Super weird. I think it is a cython bug, but I'm not sure. The problem seems to be that the parent class has the same method. I need to enforce the correct method by
self.foo(u) -> SparseGraph.foo(self, u) This seems to work (compiles and the doctests pass). jonatha...@googlemail.com schrieb am Freitag, 8.
