Ошибка js: Uncaught ReferenceError: Plotly is not defined

Question

Мне нужно отобразить plotly график в окне PyQt5.
Тут https://stackoverflow.com/questions/60522103/how-to-have-plotly-graph-as-pyqt5-widget на такой вопрос уже ответили.
Но после запуска скрипта оттуда выходит ошибка:

js: Uncaught ReferenceError: Plotly is not defined.

Подскажите пожалуйста, как решить эту проблему.

#pip install PyQtWebEngine 
from PyQt5 import QtCore, QtWidgets, QtWebEngineWidgets
import plotly.express as px


class Widget(QtWidgets.QWidget):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.button = QtWidgets.QPushButton('Plot', self)
        self.browser = QtWebEngineWidgets.QWebEngineView(self)

        vlayout = QtWidgets.QVBoxLayout(self)
        vlayout.addWidget(self.button, alignment=QtCore.Qt.AlignHCenter)
        vlayout.addWidget(self.browser)

        self.button.clicked.connect(self.show_graph)
        self.resize(500,400)

    def show_graph(self):
        df = px.data.tips()
        fig = px.box(df, x="day", y="total_bill", color="smoker")
        fig.update_traces(quartilemethod="exclusive") # or "inclusive", or "linear" by default
        self.browser.setHtml(fig.to_html(include_plotlyjs="cdn"))
        #print(fig.to_html(include_plotlyjs="cdn"))

if __name__ == "__main__":
    app = QtWidgets.QApplication([])
    widget = Widget()
    widget.show()
    app.exec()

У меня тоже как-то по другому ругалось.

Обновил plotly:

python.exe -m pip install --upgrade plotly

и все ok.

from PyQt5 import QtCore, QtWidgets, QtWebEngineWidgets
import plotly.express as px


class Widget(QtWidgets.QWidget):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.button = QtWidgets.QPushButton('Plot', self)
        self.browser = QtWebEngineWidgets.QWebEngineView(self)

        vlayout = QtWidgets.QVBoxLayout(self)
        vlayout.addWidget(self.button, alignment=QtCore.Qt.AlignHCenter)
        vlayout.addWidget(self.browser)

        self.button.clicked.connect(self.show_graph)
        self.resize(500,400)

    def show_graph(self):
        df = px.data.tips()
        fig = px.box(df, x="day", y="total_bill", color="smoker")
        
        fig.update_traces(quartilemethod="exclusive")               # or "inclusive", or "linear" by default
#        fig.update_traces(quartilemethod="inclusive")        
        
        self.browser.setHtml(fig.to_html(include_plotlyjs="cdn"))
        #print(fig.to_html(include_plotlyjs="cdn"))

if __name__ == "__main__":
    app = QtWidgets.QApplication([])
    widget = Widget()
    widget.show()
    app.exec()
