The recommended install version (according to the README) is >=2.0.dev, however the docs have not been updated to reflect some breaking changes. Specifically http://docs.graphene-python.org/projects/django/en/latest/tutorial-plain/ still uses: ```python def resolve_category(self, args, context, info): ``` This should be changed to ```python def resolve_category(self, info, **args): ``` I would be glad to put a pull request in for this issue.
