使用PyInstaller后，FigureCanvas未解释为QtWidget

问题描述

我从matplotlib对该示例进行了少许修改: https://matplotlib.org/gallery/user_interfaces/embedding_in_qt_sgskip.html

I have a slight modified version of this example from matplotlib: https://matplotlib.org/gallery/user_interfaces/embedding_in_qt_sgskip.html

唯一改变的是导入，因为我使用的是 PySide2，所以导入看起来像这样:

The only thing changed is the imports since I am using PySide2, so the imports looks like this:

from PySide2 import QtCore, QtWidgets
from matplotlib.backends.backend_qt5agg import (FigureCanvasQTAgg as FigureCanvas, NavigationToolbar2QT as NavigationToolbar)
from matplotlib.figure import Figure

在 pycharm 中运行代码或单独运行脚本时，这可以正常工作，但是在使用 PyInstaller 创建 .exe 后，我收到以下错误:

This works fine when running the code in pycharm, or running the scrips by itself, however after an .exe is created with PyInstaller I get the following error:

TypeError: 'PySide2.QtWidgets.QBoxLayout.addWidget' called with wrong argument types:
  PySide2.QtWidgets.QBoxLayout.addWidget(FigureCanvasQTAgg)
Supported signatures:
  PySide2.QtWidgets.QBoxLayout.addWidget(PySide2.QtWidgets.QWidget, int=0,
  PySide2.QtCore.Qt.Alignment=Default(Qt.Alignment))
  PySide2.QtWidgets.QBoxLayout.addWidget(PySide2.QtWidgets.QWidget)

似乎FigureCanvasQtAgg不再被视为QWidget，因此无法将其添加到布局中.

It seems as the FigureCanvasQtAgg is no longer recognized as a QWidget, so it can't be added to the layout.

我已经尝试添加这些行来建议 pyside 建议 here:

I've tried adding these lines to suggest pyside as suggested here:

os.environ["QT_API"] = "PySide2"
matplotlib.use('Qt5Agg')
matplotlib.rcParams['backend.qt5']='PySide2'

但是，这不会更改exe的错误消息.在 pycharm 中它仍然运行良好.

However that does not change the error message of the exe. In pycharm it still runs fine.

替换此行后，看来PySide2 + PyInstaller出现了问题:

from PySide2 import QtCore, QtWidgets

用这一行:

from PyQt5 import QtCore, QtWidgets

即使在使用 PyInstaller 后它也能工作.

It works even after using PyInstaller.

但是我想使用PySide2代替PyQt5，有人知道解决此问题的方法吗?

But I want to use PySide2 instead of PyQt5, anyone know a way to solve this?

推荐答案

对于PySide2，当我使用PySide 5.13版本时，我也遇到类似的问题.

For PySide2, I have a similar problem when I use the version PySide 5.13.

然而，它对于 PySide 5.6 版很好.

It is however, working fine for PySide version 5.6.

有趣的是，问题看起来与 matplotlib 包装器有关.FigureCanvasQTAgg 的包装器似乎发生了变化.正在运行的包装器是:Shiboken.ObjectType.虽然那个不起作用，但包装器是:sip.wrappertype.

Interestingly, the issue looks like with the matplotlib wrapper. It seems there is a change in the wrapper for FigureCanvasQTAgg. The one that is working, the wrapper is: Shiboken.ObjectType. While the one that is not working, the wrapper is: sip.wrappertype.
