Cython does have a plugin for gdb https://cython.readthedocs.io/en/latest/src/userguide/debugging.html https://cython.readthedocs.io/en/latest/src/userguide/debugg... however I have not used it. Generally I don't like writing cython code directly however and rather start with working python code and add types etc., cython -a really helps in those situations.
