As you can see my graphics card ( GeForce GTX 1050 Ti) is listed on that Wikipedia page. Now search for your graphics card model name (in my case GTX 1050 Ti) on this page. System Requirement to build OpenCV with Cuda windowsīefore you start to build OpenCV with Cuda for windows, make sure you have NVIDIA graphics in your system.

To install OpenCV GPU on windows we have to compile or build the source code of Opencv with CUDA, cuDNN, and Nvidia GPU. It’s easy to install OpenCV for GPU on the Linux machine but it is hard for Windows. Now if you are working on deep learning or video processing project like Object Detection, Social Distance detection, you will face lags in the output video ( less frame rate per second), you can fix this lag using GPU if your system has NVIDIA GPU (NVIDIA Graphics card). OpenCV library can be used for both CPU and GPU, but if you just install OpenCV by “pip” or “conda” command ( pip install opencv- python) it will use CPU as a backend by default.

It would be nice to explain how to fix the native environment.You must install OpenCV for GPU if your system allows you. cv2.so: undefined symbol: PyUnicode_FromString”. Thanks everyone… Oh, by the way this breaks non-venv cv2 and makes it throw “ImportError. your article is good for non-venv/native but does not work without linking with venvs. I am using venv wrapper and this solved my problem. NOTE that it is almost mandatory to create a virtual environment in order to properly install tensorflow, scipy and keras, and always a best practice. Ln -s /usr/local/lib/python3.6/site-packages/cv2/python-3.6/cv2.so cv2.so # Or just go to your home folder if not set a venv site-packages folder # Go to your virtual environments site-packages folder if previously set It is necessary to create a link to it # Go to the folder where OpenCV's native library is builtĬd /usr/local/lib/python3.6/site-packages/cv2/python-3.6 However, the library is not correctly linked. One final note… Followed all the procedure stated here: like below might work, in my opinion: cmake -D WITH_CUDA=ON -D CUDA_ARCH_BIN="5.3" -D CUDA_ARCH_PTX="" -D WITH_GSTREAMER=ON -D WITH_LIBV4L=ON -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D BUILD_EXAMPLES=ON -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=OFF -D OPENCV_EXTRA_MODULES_PATH=/home/nvidia/opencv_contrib-3.4.6/modules -D PYTHON3_EXECUTABLE=/home/nvidia/venv/bin/python PYTHON3_NUMPY_INCLUDE_DIRS=/home/nvidia/venv/lib/python3.6/site-packages/numpy/core/include/ BUILD_opencv_python3=yes -D PYTHON_PACKAGES_PATH=~/home/nvidia/venv/lib/python3.6/site-packages/ -D PYTHON_LIBRARY=/usr/lib/aarch64-linux-gnu/libpython3.6m.so. Though I would do a separate installation with cmake explicitly configured for use of a specific virtual environment. However, since you are using the default system wide installation that is coherent and supports both python2 and python3 with opencv you may go on with it, and otherwise you might manage to get the cv2.so mapping to work on itself. To make cv2 module available within virtual environment you could use symlink probably and create cv2.so file within the virtual environment folder. How to exclude opencv during the time of installation of nano OS with sdkmanager? Hi moderators how to make cv2 module (from the default image) available within the virtualenv environment ? (created with -system-site-packages) option I believe doing so will lose the H/W acceleration capabilities. Type "help", "copyright", "credits" or "license" for more information. This downgraded OpenCV version for me python3 However within a virtualenv ( created via virtualenv -p python3 env -system-site-packages), it was unable to import cv2 from the default image.ĭoing sudo apt-get install python3-opencv made cv2 available within the virtualenv, but it downgraded the openCV version as shown below. I already had OpenCV installed in the default image. I solved it by: sudo apt-get install python3-opencv
