Key Updates

• Performance optimizations for Transformer models
  • GPT2 - Enable optimizations for Attention with Past State and Attention Mask
  • BERT - Improve EmbedLayerNormalization fusion coverage
• Quantization updates
  • Added new quantization operators: QLinearAdd, QAttention
  • Improved quantization performance for transformer based models on CPU
    • More graph fusion
    • Further optimization in MLAS kernel
    • Introduced pre-packing for constant Matrix B of DynamicQuantizeMatMul and Qattention
• New Python IOBinding APIs (bind_cpu_input, bind_output, copy_outputs_to_cpu) allow easier benchmarking
  • Users no longer need to allocate inputs and outputs on non-CPU devices using third-party allocators.
  • Users no longer need to copy inputs to non-CPU devices; ORT handles the copy.
  • Users can now use copy_outputs_to_cpu to copy outputs from non-CPU devices to CPU for verification.
• CUDA support for Einsum (opset12)
• ONNX Runtime Training updates
  • Opset 12 support
  • New sample for training experiment using Huggingface GPT-2.
    • Upgraded docker image built from the latest PyTorch release
• Telemetry is now enabled by default for Python packages and Github release zip files (C API); see more details on what/how telemetry is collected in ORT
• [Coming soon] Availability of Python package for ONNX Runtime 1.4 for Jetpack 4.4
