非常感谢这个大神，我纠结了好久这个问题！

IOError: [Errno 13] Permission denied: ‘d:\python27\Lib\site-packages\numpy\core\multiarray.pyd’

最终发现是在安装的同时，有在GUI shell中用import numpy，导致了multiarray.pyd文件的写保护

退出了shell界面，重新再安装numpy-1.11.2+mkl-cp27-cp27m-win32.whl，

问题解决：

D:\Python27\Scripts>pip2.7 install C:\Users\rao\Downloads\numpy-1.11.2+mkl-cp27-cp27m-win32.whl
