Opencv python by opencv
Automated CI toolchain to produce precompiled opencv-python, opencv-python-headless, opencv-contrib-python and opencv-contrib-python-headless packages.
About Opencv python
From the project's README at github.com/opencv/opencv-python. Lightly cleaned for readability; for the full source see the upstream repo.
Check the manual build section if you wish to compile the bindings from source to enable additional modules such as CUDA. Installation and Usage
1. If you have previous/other manually installed (= not installed via ``) version of OpenCV installed (e.g. cv2 module in the root of Python's site-packages), remove it before installation to avoid conflicts. 2. Make sure that your version is up-to-date (19.3 is the minimum supported version): . Check version with . For example Linux distributions ship usually with very old versions which cause a lot of unexpected problems especially with the format. 3. Select the correct package for your environment:
There are four different packages (see options 1, 2, 3 and 4 below) and you should SELECT ONLY ONE OF THEM. Do not install multiple different packages in the same environment. There is no plugin architecture: all the packages use the same namespace (). If you installed multiple different packages in the same environment, uninstall them all with `` and reinstall only one package.
