Import cv2 into program

I’m new at this
Is import cv2 the correct instruction for use with the latest version

When I try to run sample programs it say cv2 not found .

Thanks john.!..

yes, import cv2 is the correct way for now (OpenCV versions 2.x, 3.x, 4.x). it is recommended to use import cv2 as cv for easy porting because it is planned to rename that import to simply cv in a future release of OpenCV.

if you can’t import cv2, the installation of the package must have failed.

python’s package index has a package called opencv-python, which is maintained by a volunteer and tracks official releases. you can install that with pip install opencv-python (or pip3 if you’re on linux).
