Release Notes for onert-micro 2.0.0

Operations updated

• New ops supported : Cast, Ceil, Elu, Fill
• New CMSIS NN accelerated ops : SVDF, Relu, Relu6

New features for on-device training

  --fuse_add_to_fullyconnected_bias, --fuse_mul_to_fullyconnected_weights,
  --fuse_mul_with_fullyconnected.
• Add more optimization: CanonicalizePass.

Release Note 1.28.0

ONE Runtime

Python API

• Support experimental python API
  • Refer howto document for more details

On-device Training

• Support on-device training with circle model
  • Training parameter can be passed to onert via onert`s experimental API or loading new model format including training information: circle_plus
  • Trained model can be exported to circle model via experimental API nnfw_train_export_circle
  • Supporting Transfer learning from a pre-trained circle model
• Introduce circle_plus_gen tool
  • Generates a circle_plus model file with a given training hyperparameters
  • Shows a _circle_plus model details

Runtime configuration API

• onert supports runtime configuration API for prepare and execution phase via experimental APIs
  • nnfw_set_prepare_config sets configuration for prepare phase, and nnfw_reset_prepare_config resets it to default value
  • nnfw_set_execution_config sets configuration for execution phase, and nnfw_reset_execution_config resets it to default value
  • Supporting prepare phase configuration: prepare execution time profile
  • Supporting execution phase configuration: dump minmax data, dump execution trace, dump execution time
• Introduce new API to set onert workspace directory: nnfw_set_workspace
  • onert workspace directory is used to store intermediate files during prepare and execution phase

Minmax Recorder

• Now onert's minmax recorder dumps raw file format instead of HDF5 format
• onert dumps minmax data into workspace directory

On-device Compilation

• onert supports full quantization of uint8/int16 type weight and activation.
  • To quantize activation, onert requires minmax data of activation.
• onert supports on-device code generation for special backend requiring special binary format such as DSP, NPU.
  • Introduce new experimental API for code generation: nnfw_codegen

Type-aware model I/O usage

• If loaded model is quantized model, onert allows float type I/O buffer
  • onert converts float type input buffer to quantized type internally
  • onert fills float type output buffers by converting quantized type output data to float type internally
• On multimodel package, onert allows edges between quantized model and float type model

Release Note 1.27.2

ONE Compiler

• Update man pages of one-cmds tools.

Release Note 1.27.1

ONE Compiler

• Command schema supports multiple names.
• Fix invalid warning on boolean type option in onecc.
