✨ Features
- Fast path for Scatter and Gather ops.
- Quantization API for quantizing model weights to Float16 or Uint8.
- TensorByte and TensorShort tensor types for quantization.
- Pad operator to support 'axes' input, 'TensorInt' input and 'wrap' mode.
- GeluFast op for tiny stories optimization.
- Tensor 'Reshape' method for changing shape without backend.
- Functional API for compiling models with torch-like syntax.
- Analytics reporting on model import.
📈 Improvements
- Reworked async API with awaitable methods on tensor readback.
- Reworked tensor allocation scheme.
- Renamed tensor fields and methods.
- Reworked model serialization to use flatbuffers.
- Random layers accept integer seed rather than float.
- Improved NonMaxSuppression inference drastically and added GPUCompute backend.
🔧 Bug Fixes
- Dispatch limit issues on Split operator.
- Optimization pass where Dense has transposed weights.
- Import settings for Resize op on opset 10.
- Links to external sources in docs.
- Edge cases in ScatterElements and GatherElements infer correctly.
- Conv operator going out of bounds on GPUCompute and GPUCommandBuffer.
⚡ API Changes
- Broken optimization pass for Dense > ScaleBias.
- ArrayTensorData class and methods.
- 'CreateWorker' method from model extensions.
- Mapping of param symbolic tensor dims to original names.
- Model API for adding inputs, constants, layers to model (in favour of Functional API).
- Ops for tensor operations (in favour of Functional API).
