使用 MYRIAD 重启后 OpenVINO YOLOv4 推理设备未出现，但可以使用 CPU
OpenVINO YOLOv4 inference device didn't appear after reboot with MYRIAD but could work with CPU
我的环境是Windows11，版本openvino_2021.4.752。
当我尝试 运行 object_detection_demo.py 在推理引擎的 demos 文件夹中时， N/A 结果将使用 CPU，我稍后会提到的 MYRIAD 问题将发生在我的 NCS2 上。

因此，我尝试在 GitHub 上 运行 TNTWEN/OpenVINO-YOLOV4，并且它与 CPU 一起使用很有帮助。
但是，如果我使用 MYRIAD 作为我的推理设备，NCS2 会出现错误 ncDeviceClose:1852 Device didn't appear after reboot。

我认为这是使用 NCS2 的 YOLOv4 的错误。
毕竟，我可以使用我的 CPU 在此 GitHub 实现中成功完成 YOLOv4 推理工作，其中 object_detection_demo_yolov3_async.py 2021.3 pythondemo文件夹.
此问题（运行 带有对象检测的 YOLOv4 模型 Python MYRIAD 设备上的演示）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，我已经使用对象检测 C++ 演示验证了 YOLOv4 模型，它运行良好。现在，请使用对象检测 C++ 演示作为替代演示。
我的环境是Windows11，版本openvino_2021.4.752。
当我尝试 运行 object_detection_demo.py 在推理引擎的 demos 文件夹中时， N/A 结果将使用 CPU，我稍后会提到的 MYRIAD 问题将发生在我的 NCS2 上。

我认为这是使用 NCS2 的 YOLOv4 的错误。
毕竟，我可以使用我的 CPU 在此 GitHub 实现中成功完成 YOLOv4 推理工作，其中 object_detection_demo_yolov3_async.py 2021.3 pythondemo文件夹.
此问题（运行 带有对象检测的 YOLOv4 模型 Python MYRIAD 设备上的演示）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，我已经使用对象检测 C++ 演示验证了 YOLOv4 模型，它运行良好。现在，请使用对象检测 C++ 演示作为替代演示。
