C++ 调用python3 ImportError: cannot import name 'multiarray'解决方法

VS2017+python3.6

C++调用python时报错如下。

Traceback (most recent call last):
  File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64\lib\site-packages\numpy\core\__init__.py", line 16, in <module>
    from . import multiarray
ImportError: cannot import name 'multiarray'

During handling of the above exception, another exception occurred:

    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.

Original error was: cannot import name 'multiarray'

项目属性里重新配置一下release，然后用release就好了。

配置方法：

1. 项目–>属性–>左上角配置改成Release–>C/C++–>常规–>附加包含目录 添加python安装目录中include目录

2. 项目–>属性–>链接器–>常规->附加库目录

3. 链接器–>输入–>附加依赖项 添加python36.lib

python3,print()别忘了改。自己加上import numpy as np试一下。
