NumPy库导入错误：DLL加载失败：无法找到指定的程序

我在使用Windows 10上的Visual Studio 2017学习python。当我试图将NumPy库导入到我的代码中时，出现此错误。我曾尝试卸载并重新安装，在ImportError: DLL load failed when importing Numpy installed in conda virtual environment的每条指令中查找libiomp5md.dll，但以no为准。NumPy库导入错误：DLL加载失败：无法找到指定的程序

Traceback (most recent call last):

from . import multiarray 
ImportError: DLL load failed: The specified procedure could not be found. 

During handling of the above exception, another exception occurred:

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. 

Original error was: DLL load failed: The specified procedure could not be found.

确保使用Python ** 3.6.1 **。请参阅[Python issue＃29943]（https://bugs.python.org/issue29943） – cgohlke

要短：

尝试将Python环境切换到Python 2.7，它可以解决这个问题。

我也有同样的问题。我注意到你使用Python 3.6（以前，我也使用Python 3.6）。而我使用Python 2.7后，它解决了我的问题。

我想用numpy & scipy库和VS2017给我带来了很多错误！我做了一些搜索之后，我通过安装whl包来解决所有问题http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy手动

您安装了哪个'whl'软件包以及哪个版本的Python？ Python 3.6还是Python 2.7？ –

@ HoangV.Pham现在我使用Python 2.7 –

最新版本好像坏了。安装旧版本：

pip3 uninstall numpy 
pip3 install 'numpy<1.13'
