python - 如何在 Python shell 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.

我该如何解决这个问题？

Answer 1

该消息是不言自明的；当你调用 Python 时，你的工作目录不应该是 NumPy 源目录；应该安装 NumPy，你的工作目录应该不是它所在的目录。
