Added

Changed

  • AMD Clang is now the default CXX and C compiler.
  • Added webdataset reader support to rocAL.

Removed

Optimizations

Resolved issues

Known issues

  • The package installation requires manual installation of TurboJPEG 
    git clone -b 3.0.2 https://github.com/libjpeg-turbo/libjpeg-turbo.git
mkdir tj-build && cd tj-build
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=RELEASE -DENABLE_STATIC=FALSE -DCMAKE_INSTALL_DEFAULT_LIBDIR=lib -DWITH_JPEG8=TRUE ../libjpeg-turbo/
make -j8 && sudo make install
  • CentOS/RedHat/SLES requires additional the manual installation of the FFMPEG Dev package
  • Hardware decode requires installing ROCm with the graphics usecase

Upcoming changes

rocAL 2.1.0 for ROCm 6.3.0

Added

  • rocAL Pybind support for package installation has been added. To use the rocAL python module, set the PYTHONPATH: export PYTHONPATH=/opt/rocm/lib:$PYTHONPATH
  • Last batch policy, pad last batch, stick to shard, and shard size support have been added for the coco, caffe, caffe2, mxnet, tf, and cifar10 image readers.

Changed

  • rocdecode installation disabled when running the setup script.

Removed

  • rocDecode dependencies for package install has been removed.

  • Test failures have been fixed

Known issues

  • The package installation requires the manual installation of TurboJPEG and RapidJSON.
  • CentOS/RedHat/SLES requires additional the manual installation of the FFMPEG Dev package.
  • Hardware decode requires installing ROCm with the graphics usecase.

Upcoming changes

rocAL 2.0.0 for ROCm 6.2.1

Changes

  • The new version of rocAL introduces many new features, but does not modify any of the existing public API functions.However, the version number was incremented from 1.3 to 2.0. Applications linked to version 1.3 must be recompiled to link against version 2.0.

  • Added Python support for audio decoders.
  • Added Pytorch iterator for audio.
  • Added Python audio unit test and support to verify outputs.
  • Added rocDecode for HW decode.
  • Added support for:
    • Audio loader and decoder, which uses libsndfile library to decode wav files
    • Audio augmentation - PreEmphasis filter, Spectrogram, ToDecibels, Resample, NonSilentRegionDetection. MelFilterBank
    • Generic augmentation - Slice, Normalize
    • Reading from file lists in file reader
    • Downmixing audio channels during decoding
    • TensorTensorAdd and TensorScalarMultiply operations
    • Uniform and Normal distribution nodes
  • Image to tensor updates
  • ROCm install - use case graphics removed

Known issues

  • Dependencies are not installed with the rocAL package installer. Dependencies must be installed with the prerequisite setup script provided. See the rocAL README on GitHub for details.
