如何在Python sh中导入NumPy

Question

我曾尝试在Python中导入NumPy，但没有成功：

>>> import numpy as np
    x=np.array([[7,8,5],[3,5,7]],np.int32)

   Traceback (most recent call last):
   File "<pyshell#3>", line 1, in <module>
   import numpy as np
   File "C:\Python27\lib\numpy\__init__.py", line 127, in <module>
   raise ImportError(msg)
   ImportError: Error importing numpy: you should not try to import numpy from
   its source directory; please exit the numpy source tree, and relaunch
   your Python interpreter from there.

我该怎么解决？

这条消息相当简单；当您调用Python时，您的工作目录不应该是NumPy源目录；应该安装NumPy，并且您的工作目录不应该是它所在的目录。
