需要快速编写一个GUI图形界面

pip install pyqt5
pip install pyqt5-tools

然后去conda环境中查找启动程序

F:\APP\miniconda\envs\yolov8gui\Lib\site-packages\qt5_applications\Qt\bin\designer.exe

双击可以启动，我们可以把它发送到桌面快捷方式

准备设计图，这是我用微信截图自己画的：

然后开始设计进行测试：

设计好的样子如下：

然后点击保存，我保存到了项目的目录下：G:\bsh\yolov8\xcbGUI\demo.ui

然后考虑使用demo.ui文件生成python代码
点击pycharm的文件——设置——工具——外部工具——
点击加号，新增pyuic5的外部工具，
名称随便写，程序去conda的envs里找，例如我的是：F:\APP\miniconda\envs\yolov8gui\Scripts\pyuic5.exe
实参需要注意，如果填写：
$FileName$ -o $FileNameWithoutExtension$.py
那么只可以调用
G:\bsh\yolov8\目录下的.ui文件来生成.py文件，
想要指定目录，请按照我的方法：
xcbGUI\$FileName$ -o xcbGUI\$FileNameWithoutExtension$.py
就可以生成
G:\bsh\yolov8\xcbGUI目录下的文件了
最后的工作目录可以写：
$ProjectFileDir$

生成后的代码自己加入类的初始化
class Ui_MainWindow(object):

class Ui_MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi(self)
        self.retranslateUi(self)
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(1128, 1009)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
       
     xxxxxxxxx
     xxxxxx

末尾加入启动程序：

if __name__ == '__main__':
    app = QApplication(sys.argv)
    MainWindow1 = QMainWindow()     #MainWindow1随便改
    ui = Ui_MainWindow()             #随便改
    ui.setupUi(MainWindow1)
    MainWindow1.show()
    sys.exit(app.exec_())

然后增加点击逻辑，调用后台程序，使得程序可以运行，效果如下：
