Hi Farhâd,
I have built from source OpenVINO™ 2022.1 on Raspberry Pi. I'm sharing the steps below:
1. Setting up build environment.
sudo apt update && sudo apt upgrade -y
sudo apt install build-essential
2. Installing Cmake from source
Fetch CMake from the Kitware* GitHub* release page, extract it, and enter the extracted folder:
cd ~/
wget https://github.com/Kitware/CMake/releases/download/v3.18.4/cmake-3.18.4.tar.gz
tar xvzf cmake-3.18.4.tar.gz
cd ~/cmake-3.18.4
Run the bootstrap script to install additional dependencies and begin the build:
./bootstrap
make -j4
sudo make install
3. Installing OpenCV from source
Install the following packages :
sudo apt install git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev libatlas-base-dev python3-scipy
Clone the repository from OpenCV* GitHub page, prepare the build environment, and build:
cd ~/
git clone --depth 1 --branch 4.5.5-openvino-2022.1.0 https://github.com/opencv/opencv.git
cd opencv && mkdir build && cd build
cmake –DCMAKE_BUILD_TYPE=Release –DCMAKE_INSTALL_PREFIX=/usr/local ..
make -j4
sudo make install
4. Downloading source code and installing dependencies
The open-source version of Intel® OpenVINO™ toolkit is available through GitHub. The repository folder is titled openvino.
cd ~/
git clone --depth 1 --branch 2022.1.0 https://github.com/openvinotoolkit/openvino.git
Fetch the submodules from the repository:
cd ~/openvino
git submodule update --init --recursive
Run the script to install the dependencies for Intel® OpenVINO™ toolkit:
sh ./install_build_dependencies.sh
5. Building
The first step to beginning the build is telling the system where the installation of OpenCV is. Use the following command:
export OpenCV_DIR=/usr/local/lib/cmake/opencv4
To build the Python API wrapper, install all additional packages:
cd ~/openvino/samples/python/
pip3 install -r requirements.txt
The toolkit uses a CMake building system to guide and simplify the building process. To build both the inference engine and the MYRIAD plugin for Intel® Neural Compute Stick 2, use the following commands. Remove all the backslashes (\) when running the commands below. The backslashes are used to inform that these commands are not separated.
cd ~/openvino
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=/home/pi/openvino_dist \
-DENABLE_MKL_DNN=OFF \
-DENABLE_CLDNN=OFF \
-DENABLE_GNA=OFF \
-DENABLE_SSE42=OFF \
-DTHREADING=SEQ \
-DENABLE_OPENCV=OFF \
-DNGRAPH_PYTHON_BUILD_ENABLE=ON \
-DNGRAPH_ONNX_IMPORT_ENABLE=ON \
-DENABLE_PYTHON=ON \
-DPYTHON_EXECUTABLE=$(which python3.7) \
-DPYTHON_LIBRARY=/usr/lib/arm-linux-gnueabihf/libpython3.7m.so \
-DPYTHON_INCLUDE_DIR=/usr/include/python3.7 \
-DCMAKE_CXX_FLAGS=-latomic ..
make -j4
sudo make install
For your information, I have validated these steps on Raspbian Buster 32-bit. Only Raspbian Buster 32-bit and Raspbian Stretch 32-bit are validated on OpenVINO™. We apologize for the inconvenience and will inform the relevant team to update the guide.
To uninstall your previous OpenCV build, run the command sudo make uninstall from your OpenCV 4.5.2-openvino build directory. You can refer here for more information.
Regards,
Megat
