如何使用 Python、PyQt5 和 Pyinstaller 修复未正确显示的按钮

Question

我使用 Qt Designer 创建了一个界面，并使用 PyQt5 将其集成到我的 python 代码中。然后我使用 Pyinstaller 创建了一个 exe 文件，界面在我使用 Windows 10 Home 的笔记本电脑上显示正常。然而，使用 Windows 10 Pro 在不同的 windows 机器上进行测试显示按钮和标签全部被剪掉，字体错误，如下所示。例如，顶部标题应该是 GEODISTANCE CALCULATOR' 但只显示 'GEODISTANCE CA'。是什么导致了这种不兼容，我该如何解决？

我有下面的示例代码供任何想要测试示例的人使用：

from PyQt5 import uic, QtWidgets
import sys

app = QtWidgets.QApplication(sys.argv)

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

sys.exit(app.exec_())

从 Qt Designer 派生的 ui 文件的完整代码如下所示，可以通过将代码复制并粘贴到文本编辑器并将文件另存为 'interface.ui' 来重新创建该文件:

此问题已通过添加更多代码行解决，如下所示。有人已经发布了这个答案，但他们删除了它可能认为它是错误的，因为我花了一段时间才回复他们结果，所以谢谢！

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_())
