带OpenVino的opencv dnn模块

Question

我在使用dnn模块时没有问题，但是我已经下载了openvino来使用带有引擎推理的dnn，当我转到OPENVINO中的OpenCV子目录并执行opencv_version_win32d.exe时，我无法加载opencv_dnn452d.dll库，我得到了这样的输出，这说明推理引擎有3个后端(ONETBB，TBB和OPENM)，但是它们都不能被正确检查：

我必须做什么才能让推理引擎正常工作？提前感谢您的答复

Answer 1

首先，也是最重要的，您需要安装OpenVINO的一些必备组件。

然后，您需要在您的系统中正确设置它。
