There was an attempt at making a port of numpy for .Net – but the company that started that, later stopped. I would suggest to test it outside Rhino, as Rhino uses IronPython and for now there is no IronPython version of numpy. You might be able to still load Enthought’s first attempt of the port in Rhino 5 32-bit, but you might also likely find some spot that will possibly never be implemented.
