OpenCV location on Ubuntu

[snippsat]

Do you talk about opencv-python?
That package include all of what needed to use OpenCV.

Q: Do I need to install also OpenCV separately?

A: No, the packages are special wheel binary packages and they already contain statically built OpenCV binaries.

Location will be under site-packages with a folder cv2.
