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).
