我一直试图在Windows 64位上获得NumPy for Python 2.7,但是大家提到的页面http://www.lfd.uci.edu/~gohlke/pythonlibs/并没有在我的任何设备上打开.
还有其他地方我可以找到吗？
解决方法:
我建议使用WinPython,一个适用于Windows的Python 2.7发行版,包含32位和64位版本.
07.01由WinPython创建者解释为什么通常很难找到64位Windows NumPy：
According to experienced developers, there is no decent open-source (free) Fortran compiler for the Windows 64bit platform. As a consequence, it’s impossible to build NumPy or SciPy on this platform using only free and open-source tools. That’s why there is no official Windows 64bit binaries for these two libraries. The only ready-to-use installers available out there were prepared by Christoph Gohlke (using Intel Fortran compiler, a.k.a. ‘ifort’) and these are clearly unofficial binaries. Furthermore, Christoph has built two different installers for NumPy: one unoptimized and one optimized with the Intel Math Kernel Library (MKL), hence providing better performance. And Gohlke’s SciPy 64bit binary package (the only one available freely online) require NumPy MKL. The problem is that, according to Christoph Gohlke, the MKL license does not allow me (or anyone else) to redistribute these binaries, unless I have purchased such a license. It is still unclear to me if the end user would also require this license too. Hopefully no. Let’s assume that. Besides, after reading carefully the Intel MKL License terms, I’m quite sure that I can redistribute the MKL-based NumPy built because it’s just runtime redistribution. So I think I will purchase an Intel Fortran Compiler license (including MKL) to be able to rebuild NumPy and SciPy in the near future but in the meantime I will just redistribute the packages built by Christoph Gohlke.
