Numpy 在 64 位 windows 上不适用于 32 位 Python

Question

我有一个 Python 2.7.8。 32 位安装在 Windows 10 64 位上。当我尝试 import numpy 时，出现以下错误：

ActivePython 2.7.8.10 (ActiveState Software Inc.) based on

我已经从 this page

安装了 numpy-1.9.2+unoptimized-cp27-none-win32.whl

Answer 1

来自 CGohlke's page：

The binaries are compatible with the official CPython distribution on Windows >=6.0. Chances are they don't work with custom Python distributions included with Blender, Maya, ArcGIS, OSGeo4W, ABAQUS, Cygwin, Pythonxy, Canopy, EPD, Anaconda, WinPython etc.

我的猜测是ActivePython也是如此。

我建议安装来自 here, or installing the Anaconda distribution from here 的官方 CPython Windows 二进制文件，它带有 numpy、scipy、matplotlib 和大量其他科学 Python包。
