OpenVINO YOLOv4 推理设备在使用 MYRIAD 重启后未出现，但可以与 CPU 一起使用答案

【问题标题】：OpenVINO YOLOv4 inference device didn't appear after reboot with MYRIAD but could work with CPUOpenVINO YOLOv4 推理设备在使用 MYRIAD 重启后未出现，但可以与 CPU 一起使用

【问题描述】：

我的环境是带有openvino_2021.4.752版本的Windows 11。

当我尝试在推理引擎的 demos 文件夹中运行 object_detection_demo.py 时，使用 CPU 会出现 N/A 结果，我稍后会提到的 MYRIAD 问题将发生在我的 NCS2 上。

[ INFO ] Initializing Inference Engine...

[ INFO ] Loading network to CPU plugin...
[ INFO ] Starting inference...
To close the application, press 'CTRL+C' here or switch to the output window and press ESC key
Latency: N/A
FPS: N/A

因此，我尝试在 GitHub 上运行 TNTWEN/OpenVINO-YOLOV4，它与 CPU 配合使用很有帮助。

但是，如果我使用 MYRIAD 作为推理设备，则 NCS2 将出现错误 ncDeviceClose:1852 Device didn't appear after reboot。

我认为这是使用 NCS2 的 YOLOv4 的一个错误。

毕竟，我可以使用我的 CPU 在 2021.3 pythondemo 文件夹中的 object_detection_demo_yolov3_async.py 在这个 GitHub 实现上成功地完成 YOLOv4 推理工作。

【解决方案1】：

此问题（在 MYRIAD 设备上运行带有对象检测 Python 演示的 YOLOv4 模型）是 OpenVINO 2021.4.752 中的一个已知错误。我们的开发人员正在修复它。
另一方面，我已经使用 Object Detection C++ Demo 验证了 YOLOv4 模型，它运行良好。现在，请使用 Object Detection C++ Demo 作为替代演示。
