Why does QtConsole error out when I try to convert it to bundle in pyinstaller?

Question

My qtconsole code is this:

import sys
from qtpy import QtWidgets

from qtconsole.rich_jupyter_widget import RichJupyterWidget
from qtconsole.manager import QtKernelManager

# The ID of an installed kernel, e.g. 'bash' or 'ir'.
USE_KERNEL = 'python3'

def make_jupyter_widget_with_kernel():
    """Start a kernel, connect to it, and create a RichJupyterWidget to use it
    """
    kernel_manager = QtKernelManager(kernel_name=USE_KERNEL)
    kernel_manager.start_kernel()

    kernel_client = kernel_manager.client()
    kernel_client.start_channels()

    jupyter_widget = RichJupyterWidget()
    jupyter_widget.kernel_manager = kernel_manager
    jupyter_widget.kernel_client = kernel_client
    return jupyter_widget

class MainWindow(QtWidgets.QMainWindow):
    """A window that contains a single Qt console."""
    def __init__(self):
        super().__init__()
        self.jupyter_widget = make_jupyter_widget_with_kernel()
        self.setCentralWidget(self.jupyter_widget)

    def shutdown_kernel(self):
        print('Shutting down kernel...')
        self.jupyter_widget.kernel_client.stop_channels()
        self.jupyter_widget.kernel_manager.shutdown_kernel()

if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    window = MainWindow()
    window.show()
    app.aboutToQuit.connect(window.shutdown_kernel)
    sys.exit(app.exec_())

it successfully compiles when I run it but when I click on the finished pyinstaller (pyinstaller --onefile main.py or pyinstaller --windowed --onedir Yuro.py) bundle, this qtconsole errors out with message:

I took this qtconsole code from the qtconsole github: "https://github.com/jupyter/qtconsole/blob/master/examples/embed_qtconsole.py." Thank you in advance for your help.
