![]() ![]() can be used as a shortcut to the data folder. 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. Also added a non-linearity to zooming (starts slower).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. I.e., the bigger the tree the more you can zoom in. The maximum extent of zooming is now proportional to the number of tips in the tree. These include the reintroduction of font size spinners (in addition to font selection dialogs) and scrolling of the entire control panel when larger than the window. Numerous tweaks to the controls to make things more convenient.Colour schemes are now selectable for particular attributes and these are saved and loaded in FigTree files.The old interpolating colour scheme is still available. New colour scheme for continuous attributes also based on HSB.This replaces the old fixed sequence of colours and is more customizable. New colour scheme for discrete attributes based on a HSB colour wheel.Added a 'Legend' option which can produce a colour legend for any attribute/colour scheme being used.These can be coloured and sized by attributes. ![]()
