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： 图片：
