如何使用Python，PyQt5和Pyinstaller修复无法正确显示的按钮

Question

I created an interface using Qt Designer and integrated it into my python code using PyQt5. I then created an exe file using Pyinstaller and the interface shows up fine on my laptop using Windows 10 Home. However testing on a different windows machine using Windows 10 Pro shows the buttons and labels all cut out , with wrong font and all as shown below. For example, the top title should be GEODISTANCE CALCULATOR' but only shows 'GEODISTANCE CA'. What causes this incompatibility and how can I fix this?

I have the example code below for anyone who would like a sample to test on:

from PyQt5 import uic, QtWidgets
import sys

app = QtWidgets.QApplication(sys.argv)

window = uic.loadUi('interface.ui')
window.show()

sys.exit(app.exec_())

The complete code for the ui file derived from Qt Designer is as shown below and the file can be recreated by copying and pasting the code to a text editor and saving the file as 'interface.ui':

Answer 1

This issue is solved by adding a few more lines of code as shown below. Someone already posted this answer but they deleted it probably thinking its wrong as it took me a while to get back to them with the results, so thank you!

from PyQt5 import uic, QtWidgets
import sys

# Enable high DPI scaling
if hasattr(QtCore.Qt, 'AA_EnableHighDpiScaling'):
    PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling, True)

if hasattr(QtCore.Qt, 'AA_UseHighDpiPixmaps'):
    PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_UseHighDpiPixmaps, True)
app = QtWidgets.QApplication(sys.argv)

window = uic.loadUi('interface.ui')
window.show()

sys.exit(app.exec_())
