I have the same issue after generating a Python client library with the docker image of swagger-codegen-cli swaggerapi/swagger-codegen-cli.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/swagger_client/__init__.py", line 19, in <module>

ImportError: No module named errorunknown

Is the issue probably fixed with #7684?
