我刚刚测试了这段代码，它工作得很好.您需要先安装openvino，然后运行setupvars.bat文件以初始化openvino环境.完成后，您可以运行您的代码，它将开始检测您的面孔.我在具有12Gb RAM的Intel i5上进行了测试，得到的速度为23-25fps.

I just tested this code and it works perfectly fine. You need to install openvino first and then run setupvars.bat file in order to initialize the openvino enviroment. Once that is done, you can run your code and it will start detecting your face. I tested this on Intel i5 with 12Gb RAM and I was getting 23-25fps which is good.
