  • Make '-werror' optional in CMake (#353)
  • Add description of commit message style to Contributing guide (#350)

Breaking API changes

  • PyTorch iterator returns exact number of samples per epoch, so last batch could be smaller if epoch size is not divisible by the batch size. To keep the old behavior when data is wrapped up use “stop_at_epoch” argument

Known issues:

  • New Video reader operator requires NVIDIA VIDEO CODEC SDK support in the platform. NVIDIA GPU Cloud (NGC) optimized containers lacks this functionality in the default configuration prior to 19.01. To enable it please run the container with the ‘video’ capability enabled, ie.:
    -e "NVIDIA_DRIVER_CAPABILITIES=compute,utility,video"
