Jetson nano could not install PyQt5 - python-3.x

Question

I am trying hard to install PyQt5 in my Jetson nano. However, there is one thing always annoys me.
here's the feedback message.

I've tried sudo pip3 install pyqt5 and it gave me

I also tried sudo apt-get install python3-pyqt5. It worked but when I imported PyQt5 by from pyqtgraph.Qt import QtCore, QtGui or from PyQt5.QtCore import QObject, pyqtSignal, it gave me

How do I fix this problem? Any suggestions or ideas could be a help.
Thank you.
