[Numpy-discussion] Why I cannot import NumPy?

[<le...@em...>]

After installation, I cannot import NumPy.
I tried to run setup.py in the numpy directory. But the following error occurs:

IDLE 1.1.2
>>> ================================ RESTART ================================
>>>
Assuming default configuration (distutils\command/{setup_command,setup}.py was

    config = setup_module.configuration(*args)

configuration
    open(generate_umath_py,'U'),generate_umath_py,
IOError: [Errno 2] No such file or directory:
'core\\code_generators\\generate_umath.py'


Can someone tell me how to solve this problem? There is no directory names
code_generators in the code directory.

Thanks
