1.windows10 64位 OpenVINO安装教程
博主的配置：
安装的vs2019版本，安装过程中遇到Q1；
openvino安装路径更换到D盘，测试过程中会遇到Q2。
2.Windows 10 系统安装 OpenVINO (2022.1.0)
Q1：‘vswhere’ 不是内部或外部命令，也不是可运行的程序或批处理文件。
'vswhere' 不是内部或外部命令，也不是可运行的程序或批处理文件。 Build tools for Visual Studio 2015 / 2017 / 2019 cannot be found. If you use Visual Studio 2017, please download and install build tools from https://www.visualstudio.com/downloads/#build-tools-for-visual-studio-2017 Error
原因：安装的vs2019版本
解决方法：重新安装2017版本
Q2：could not find any instance of Visual Studio.
could not find any instance of Visual Studio. -- Configuring incomplete, errors occurred! See also "D:/Program File/Intel/openvino_2020.3.355/deployment_tools/inference_engine/samples/cpp/CMakeFiles/CMakeOutput.log". Error
2.运行demo_squeezenet_download_convert_run.bat报错原因： OpenVINO 安装到D盘
解决办法：把.bat 脚本中的“cd”命令全都改成“cd /d”，或者把 OpenVINO 安装到 C盘。

解决方法：
运行demo_security_barrier_camera.bat遇到同样的问题，解决方法一样。
3.运行D:Program FileIntelopenvino_2020.3.355deployment_toolsmodel_optimizer>python mo_onnx.py --input_model E:workyolov5yolov5s.onnx报错4。运行python export.py --weights yolov5s.pt --img 640 --batch 1报错解决方法：
pip uninstall nuimpy
pip install numpy==1.15.1
首先要修改export.py文件内的opset=10
> [ ERROR ] Cannot infer shapes or values for node "Resize_118". [ ERROR ] operands could not be broadcast together with shapes (4,) (0,) [ ERROR ] [ ERROR ] It can happen due to bug in custom shape infer function. [ ERROR ] Or because the node inputs have incorrect values/shapes. [ ERROR ] Or because input shapes are incorrect (embedded to the model or passed via --input_shape). [ ERROR ] Run Model Optimizer with --log_level=DEBUG for more information. [ ERROR ] Exception occurred during running replacer "REPLACEMENT_ID" ( ): Stopped shape/value propagation at "Resize_118" node. For more information please refer to Model Optimizer FAQ (https://docs.openvinotoolkit.org/latest/_docs_MO_DG_prepare_model_Model_Optimizer_FAQ.html), question #38.
5.在python下运行from openvino.inference_engine import IECore，出现from .ie_api import * ImportError: DLL load failed报错解决方法：python export.py --weights yolov5s.pt --include torchscript onnx
第一步：按下图添加代码
第二步：执行setupvars.bat获取path的最新结果
第三步：复制新增的环境变量信息，手动添加的系统环境变量path中
6.提示ImportError: DLL load failed while importing ie_api: 找不到指定的模块。1.yololibsite-packagesopenvinoinference_engine_init_.py下的错误
Traceback (most recent call last): File "F:/DLproject/YOLOX-main/demo/OpenVINO/python/openvino_inference.py", line 15, infrom openvino.inference_engine import IECore File "E:ProgramDataAnaconda3envsyololibsite-packagesopenvinoinference_engine__init__.py", line 31, in from .ie_api import * ImportError: DLL load failed while importing ie_api: 找不到指定的模块。
解决方法：在__init__.py文件中的对应位置加上：os.environ[‘PATH’] = os.path.abspath(lib_path) + ‘;’ + os.environ[‘PATH’]

2.pythonpython3.7openvinoinference_engine_init_.py下的错误
问题描述：
解决方法：在环境变量中新增如下两项
7.运行mo.py文件1.用netron查看onnx文件，查找transpose
2.点击查到的transpose,查看其对应的conv
3.点击conv，查看name
4.运行如下代码
python mo.py --input_model yolov5s.onnx -s 255 --reverse_input_channels --output Conv_156 （最后填写的是第3步的name）8.模型推理
在https://github.com/violet17/yolov5_demo下载yolo5_demo.py文件，运行如下代码
python yolov5_demo.py -i E:workyolov5dataimagesbus.jpg -m yolov5s.xml
注：每次运行前需要先运行openvinobin下的setupvars.bat文件
