There are two methods of getting OpenCV sources: After successful build you will find libraries in the build/lib directory and executables (test, samples, apps) in the build/bin directory: CMake package files will be located in the build root: By default OpenCV will be installed to the /usr/local directory, all files will be copied to following locations: Since /usr/local is owned by the root user, the installation should be performed with elevated privileges (sudo): Installation root directory can be changed with CMAKE_INSTALL_PREFIX configuration parameter, e.g. He specializes in Windows, macOS, Android, iOS, and Linux platforms. Hit Configure for the final configuration round. Get other third-party dependencies: libraries with extra functionality like decoding videos or showing GUI elements; libraries providing optimized implementations of selected algorithms; tools used for documentation generation and other extras. here. Go to windows menu, find the Linux distribution you installed and run it. Note that the path separator in OPENCV_EXTRA_MODULES_PATH (or any other parameter value) has to be "/" and not "\". Check that the libraries installed by your build are not causing the import error. To name the few more available libraries that can be included with the following linker flags You can type groups command in a terminal window after This "tutorial" is done with a standard Python install, from the Python website with no virtual environment. If they do your Python installation can successfully access OpenCV.
