pylint: disabling R0921 does not work, still warning

I have a class which has two methods that raise `NotImplementedError` and also inherits from an abstract class (a class that contains abstract methods, from the `abc` package. This parent class in turn inherits from a class marked as abstract through `__metaclass__ = ABCMeta`). Due to this a R0921 warning is raised when running pylint on my code. If I remove the `NotImplementedErrors` pylint does not give that warning. Now, I've tried disabling the R0921 for the class like this: ``` # pylint: disable=R0921 class Wrapper(AbstractWrapper): ... def func(self, kwargs**): raise NotImplementedError ... ``` But it does not seem to work. I still get the warning "Abstract class not referenced". What am I missing?
