[Numpy-discussion] building numpy with python3.7

OK, thanks for the link to the issue. I'm not using virtual environments - I built python3.7 (and 2.7) with the `make altinstall` method. I managed to get the numpy build working on 3.7 by removing the
`random/mtrand/mtrand.c` file so that it gets (re-)generated during the build using the latest cython version.
Thanks for the help!

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.
