Option 4 - Headless full package (contains both main modules and contrib/extra modules): pip install opencv-contrib-python-headless (check contrib/extra modules listing from OpenCV documentation)Īll packages contain Haar cascade files.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. If you have previous/other manually installed (= not installed via pip) version of OpenCV installed (e.g.

This is derivative work from p圓, a site that previously tracked general compatibility with Python 3, which in turn was a derivative of, a site that tracks which Python distributions ship the wheel distribution.Pre-built CPU-only OpenCV packages for Python.Ĭheck the manual build section if you wish to compile the bindings from source to enable additional modules such as CUDA. We look for the Programming Language :: Python :: 3.10 classifier on the latest release of the project, via PyPI's JSON API. Or fork it, and send a pull request to help move the project towards Python 3.10 support, by adding the classifier and ensuring the project is tested against Python 3.10. If you are user of the package, send a friendly note to the package maintainer. If you are not able to give the time needed, please seek for help from the community. If you are package maintainer, it's time to start supporting Python 3.10.

There can be many reasons a package is not explicitly supporting Python 3.10:

100 white packages (27.8%) don't explicitly support Python 3.10 yet.

260 green packages (72.2%) support Python 3.10.
