1、流程：

训练YOLOv5模型-----转化pt文件为onnx-----转化为xml+bin-----放入预测代码中

2、预测代码更改：

1.CPU、GPU的调动选择 

 2.模型路径

 3.名称类型（要预测的种类）

 4.异步模式是否开启（如果使用MP4文件记得改0为mp4路径并且关闭异步模式）

  3、主要参考文章

文二中方法一可行 注意要先换pip、conda源，不然真的慢。清华源有时候会有问题，可以多加两个。

这篇文章中推荐降python。网上主流就是降opencv/重装pyqt、opencv-python。降python之后很多要重新配置，很麻烦。

也尝试过给摄像头加权限。应当是程序问题。YOLOv5可以正常调用摄像头进行检测 

之后就不用摄像头了干脆 把输入源改成了视频

4.4    Cannot find reference 'inference_engine' in 'imported module openvino

调用SDK的时候一直报错，代码编译不通过 无法import openvino.inference /runtime

最后解决是更改了文件名称 原来叫openvino，改成openvino111就跑通了

python 绝对路径 import_米饭的白色的博客-优快云博客_import 绝对路径 尝试过绝对路径import 可能操作不正确 没起作用 理论上应该起作用的

还有说法是把openvino移动到YOLOv5根目录下。链接中方法理论上是可以的，但是我没什么用

4.6 Failed to create plugin /home/amov/anaconda3/envs/yolov5/lib/python3.9/site-packages/openvino/libs/libopenvino_intel_gpu_plugin.so for device GPU

[CLDNN ERROR]. clGetPlatformIDs error -1001同时出现这个

理论上是因为显卡及其驱动问题 导致的 但是因为在openvino中本来就可以不使用GPU

把GPU的调用去掉就好了
