在Windows10中添加OpenVINO环境变量

【问题】每次都要手动运行OpenVINO自带的 C:\Program Files (x86)\Intel\openvino_2021.3.394\bin\setupvars.bat来初始化OpenVINO运行时环境，有没有一劳永逸的办法？

【解决方式】设置Windows10 环境变量path，把OpenVINO依赖库都添加进去；设置PYTHONPATH，把OpenVINO Python库都添加进去。

以OpenVINO 2021.3为例：
第一步， 手动添加下面的路径到Windows10环境变量path：

• C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\ngraph\lib;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\inference_engine\external\tbb\bin;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\inference_engine\bin\intel64\Release;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\inference_engine\bin\intel64\Debug;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\inference_engine\external\hddl\bin;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\inference_engine\external\omp\lib;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\inference_engine\external\gna\lib;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\model_optimizer;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\opencv\bin;

第二步：手动添加下面的路径到PYTHONPATH：

• C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\tools\post_training_optimization_toolkit;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\open_model_zoo\tools\accuracy_checker;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\python\python3.8;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\python\python3;
• C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\model_optimizer;

完毕！
