Hi, I filely got it working. Here is the Script I used:
echo “OpenCV installation by learnOpenCV.com”
Define OpenCV version to install
cvVersion=“master”
Clean build directories
rm -rf opencv/build
rm -rf opencv_contrib/build
Create directory for installation
mkdir installation
mkdir installation/OpenCV-"$cvVersion"
Save current working directory
cwd=$(pwd)
sudo apt -y update
sudo apt -y upgrade
sudo apt -y remove x264 libx264-dev

############ For Python 3 ############
create virtual environment
python3 -m venv OpenCV-"$cvVersion"-py3
echo “# Virtual Environment Wrapper” >> ~/.bashrc
echo “alias workoncv-$cvVersion=“source $cwd/OpenCV-$cvVersion-py3/bin/activate”” >> ~/.bashrc
source “$cwd”/OpenCV-"$cvVersion"-py3/bin/activate
now install python libraries within this virtual environment
