The document below If not check if you have a "binding" folder in the Visual Studio solution. NOTICE: this action was created to support CI testings of cvui, a GUI library for OpenCV. You need to be aware of the implications of this since it is not normal Java behavior. Anaconda contains a variety of Python packages that are used in data science and machine learning. A superuser can use an Now you should be able to create a new annotation task. For CVAT version more than v2.1.0 its possible to pull specific version of Packages for Android, iOS and Windows built with default parameters and recent compilers are published for each release, they do not contain opencv_contrib modules. If you are interested in compiling the latest version of OpenCV (currently OpenCV 4.x.x) for ARM based SBCs or x86 computers then this project will show you how. See OpenCV configuration options reference for details. https://forums.developer.nvidia.com/t/compiling-opencv-on-jetpack-5/219668. 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. But in some cases, even if the module was successfully installed in your Python installation, you may end up with this message when importing OpenCV with import cv2: This case is detailed in the troubleshooting section and is almost entirely based on this quite extensive github issue. In production you will want to use a user and password with mjpg-streamer. Check in your environment variables that CUDA_PATH and CUDA_PATH_Vxx_x are here and pointing to your install path.
