我已经集成了OpenVINO和PyQt5，在Windows11上完成了像这样的推理工作。

因为我们必须首先通过执行OpenVINO来初始化setupvars.bat环境。

我认为用户在进行推理之前手动初始化OpenVINO环境是很麻烦的。

因此，我尝试用我的PyQt5代码建立自动初始化程序.

from PyQt5 import QtWidgets
import os
#import time
import sys

if __name__ == '__main__':
    cwd = os.getcwd()
    os.chdir(r"C:\Program Files (x86)\Intel\openvino_2021.4.752\bin")    
    os.system("setupvars.bat")  
    #time.sleep(1)
    os.chdir(cwd)

    from controller import MainWindow  
    
    app = QtWidgets.QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec_())

在执行我的程序之后，虽然我可以在命令提示符上看到初始化的消息，但在此之后，无法找到名为“openvino”的模块。

Python 3.9.7
[setupvars.bat] OpenVINO environment initialized
Traceback (most recent call last):
  File "C:\Users\Hsien\Desktop\pyqt\start.py", line 16, in <module>
    from controller import MainWindow
  File "C:\Users\Hsien\Desktop\pyqt\controller.py", line 8, in <module>
    from inference_engine import openvino_inference_engine
  File "C:\Users\Hsien\Desktop\pyqt\inference_engine.py", line 1, in <module>
    from openvino.inference_engine import IECore, Blob, TensorDesc
ModuleNotFoundError: No module named 'openvino'

我还尝试使用sleep函数来延迟等待OpenVINO环境的设置，但没有成功。

但是这个问题可以通过在同一个命令提示符上手动执行C:\Program Files (x86)\Intel\openvino_2021.4.752\bin\setupvars.bat来解决。

如果我首先手动初始化OpenVINO环境，所有函数都执行得很好。

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

我的controller.py来了

        self.ui.ShowOutputImage.setScene(self.ui.ShowOutputImage.scene)  

    def display_logo(self):      
        self.img = cv2.imread("logo.png")
        height, width, channel = self.img.shape
        bytesPerline = 3 * width
        self.qimg = QImage(self.img, width, height, bytesPerline, QImage.Format_RGB888).rgbSwapped()
        self.ui.logo.setPixmap(QPixmap.fromImage(self.qimg))

首先，请注意，Windows 11不受OpenVINO的官方支持。因此，预计会出现问题。PyQt5与OpenVINO包的集成也是如此。

您可以在Windows中使用批处理文件创建OpenVINO setupvars.bat初始化。

创建一个批处理文件，初始化OpenVINO环境并启动您想要的软件(例如: VS2019)

在.bat文件中编写以下脚本：

@echo on

光盘箱

调用setupvars.bat

cd \2019\Community\Common7\IDE

调用devenv.exe

以管理员的身份运行.bat文件

由于OpenVINO和PyQt5的集成不受官方支持，因此没有具体的文档可作为指南。

另外，在开放式智能图书馆中实现了类似的集成。您可以参考此存储库以获得参考/解决方法。

除此之外，您还需要将OpenVINO推理引擎集成到应用程序中(为此目的只支持C++或Python )。您可以参考这个将推理引擎与Python应用程序集成。
