无法在python中导入numpy库

Question

我已经安装了python 3.6并通过pip添加了numpy模块，但是在尝试导入库时出现以下错误。 请在这里帮助：

>>> import numpy
Traceback (most recent call last):
  File "C:\Users\as338011\AppData\Local\Programs\Python\Python36\lib\site-packages\numpy\core\__init__.py", line 16, in
<module>
    from . import multiarray
ImportError: DLL load failed: The specified procedure could not be found.

在处理上述异常期间，发生了另一个异常：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\as338011\AppData\Local\Programs\Python\Python36\lib\site-packages\numpy\__init__.py", line 142, in <mod
ule>

    from numpy.lib import add_newdoc

    import numpy.core.numeric as _nx
  File "C:\Users\as338011\AppData\Local\Programs\Python\Python36\lib\site-packages\numpy\core\__init__.py", line 26, in
<module>
    raise ImportError(msg)
ImportError:
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.

原始错误是：DLL加载失败：找不到指定的过程。

如终端所提示，您可能安装了错误版本的numpy。 如果您使用的是python 3，则需要安装pip3 numpy，而不要使用普通的（python 2.7）pip。 无论哪种方式，您都应尝试重新安装numpy，或者如果仍然无法正常工作，则可以从源代码进行构建。 这是基于这样的事实，即问题似乎出在numpy软件包上，而不是系统本身。
