"import numpy as np" ImportError: No module named numpy

问题：没有安装numpy

解决方法：

下载文件，安装

numpy-1.8.2-win32-superpack-python2.7

安装运行import numpy，出现

Traceback (most recent call last):
  File "", line 1, in 
    import numpy
  File "C:\Python27\lib\site-packages\numpy\__init__.py", line 153, in 
    from . import add_newdocs
  File "C:\Python27\lib\site-packages\numpy\add_newdocs.py", line 13, in 
    from numpy.lib import add_newdoc
  File "C:\Python27\lib\site-packages\numpy\lib\__init__.py", line 8, in 
    from .type_check import *
  File "C:\Python27\lib\site-packages\numpy\lib\type_check.py", line 11, in 
    import numpy.core.numeric as _nx
  File "C:\Python27\lib\site-packages\numpy\core\__init__.py", line 6, in 
    from . import multiarray
ImportError: DLL load failed: %1 不是有效的 Win32 应用程序。

原因是：python 装的是64位的，numpy装的是32位的

重新安装numpy为：numpy-1.8.0-win64-py2.7
