What's new in Sentis 1.4.0-pre.3

This is a summary of the changes from Sentis 1.3.0-pre.3 to Sentis 1.4.0-pre.3.

Added

Functional API for building and editing models using PyTorch style syntax. This includes operator overloads, sliced indexing with ranges and automatic type promotion.
Quantization API for compressing model weights by up to a factor of 4. Quantized models take up less space on disk and use less memory during inference.
Fast path for ScatterElements and GatherElements operations.
Resize operator is supported on all back ends with all tensor shapes, and supports axes parameter.
Pad operator supports integer tensors and wrap mode, and supports axes input tensor.
Docs pages and package samples for new features.

Model serialization now uses FlatBuffers rather than binary serialization. This will allow far greater backwards compatibility for models exported in versions of Sentis from 1.4 onwards.
Fixed many small importer and inference bugs for improved model compatibility.
Renamed methods on Tensor and IWorker for clarity and consistency.
Docs pages and package samples to be accurate to the new API.

Model API where inputs, constants and layers can be edited directly on a model. See the new functional API where you can build new models as well as adapt and extend existing models.
Ops for direct operations on tensors. See the new functional API where you can create models to perform optimized operations on tensors.
Custom ONNX layers can no longer be defined by users as they were not compatible with the new model serialization scheme. Custom import will be reworked for an upcoming release.

This is a summary of the changes from Sentis 1.3.0-pre.2 to Sentis 1.3.0-pre.3.

Updated Clip operator to support integer data type.
Fixed inference and compatibility issues for Resize, Dense, Split and NonZero operators.
Inspector improvements including horizontal scrolling and operating while out of focus.
Docstrings have been updated for accuracy and links to models in docs are fixed.

This is a summary of the changes from Sentis 1.2 to Sentis 1.3.0-pre.1 and 1.3.0-pre.2.

This is a summary of the changes from Sentis 1.1 to Sentis 1.2.

Support and improvement for LayerNormalization, Gelu, Resize1D, Upsample, OneHot operators.
Improvements for model import and saving to serialized assets.
Optimizations for models with ScalarMad layer and operator.

This is a summary of the changes from Sentis 1.0 to Sentis 1.1.

GPUPixel back end now supports TensorInts and many more operators.
Models can now be exported to StreamingAssets.
Interface for asynchronous readback of GPU tensors with callback.
Ops utility methods for float mathematics and getting and setting slices of tensors.

Improved compatibility for many operators including Conv, ConvTranspose and BatchNormalization.
Improved performance of many operators on GPUCompute and GPUCommandBuffer back ends.
Reduced allocation when executing worker.
Improved import times.
Improved shape and data type inference to optimize models better.
Inference accuracy fixes.

Sentis is the new name for the Barracuda package.

This is a summary of the changes from Barracuda 3.0 to Sentis 1.0.

For information on how to upgrade, refer to the Upgrade Guide.

You can now override model layers in your code, and add your own layers. Refer to the Add a custom layer example in the sample scripts for an example.

All the back end types have been optimized and improved so Sentis as a whole has better performance on both the GPU and the CPU.
The way Sentis represents tensors has changed to make Sentis compatible with more models, and make it easier to convert Python preprocessing code into C#. Refer to Tensor fundamentals and Do operations on tensors for more information.
Sentis supports more Open Neural Network Exchange (ONNX) operators. Refer to Supported ONNX operators for more information.
You can now import models larger than 2 gigabytes.
The Model Asset Import Settings window no longer contain contains Force Arbitrary Batch Size and Treat Errors as Warnings settings. The window also no longer contains an Open imported NN model as temp file button. Use Open instead.
