我需要在pyqt界面窗口中显示一些matplotlib.pyplot 3d图形。尝试在matplotlib_backend_qtquick库的帮助下实现something like this。
下面是我的main.py：

import os
import sys
from PyQt5 import QtQml, QtCore
from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication
from PyQt5.QtQml import QQmlApplicationEngine
from matplotlib_backend_qtquick.backend_qtquickagg import FigureCanvasQtQuickAgg
os.environ['QT_QUICK_CONTROLS_STYLE'] = "Material"
QtQml.qmlRegisterType(FigureCanvasQtQuickAgg, "Backend", 1, 0, "FigureCanvas")
app = QApplication(sys.argv)
engine = QQmlApplicationEngine()
engine.load(QUrl.fromLocalFile('/home/vovi/PycharmProjects/pyqt5-qtquick2-example-master/pyqt5-qtquick2-example-master/pyqt5_qtquick2_example/qml/main.qml'))
if not engine.rootObjects():
    sys.exit(-1)
sys.exit(app.exec_())

当我试图运行我的main.py时，我得到了一个回溯：

Traceback (most recent call last):
  File "/home/vovi/PycharmProjects/pyqt5-qtquick2-example-master/pyqt5-qtquick2-example-master/main.py", line 10, in <module>

我做错了什么？
