not changing OpenCV version for python2

[abdul-mannan-khan]

I followed these steps and tried to install OpenCV 4.2.0 for Jetson Nano Orin. However, it does not change OpenCV version for Python2. For Python3, it seemed to work fine. Here is the output of Python version check:

mannan@ubuntu:~/nano_build_opencv$ python -c "import cv2; print(cv2.__version__)"
4.5.4
mannan@ubuntu:~/nano_build_opencv$ python3 -c "import cv2; print(cv2.__version__)"
4.2.0

I am using Jetson Nano Orin 8GB version.

Any solution please? Thank you.
