SDB:Install OpenVINO

Jump to: navigation, search

OpenVINOā„¢ is an open-source toolkit for optimizing and deploying AI inference.
  • Boost deep learning performance in computer vision, automatic speech recognition, natural language processing and other common tasks
  • Use models trained with popular frameworks like TensorFlow, PyTorch and more
  • Reduce resource demands and efficiently deploy on a range of IntelĀ® platforms from edge to cloud

This open-source version includes several components: namely Model Optimizer, OpenVINOā„¢ Runtime, Post-Training Optimization Tool, as well as CPU, GPU, GNA, multi device and heterogeneous plugins to accelerate deep learning inference on IntelĀ® CPUs and IntelĀ® Processor Graphics. It supports pre-trained models from Open Model Zoo, along with 100+ open source and public models in popular formats such as TensorFlow, ONNX, PaddlePaddle, MXNet, Caffe, Kaldi.

Package Requirements

Important notes about Python: Python version 3.10 was used as a base. Therefore, to guarantee full functionality of this document, I suggest using the same version. But this is not mandatory..

Install CMake*, pkg-config and GNU* Dev Tools to build samples. Although the CMake and pkg-config build tools are not required by OpenVINO tools and toolkits, many examples are provided as CMake projects and require CMake to build them. In some cases, pkg-config is necessary to find the libraries needed to complete the application build.

Intel compilers leverage existing GNU build toolchains to provide a complete C/C++ development environment. If your Linux distribution does not include the full set of GNU development tools, you will need to install these tools. To install CMake, pkg-config, opencl, and the GNU development tools on your Linux system, open a terminal session and enter the following commands:

$ sudo zypper update
$ sudo zypper --non-interactive install cmake pkg-config \
                                        patterns-devel-C-C++-devel_C_C++ \
                                        opencl-headers ocl-icd-devel opencv-devel \
                                        pugixml-devel patchelf opencl-cpp-headers \
                                        python311-devel ccache nlohmann_json-devel \
                                        ninja scons git  git-lfs patchelf fdupes \
                                        rpm-build ShellCheck tbb-devel libva-devel \
                                        snappy-devel ocl-icd-devel \
                                        opencl-cpp-headers opencl-headers \
                                        zlib-devel gflags-devel-static \

Verify the installation by displaying the installation location with this command:

$ which cmake pkg-config make gcc g++

One or more of these locations will display:


Compiling from sources (.rpm coming soon).

We will begin compiling OpenVINO using source codes extracted directly from GitHub (RPM packages available soon). As a member of openSUSE and Intel Edge Innovator, I am taking the individual initiative of the packaging process and the publication of rpm packages for the openSUSE Linux platform. Thus, soon it will be possible to perform the installation solely through the zypper command.

Download: Github Instruction

Below are the commands to download version 2023.1 (latest release on the date of publication of this text):

$ git clone -b 2023.1.0
$ cd openvino && git submodule update --init --recursive

Install python dependency for building python wheels

$ python3 -m pip install -U pip 
$ python3 -m pip install -r ./src/bindings/python/src/compatibility/openvino/requirements-dev.txt
$ python3 -m pip install -r ./src/bindings/python/wheel/requirements-dev.txt

Now we will compile and install openvino with the instructions below:

$ mkdir build && mkdir openvino_dist && cd build

$ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../openvino_dist  \
        -DPYTHON_EXECUTABLE=`which python3.10` \
        -DPYTHON_LIBRARY=/usr/lib64/ \
        -DPYTHON_INCLUDE_DIR=/usr/include/python3.10 ..
$ make --jobs=$(nproc --all)
$ make install

Install built python wheel for OpenVINO runtime and OpenVINO-dev tools

python3 -m pip install openvino-dev --find-links ../openvino_dist/tools

Quick test for built openvino runtime

OpenVINO environment

Now with OpenVino compiled and installed in the distribution folder, to test it we must initialize the OpenVino development environment with the command below:

# cd ../openvino_dist/
# source ./ 
[] OpenVINO environment initialized

Insert the omz path into the environmental variable.

export PATH=$PATH:/home/cabelo/.local/bin
export PYTHONPATH=$PYTHONPATH:<openvino_repo>/openvino/bin/intel64/Release/python/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<openvino_repo>/openvino/bin/intel64/Release/

Now, create model directory and install model optimizer dependency:

$ mkdir ~/ov_models
$ pip3 install onnx==1.11.0 protobuf==3.19.4 openvino-dev[pytorch]

Before carrying out the test, should we download model alexnet with the command below:

$ cd samples/python/hello_classification/
$ omz_downloader --name alexnet
