As per above google coral November updates new Mendel 4.0 has the support of OpenCV but when I installed Mendel 4.0 it is unable to import cv2. Please let me know do I've to follow any further steps to install OpenCV in Mendel 4.0
Following steps have to be done:
If you have a fresh image make sure you update your system packages
sudo apt-get update
sudo apt-get dist-upgrade
Install OpenCV
sudo apt install python3-opencv
Test installation
python3 -c 'import cv2; print(cv2.__version__)'
I can confirm, that openCV can be installed using sudo apt install python3-opencv
. If it does not work, check if your board is connected to the internet (see coral documentation here).
