How to save background image in python when creating .exe?

Question

Python

When creating an exe file, the background image is lost, but when I throw it into the dist folder, everything works as it should. How to push it into exe. Here is the code:

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QAction, qApp, QWidget, QApplication

class Sert(object):

  def setupUi(self, MainWindow):
    MainWindow.setObjectName("MainWindow")
    MainWindow.setMinimumSize(240, 320)
    MainWindow.setMaximumSize(240, 320)
    self.centralwidget = QtWidgets.QWidget(MainWindow)
    self.centralwidget.setObjectName("centralwidget")
    self.lable = QtWidgets.QLabel(self.centralwidget)
    self.lable.setGeometry(QtCore.QRect(120, 36, 181, 21))
    self.lable.setObjectName("lineEdit")
    MainWindow.setCentralWidget(self.centralwidget)
    self.statusbar = QtWidgets.QStatusBar(MainWindow)
    self.statusbar.setObjectName("statusbar")
    MainWindow.setStatusBar(self.statusbar)
# Создание меню бара
    MainWindow.statusBar()
    self.menubar = MainWindow.menuBar()
# Задний фон
    pal = MainWindow.palette()
    pal.setBrush(QtGui.QPalette.Normal, QtGui.QPalette.Window, QtGui.QBrush(QtGui.QPixmap("Hell.jpg")))
    MainWindow.setPalette(pal)

    self.retranslateUi(MainWindow)
    QtCore.QMetaObject.connectSlotsByName(MainWindow)
  def retranslateUi(self, MainWindow):
    _translate = QtCore.QCoreApplication.translate
    MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))

if __name__ == '__main__':
  import sys
  app = QApplication(sys.argv)
  window = Sert()
  window.show()
  sys.exit(app.exec_())

If possible, please describe the solution in detail. And then I still don’t know PyQt5 well. Exe created with pyinstaller.
