我正在尝试实现一个 pyvista 情节

import sys
from qtpy import QtWidgets
from qtpy.QtWidgets import QMainWindow
import numpy as np
import pyvista as pv
from pyvistaqt import QtInteractor


class MainWindow(QMainWindow):

    def __init__(self, parent=None, show=True):
        QtWidgets.QMainWindow.__init__(self, parent)

        # create the frame
        self.frame = QtWidgets.QFrame()
        vlayout = QtWidgets.QVBoxLayout()

        # add the pyvista interactor object
        self.plotter = QtInteractor(self.frame)
        vlayout.addWidget(self.plotter.interactor)

        self.frame.setLayout(vlayout)
        self.setCentralWidget(self.frame)


        # Define a simple linear surface
        x = np.array([1,2,3,4,5,6,7,8,9])
        y = np.array([1,2,3,4,5,6,7,8,9])
        x, y = np.meshgrid(x, y)
        z = x*y

        self.grid = pv.StructuredGrid(x, y, z)
        self.z = z
        self.x = x
        self.y = y
        
        self.plotter.show_grid()
        self.plotter.add_mesh(self.grid, scalars=self.grid.points[:, -1], lighting=True, specular=0.5, smooth_shading=True, show_edges=True,
                              scalar_bar_args={'vertical': True})
        self.plotter.set_scale(xscale=1, yscale=x.ptp()/y.ptp(), zscale=x.ptp()/z.ptp())

    
        self.show()



if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = MainWindow()
    sys.exit(app.exec())

进入在 qtdesigner 中创建的 pyqt 选项卡小部件

from PyQt6 import QtCore, QtGui, QtWidgets
from pyvistaqt import QtInteractor


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.tabWidget = QtWidgets.QTabWidget(self.centralwidget)
        self.tabWidget.setGeometry(QtCore.QRect(0, 0, 801, 571))
        self.tabWidget.setObjectName("tabWidget")
        self.tab = QtWidgets.QWidget()
        self.tab.setObjectName("tab")
        self.widget = QtInteractor(self.tab)
        self.widget.setGeometry(QtCore.QRect(-11, -1, 811, 551))
        self.widget.setObjectName("widget")
        self.tabWidget.addTab(self.tab, "")
        self.tab_2 = QtWidgets.QWidget()
        self.tab_2.setObjectName("tab_2")
        self.tabWidget.addTab(self.tab_2, "")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 21))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.tabWidget.setTabText(self.tabWidget.indexOf(self.tab), _translate("MainWindow", "Tab 1"))
        self.tabWidget.setTabText(self.tabWidget.indexOf(self.tab_2), _translate("MainWindow", "Tab 2"))



if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec())

但我的尝试导致了各种错误。我不确定这些字段的正确信息是什么

在此处输入图像描述

我尝试了各种基类类型和名称，但我真的只是在黑暗中拍摄，因为我还不是很擅长。

即使在我尝试添加任何 pyvistaqt 逻辑之前，它也无法加载基本选项卡小部件模板，从而导致此错误

TypeError: QWidget(parent: QWidget = None, flags: Union[Qt.WindowFlags, Qt.WindowType] = Qt.WindowFlags()): argument 1 has unexpected type 'QWidget'

谁能帮我吗？我发现 pyqt 是一个非常复杂且难以理解的库，因为无论如何我都需要将 pyvista 图集成到 pyqt 中，所以我希望让这个图正常工作，这样我就可以玩弄它以试图理解 pyqt 的荒谬性.

我建议切换到 PyQT5，我相信 PyQT6 尚不支持。
