Windows环境中安装Openvino的步骤此处不做说明,可参见官网教程:https://docs.openvinotoolkit.org/2019_R2/_docs_install_guides_installing_openvino_windows.html#set-the-environment-variables

一定要设置setupvars.bat中的环境变量 (C:\Program Files (x86)\IntelSWTools\openvino\bin目录下)，启动cmd后执行setupvars.bat或者将setupvars.bat脚本中的环境变量手动添加到Path中:

当在python环境下导入openvino模块(openvino目录已复制到python的Lib目录下的site-packages中),如:

from openvino.inference_engine import IENetwork, IEPlugin

报如下错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python\Python36\lib\site-packages\openvino\inference_engine\__init__.py", line 1, in <module>
    from .ie_api import *
ImportError: DLL load failed: 找不到指定的模块。

解决办法:
将

C:\Program Files (x86)\IntelSWTools\openvino\deployment_tools\inference_engine\bin\intel64\Release

配置到PATH环境变量中即可。其中C:\Program Files (x86)\IntelSWTools为Openvino的默认安装路径。
配置后即可成功导入:
