Guide to build OpenCV from Source with GPU support (CUDA and cuDNN)

Guide to build OpenCV from source with GPU support (CUDA and cuDNN)

Feb 22nd, 2022

System specification

  • Operating system: Ubuntu 20.04 x84_64 (64-bit)
  • Architecture: amd64
  • GPU: NVIDIA GeForce RTX 3090
  • Python 3.8

Install dependencies and recommeneded packages

  • Uninstall built OpenCV (if there is a built installation of opencv already)

  • Update and upgrade your system

    $ sudo apt update
    $ sudo apt upgrade
  • Required packages

    $ sudo apt-get install build-essential cmake pkg-config unzip yasm git checkinstall  # generic tools
    $ sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev  # required
  • Python dependencies

    $ sudo apt-get install python3-dev python3-numpy python3-pip
    $ sudo apt install python3-testresources
  • Image I/O

    $ sudo apt-get install libjpeg-dev libpng-dev libtiff-dev
  • Video and audio

    $ sudo apt install libavcodec-dev libavformat-dev libswscale-dev libavresample-dev
    $ sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
    $ sudo apt install libxvidcore-dev x264 libx264-dev libfaac-dev libmp3lame-dev libtheora-dev 
    $ sudo apt install libfaac-dev libmp3lame-dev libvorbis-dev

    $ python3 -m pip uninstall opencv-python-headless
  • Remove python3-opencv or add -D HAVE_opencv_python3=ON to CMake Cofiguration

    $ sudo apt-get remove python3-opencv

Clone OpenCV and OpenCV Contrib

$ cd ~

download opencv with git repository

$ git clone https://github.com/opencv/opencv.git
$ git clone https://github.com/opencv/opencv_contrib.git
$ cd ~/opencv
$ git checkout <opencv-version>
$ cd ~/opencv_contrib
$ git checkout <opencv-version>

or with archive packages

$ wget -O opencv.zip https://github.com/opencv/opencv/archive/<version>.zip
$ wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/<version>.zip
$ unzip opencv.zip
$ unzip opencv_contrib.zip
$ mv opencv-<version> opencv  # rename
$ mv opencv_contrib-<version> opencv_contrib  # rename

Config OpenCV

$ mkdir opencv_build
$ cd opencv_build
  • Important: Check GPU Compute Capability to set CUDA_ARCH_BIN flag
  • NVIDIA GeForce RTX 3090 is 8.6
  • Note: OpenGL Dependencies
    • Following setup does not provide a proper way to enable OpenGL Support in OpenCV. However, OpenGL could still be used normally outside OpenCV. (Setup OpenGL for Ubuntu 20.04)
    • Avoid using libgtkglext1 and libgtkglext1-dev packages to enable OpenGL Support. It helps CMake recognize OpenGL but causes compile error (OpenCV v4.x)!
  • Sample Configuration:
cmake -D CMAKE_BUILD_TYPE=Release \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules/ \
-D PYTHON3_EXECUTABLE=/usr/bin/python3 \
-D PYTHON3_INCLUDE_DIR=/usr/include/python3.8/ \
-D PYTHON3_INCLUDE_DIR2=/usr/include/x86_64-linux-gnu/python3.8/ \
-D PYTHON3_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.8.so \
-D PYTHON3_NUMPY_INCLUDE_DIRS=/usr/lib/python3/dist-packages/numpy/core/include/ \
-D OPENCV_GENERATE_PKGCONFIG=ON \
-D OPENCV_PC_FILE_NAME=opencv.pc \
-D WITH_CUDA=ON \
-D WITH_CUDNN=ON \
-D OPENCV_DNN_CUDA=ON \
-D CUDA_ARCH_BIN=8.6 \
-D ENABLE_FAST_MATH=ON \
-D CUDA_FAST_MATH=ON \
-D WITH_CUFFT=ON \
-D WITH_CUBLAS=ON \
-D WITH_V4L=ON \
-D WITH_OPENCL=ON \
-D WITH_OPENGL=ON \
-D WITH_GSTREAMER=ON \
-D WITH_TBB=ON ../opencv
  • Check build-summary to have
NVIDIA CUDA:                   YES (ver <CUDA version>, CUFFT CUBLAS FAST_MATH)
    NVIDIA GPU arch:           <GPU Compute Capability>
    NVIDIA PTX archs:
 
cuDNN:                         YES (ver <cuDNN version>)

Build OpenCV

  • Check number of processors
    $ nproc
  • Compile
    $ make -j<number of processors>
  • Verify build
    $ ls bin
    $ ls lib
    $ ls OpenCVConfig*.cmake
    $ ls OpenCVModules.cmake

Install OpenCV

$ sudo make install
$ sudo /bin/bash -c 'echo "/usr/local/lib" >> /etc/ld.so.conf.d/opencv.conf'
$ sudo ldconfig

Verify OpenCV Installation

  • Check cv2 package
$ ls /usr/local/lib/python3.8/site-packages/cv2
  • Check cv2 module in Python:
import cv2
print(cv2.__version__)
print(cv2.getBuildInformation())
  • If ModuleNotFoundError: No module named 'cv2', check for existence of /usr/local/lib/python3.8/site-packages in python site.
$ python3 -m site
  • If /usr/local/lib/python3.8/site-packages was not included in the python path yet, add it permanently to the python path using PYTHONPATH variable
PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.8/site-packages
export PYTHONPATH
  • Add the script to either:
    • ~/.bashrc for user session usage
    • /etc/profile for system wide usage

Uninstall built OpenCV

$ cd ~/opencv_build
$ sudo make uninstall
$ cd ..
$ sudo rm -r opencv_build
  • Check for the removal that whether the import cv2 successful or not (using Python)
import cv2
print(cv2.__version__) #if successfully imported
  • Careful: Make sure to remove all relevant files in
    • /usr/local
    • /usr/local/bin
    • /usr/local/lib
    • /usr/local/cmake/opencv4
    • /usr/local/include/opencv4
    • /usr/local/share/opencv4
    • /usr/local/lib/python3.8/dist-packages/cv2
    • /usr/local/lib/python3.8/site-packages/cv2
$ sudo find /usr/local -name "*opencv*" -exec rm -i {} \;
$ sudo find /usr/local -name "*cv2*" -exec rm -i {} \;
