python中的yolov5结合PyQt5,使用QT designer设计界面没正确启动的解决方法
一、窗体设计test:
默认你已经设计好了窗体后:
这时你需要的是保存生成的untitle.ui到某个文件夹下,然后在命令行中奖.ui转换为.py(,通过pyqt5提供的转换工具,将ui文件转换成python的代码)
pyuic5.bat -o main.py untitled.ui
或者使用在PyCharm中安装的工具:
然后你会看到main.py中的代码发生了变化,这时你想通过命令去运气起来,发现运行没有反应,遇
到问题,解决方法如下:
在该转变的main.py文件内部加入以下的代码:
如果加入后提示缺少某个引入的参数,添加上即可
if __name__ == '__main__':
import sys
app = QtWidgets.QApplication(sys.argv)
ui = Ui_MainWindow()
mainWindow = QtWidgets.QMainWindow()
ui.setupUi(mainWindow)
mainWindow.show()
sys.exit(app.exec())
我的测试的转变后的代码案例如下:文章来源:https://www.toymoban.com/news/detail-723415.html
