1.vs code 环境
  python
  Qt for Python
  PYQT Integration
  pip install PyQt5
  pip install pyqt5-tools -i https://pypi.douban.com/simple/
2.win10 下载 QT Creator
  http://download.qt.io/official_releases/qtcreator/4.13/4.13.3/
3.VS Code 中配置 PYQT Integration
  安装完成后，右键选择 Extension Settings，设置 pyuic5.exe 和 designer.exe 的路径

4.创建ui
  在vs code 的—.py中 右键，选择PyQt New Form 唤起 designer 设计器。
5.qt Designer
  新建 Main Window
  拖3个控件 line edit, push button, label
  保存
6.VS Code 中编译 .ui
  回到 VS Code，发现工作目录下多出 —.ui 文件，右键选择 PYQT：Compile Form，生成 Ui_—.py 文件
7.测试代码

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
 
import Ui_untitled

def incident():
    """
    docstring
    """
    print('点击按钮')
    q=ui.lineEdit.text()
    ui.label.setText(q)
 
if __name__ == '__main__':
    app = QApplication(sys.argv)
    MainWindow = QMainWindow() 
    ui = Ui_untitled.Ui_MainWindow()
    ui.setupUi(MainWindow)

    ui.pushButton.clicked.connect(incident)

    MainWindow.show()

    sys.exit(app.exec_())

8.运行截图

  点击pushbutton后

9.上树莓派
  sudo apt install -y python3-pyqt5.qsci python3-pyqt5.qtmultimedia python3-pyqt5.qtopengl python3-pyqt5.qtpositioning python3-pyqt5.qtquick python3-pyqt5.qtsensors python3-pyqt5.qtserialport python3-pyqt5.qtsql python3-pyqt5.qtsvg python3-pyqt5.qtwebchannel python3-pyqt5.qtwebkit python3-pyqt5.qtwebsockets python3-pyqt5.qtx11extras python3-pyqt5.qtxmlpatterns
10.然后吧–Ui_–.py和 --py放到树莓派上 直接运行 --.py 完美显示
