
ERROR:root:Problem when running command. Sorry!

It looks like it is using version 1.8.0 of docker-py. When I roll back to 1.7.2, I no longer get this error. Also, if I use docker v1.10.3, I do not have any problems (though that version of docker is not currently supported for production on coursera).
