It is a cython version issue: https://github.com/cython/cython/issues/1955 It's supposed to be fixed though, so I don't know why you it isn't working for you. Are you sure that cython is installed in the same virtualenv as you're using to build numpy? If you were using a numpy sdist then it would make sense because we include the pre-generated .c files in the sdists instead of running cython, but given that you're building from a numpy checkout I dunno. -n -- Nathaniel J.
