Build OpenVINO™ Runtime for Windows systems

The software was validated on:

  • Microsoft Windows 10 (64-bit) with Visual Studio 2019

Table of content:

Software Requirements

  • CMake* 3.14 or higher
  • Microsoft* Visual Studio 2019, version 16.8 or later
  • (Optional) Intel® Graphics Driver for Windows* (30.0) driver package.
  • Python 3.7 or higher for OpenVINO Runtime Python API
  • Git for Windows*

Build Steps

  1. Clone submodules:
    git clone https://github.com/openvinotoolkit/openvino.git
    cd openvino
    git submodule update --init --recursive
  2. Create build directory:
    mkdir build && cd build

NOTE: By default, the build enables the Inference Engine GPU plugin to infer models on your Intel® Processor Graphics. This requires you to download and install the Intel® Graphics Driver for Windows (26.20) driver package before running the build. If you don't want to use the GPU plugin, use the -DENABLE_INTEL_GPU=OFF CMake build option and skip the installation of the Intel® Graphics Driver.

  1. In the build directory, run cmake to fetch project dependencies and generate a Visual Studio solution.

    For Microsoft* Visual Studio 2019 x64 architecture:

    cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_BUILD_TYPE=Release ..

    For Microsoft* Visual Studio 2019 ARM architecture:

    cmake -G "Visual Studio 16 2019" -A ARM -DCMAKE_BUILD_TYPE=Release ..

    For Microsoft* Visual Studio 2019 ARM64 architecture:

    cmake -G "Visual Studio 16 2019" -A ARM64 -DCMAKE_BUILD_TYPE=Release ..
  2. Build generated solution in Visual Studio or run cmake --build . --config Release --verbose -j8 to build from the command line. Note that this process may take some time.

  3. Before running the samples, add paths to the Threading Building Blocks (TBB) and OpenCV binaries used for the build to the %PATH% environment variable. By default, TBB binaries are downloaded by the CMake-based script to the <openvino_repo>/inference-engine/temp/tbb/bin folder, OpenCV binaries to the <openvino_repo>/inference-engine/temp/opencv_4.5.0/opencv/bin folder.

Additional Build Options

  • Internal JIT GEMM implementation is used by default.

  • Threading Building Blocks (TBB) is used by default. To build Inference Engine with OpenMP threading, set the -DTHREADING=OMP option.

  • Required versions of TBB and OpenCV packages are downloaded automatically by the CMake-based script. If you want to use the automatically-downloaded packages but you have already installed TBB or OpenCV packages configured in your environment, you may need to clean the TBBROOT and OpenCV_DIR environment variables before running the cmake command; otherwise they won't be downloaded and the build may fail if incompatible versions were installed.

  • If the CMake-based build script can not find and download the OpenCV package that is supported on your platform, or if you want to use a custom build of the OpenCV library, refer to the Use Custom OpenCV Builds section for details.

  • To switch off/on the CPU and GPU plugins, use the cmake options -DENABLE_INTEL_CPU=ON/OFF and -DENABLE_INTEL_GPU=ON/OFF respectively.

  • To build the OpenVINO Runtime Python API:

    1. First, install all additional packages (e.g., cython and opencv) listed in the src\bindings\python\src\compatibility\openvino\requirements-dev.txt file:
      pip install -r requirements-dev.txt
    2. Second, enable the -DENABLE_PYTHON=ON in the CMake (Step #4) option above. To specify an exact Python version, use the following options:
      -DPYTHON_EXECUTABLE="C:\Program Files\Python37\python.exe" ^
      -DPYTHON_LIBRARY="C:\Program Files\Python37\libs\python37.lib" ^
      -DPYTHON_INCLUDE_DIR="C:\Program Files\Python37\include"
    3. To build a wheel package (.whl), enable the -DENABLE_WHEEL=ON option in the CMake step above (Step 4):
    4. After the build process finishes, export the newly built Python libraries to the user environment variables:
      set PYTHONPATH=<openvino_repo>/bin/intel64/Release/python_api/python3.7;%PYTHONPATH%
      set OPENVINO_LIB_PATH=<openvino_repo>/bin/intel64/Release;%OPENVINO_LIB_PATH%
      
      or install the wheel with pip:
      pip install <openvino_repo>/build/wheel/openvino-2022.2.0-000-cp37-cp37-win_amd64.whl
      
  • OpenVINO runtime compilation options: -DENABLE_OV_ONNX_FRONTEND=ON enables the building of the ONNX importer.

Building Inference Engine with Ninja* Build System

call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Auxiliary\Build\vcvars64.bat"
cmake -G Ninja -Wno-dev -DCMAKE_BUILD_TYPE=Release ..
cmake --build . --config Release
