A place for frequently used python wheels that are not available out of the box
- Install the prerequisites:
sudo apt install build-essential
sudo apt install cmake git libgtk-3-dev libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libdc1394-22-dev
sudo apt install python3-dev python3-pip python3-numpy
- Install gstreamer:
sudo apt install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good \
gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc \
gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 \
gstreamer1.0-qt5 gstreamer1.0-pulseaudio
sudo apt install ubuntu-restricted-extras
sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
- Clone the project(s):
VERSION=4.4.0
git clone https://github.com/opencv/opencv.git -b $VERSION --depth 1
(optional: for contrib including non-free modules)
VERSION=4.4.0
git clone https://github.com/RidgeRun/opencv_contrib.git --depth 1
- Configure the build:
cd opencv
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D OPENCV_GENERATE_PKGCONFIG=ON \
-D BUILD_EXAMPLES=OFF \
-D INSTALL_PYTHON_EXAMPLES=OFF \
-D INSTALL_C_EXAMPLES=OFF \
-D PYTHON_EXECUTABLE=$(which python2) \
-D BUILD_opencv_python2=OFF \
-D PYTHON3_EXECUTABLE=$(which python3) \
-D PYTHON3_INCLUDE_DIR=$(python3 -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())") \
-D PYTHON3_PACKAGES_PATH=$(python3 -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())") \
-D WITH_GSTREAMER=ON \
-D WITH_CUDA=ON \
..
Note:(If you decide to build the contrib modules then set add
-D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules/in the above)
Note:For cudnn, use the appropriate path e.g.
-D CUDNN_LIBRARY=/usr/lib/cuda-10.1/targets/x86_64-linux/
Note: In case Openblas is not-detected, please follow the steps in opencv/opencv#12957
Here is a sample output of the above set-up process:
