1) Install CPython for AMD64 archĭownload a 64 bit MSI installer file from. These instructions are valid only for Python installed with an official CPython installer, obtained from. The following steps show a very simple way to get NumPy binaries for the AMD64 architecture installed on top of CPython 3(.4). It is up to you to understand the license impacts and whether you want or can use these builds. Nevertheless, in many cases a working solution are the non-official builds provided by Christoph Gohlke, created with Intel’s commercial compiler suite. One of the reasons is that there is no adequate (open source, reliable, feature-rich) tool chain for creating proper 64 bit builds of NumPy on Windows (further references: numpy mailing list thread, Intel forums). So, if you are serious about your project, you need to either consider building on top of Unix-like platforms and inherit external quality assurance, or (on Windows) you need to anticipate issues of various kinds, and do extensive testing on your own. In fact, 64 bit Windows is not officially supported by NumPy. There are no official NumPy 64 bit builds available for Windows. This article is a short note on how to set up NumPy on a 64-bit Windows, and it was originally posted on Jan-Philip Gehrcke’s blog.
