returns for a non-absent container.

(see L(here,https://github.com/docker/docker-py/issues/1310) for details).

|
For Python 2.6, C(docker-py) must be used. Otherwise, it is recommended to
|
|
install the C(docker) Python module. Note that both modules should I(not)
|
|
be installed at the same time. Also note that when both modules are installed
|
|
and one of them is uninstalled, the other might no longer function and a
|
|
reinstall of it is required."
