Option 3 - Headless main modules package: pip install opencv-python-headless.

or you are using some other package (such as PyQt) than OpenCV to create your GUI. You should always use these packages if you do not use cv2.imshow et al.

This means that the packages avoid a heavy dependency chain to X11 libraries and you will have for example smaller Docker images as a result. These packages are smaller than the two other packages above because they do not contain any GUI functionality (not compiled with Qt / other GUI components). Packages for server (headless) environments (such as Docker, cloud environments etc.), no GUI library dependencies Option 2 - Full package (contains both main modules and contrib/extra modules): pip install opencv-contrib-python (check contrib/extra modules listing from OpenCV documentation)ī.Option 1 - Main modules package: pip install opencv-python.Packages for standard desktop environments (Windows, macOS, almost any GNU/Linux distribution) If you installed multiple different packages in the same environment, uninstall them all with pip uninstall and reinstall only one package.Ī. There is no plugin architecture: all the packages use the same namespace ( cv2). Do not install multiple different packages in the same environment. There are four different packages (see options 1, 2, 3 and 4 below) and you should SELECT ONLY ONE OF THEM. Select the correct package for your environment: For example Linux distributions ship usually with very old pip versions which cause a lot of unexpected problems especially with the manylinux format. Make sure that your pip version is up-to-date (19.3 is the minimum supported version): pip install -upgrade pip. cv2 module in the root of Python's site-packages), remove it before installation to avoid conflicts.
