I had OpenCV 4.1.2 installed on my system with Cuda support and after installing OpenCV 4.8.0 (had to upgrade OpenCV because I needed to install MediaPipe 0.8) and running the command opencv_version I get 4.8.0 as the OpenCV version. But when I run python3 -c "import cv2; print(cv2.__version__)" or python3 -c "import cv2; print('OpenCV version:', str(cv2.__version__)); print(cv2.getBuildInformation())" it points to the older version and I get OpenCV version as 4.1.2 and it’s build details.

How do I make sure only 4.8.0 is used hereafter and not 4.1.2
After running the command python3 -c "import cv2; print('OpenCV version:', str(cv2.__version__)); print(cv2.getBuildInformation())" I need to see OpenCV version as 4.8.0 and not 4.1.2

Hi,

Please try to set the below global environment:

$ echo 'export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH' >> ~/.bashrc
$ echo 'export PYTHONPATH=/usr/local/lib/python3.6/site-packages/:$PYTHONPATH' >> ~/.bashrc
$ source ~/.bashrc

Thanks.
