ARG002 is usually not raised in methods that immediately raise a NotImplementedError, but does if there is some other code in the method. However, EM101 enforces adding the error message into a separate variable, which is then seen as "code".

The result of this is that there is no way to write such a method without raising one or the other issue. See example below.

class EM101_found:
    def test_method(self, **kwargs):
        raise NotImplementedError("error message.")


class ARG002_found:
    def test_method(self, **kwargs):
        msg = "error message"
        raise NotImplementedError(msg)

running ruff check test_file.py --select ARG002 --select EM101 on the code snippet above results in

test_file.py:3:35: EM101 Exception must not use a string literal, assign to variable first
test_file.py:7:29: ARG002 Unused method argument: kwargs
