Docker-py: AttributeError: 'SocketIO' object has no attribute 'raw'

[graingert]

As raised in https://github.com/docker/compose/issues/5353 but I think it's actually a docker-py issue:
docker-composeup redis
Creating procensus_redis_1 ...
Creating procensus_redis_1

ERROR: for procensus_redis_1 'SocketIO' object has no attribute 'raw'

ERROR: for redis 'SocketIO' object has no attribute 'raw'

If I put a debugger here, I can see that:

I suspect the bug was introduced here: https://github.com/docker/docker-py/commit/1359eb1100d602c5115c07175724002d30a042ee

[graingert]

Function at fault https://github.com/docker/docker-py/blob/f238fe5554cca48bb9bb366a07bd219c090e445b/docker/api/client.py#L271-L280

Thanks for the report. Can you specify:

• what version of Python you're working with
• which OS you're running on
• which method you use to connect to the engine (Unix socket, https, named pipe?)

Thank you

[graingert]

I'm using python 3.6 connecting via 'http+docker://localunixsocket' on Ubuntu 17.10

Thanks! Python 3.6 is recurrent in the other reports as well. I'll look into it asap.

Same error message but on Python 3.4, Ubuntu 14.04, http+docker://localunixsocket here.

I've also seen this with python 3.4 on Ubuntu 14.04, connected...however calls to 'exec_run' connect.

Came up in an automated build on travis.

2.6.1 is now on PyPi. Thank you for the detailed reports and sorry about that!
