v2.0.2a1

Release 2.0.2a1

LiteRT

Major Features and Improvements

Breaking Changes

• com.google.ai.edge.litert.TensorBufferRequirements
  • It becomes a data class, so all fields could be accessed directly without getter methods.
  • The type of field strides changes from IntArry to List<Int> to be immutable.
• com.google.ai.edge.litert.Layout
  • The type of field dimensions and strides changes from IntArry to List<Int> to be immutable.
• Rename GPU option NoImmutableExternalTensorsMode to NoExternalTensorsMode

Known Caveats

Major Features and Improvements

• [tflite] Add error detection in TfLiteRegistration::init(). When a Delegate
  kernel returns TfLiteKernelInitFailed(), it is treated
  as a critical failure on Delegate. This error will be detected in
  SubGraph::ReplaceNodeSubsetsWithDelegateKernels() will cause
  Delegate::Prepare() to fail, ultimately leading
  InterpreterBuilder::operator() or Interpreter::ModifyGraphWithDelegate() to
  return an error.
• Added Profiler API in Compiled Model: source.
• Added Error reporter API in Compiled Model: source.
• Added resize input tensor API in Compiled Model: source.

Bug Fixes and Other Changes

• The Android minSdkVersion has increased to 23.
• Update tests to provide kLiteRtHwAcceleratorNpu for fully AOT compiled
  models.
