Follow the instructions to complete the installation. This action downloads, compiles and installs OpenCV. The image above is a screenshot of a video frame that has been processed by Motion Detector. Note: Check that you are specifically using WSL2 backend Install developer tools used to compile OpenCV 3.0: Install libraries and packages used to read various image and video formats from disk: Install GTK so we can use OpenCVs GUI features: Install packages that are used to optimize various functions inside OpenCV, such as matrix operations: Install the Python 3.4+ headers and development files: The last step can also be done by hand using ccmake. Learn more. Double-click Docker.app in the Applications The problem is most likely linked to other libraries not loaded by Python even if they are in your PATH environment variables. the version (e.g. Specify these options in the You signed in with another tab or window. install it as well.

You can type groups command in a terminal window after The process is based on this tutorial by Anindya for the step-by-step process with CMake GUI and this tutorial by James Bowley for the process with command line CMake and some troubleshooting. For more information Official guide for docker WSL2 backend can be found To do this you can add manually the DLL files path to a script: This import should be done by default in the config.py file in the cv2 folder and should probably not solve the issue by itself. I'm running this on a test LAN and not securing mjpg-streamer. On ARM platforms with limited memory create a swap file or the build may fail enable integration with the Linux Distribution that you chose. install specific version (e.g v2.1.0, dev). then great!
