The AMD ROCm Augmentation Library (rocAL) is designed to efficiently decode and process images and videos from a variety of storage formats and modify them through a processing graph programmable by the user. rocAL currently provides C API. For more details, go to rocAL user guide page.

Build instructions

Prerequisites setup script for Linux - rocAL-setup.py

For the convenience of the developer, we here provide the setup script which will install all the dependencies required by this project.

NOTE: This script only needs to be executed once.

Prerequisites for running the script

• Linux distribution

  • Ubuntu - 20.04 / 22.04
  • CentOS - 7 / 8
  • RedHat - 8 / 9
  • SLES - 15-SP4

• ROCm supported hardware

• Install ROCm with --usecase=graphics,rocm

  usage:

  python rocAL-setup.py     --directory [setup directory - optional (default:~/)]
                            --opencv    [OpenCV Version - optional (default:4.6.0)]
                            --protobuf  [ProtoBuf Version - optional (default:3.12.4)]
                            --pybind11  [PyBind11 Version - optional (default:v2.10.4)]
                            --reinstall [Remove previous setup and reinstall (default:no)[options:yes/no]]
                            --backend   [rocAL Dependency Backend - optional (default:HIP) [options:OCL/HIP]]
                            --rocm_path [ROCm Installation Path - optional (default:/opt/rocm) - ROCm Installation Required]
  

  Note:

  • ROCm upgrade requires the setup script rerun.

Using rocAL-setup.py

• Install ROCm with --usecase=graphics,rocm

• Use the below commands to set up and build rocAL

  • Clone rocAL source code

  git clone https://github.com/ROCm/rocAL.git
  cd rocAL
  

  Note: rocAL supports CPU and two GPU backends: OPENCL/HIP:

  • Building rocAL with default HIP backend:

    • run the setup script to install all the dependencies required
    • run the below commands to build rocAL & test
    • run tests - test option instructions

    python rocAL-setup.py
    mkdir build-hip
    cd build-hip
    cmake ../
    make -j8
    sudo cmake --build . --target PyPackageInstall
    sudo make install
    make test

Note: sudo is required to build rocAL_pybind package (only supported on HIP backend)

Note:

• rocAL_pybind is not supported on OPENCL backend
• rocAL cannot be installed for both GPU backends in the same default folder (i.e., /opt/rocm/)
• if an app interested in installing rocAL with both GPU backends, then add -DCMAKE_INSTALL_PREFIX in the cmake commands to install rocAL with OPENCL and HIP backends into two separate custom folders.
