import numpy给出ImportError：DLL加载失败：％1不是有效的Win32应用程序

Question

我正在为visual studio express 2013使用python工具。我无法在其中导入numpy。可以成功导入其他模块，如re和math

import numpy会出现以下错误：

Traceback (most recent call last):
File "`<stdin>`", line 1, in `<module>`

 File "C:\Python27\lib\site-packages\numpy\__init__.py", line 153, in <module>
from . import add_newdocs
 File "C:\Python27\lib\site-packages\numpy\add_newdocs.py", line 13, in <module>
from numpy.lib import add_newdoc
 File "C:\Python27\lib\site-packages\numpy\lib\__init__.py", line 8, in <module>
from .type_check import *
File "C:\Python27\lib\site-packages\numpy\lib\type_check.py", line 11, in <module>
import numpy.core.numeric as _nx
File "C:\Python27\lib\site-packages\numpy\core\__init__.py", line 6, in <module>
from . import multiarray
ImportError: DLL load failed: %1 is not a valid Win32 application.

如何解决这个问题？
