tfjs-react-native-v0.1.0-alpha.2

We are very excited to announce the alpha release of TensorFlow.js for React Native. This brings all tensorflow.js capabilities to native apps written in react native. You can install the package from npm and setup instructions are also available on GitHub.

This platform package:

• Supports both inference and training.
• Has GPU support with WebGL via expo-gl.
• Has support for loading models from the web, AsyncStorage, and models that are included in the app bundle.
• Has support for saving models to AsyncStorage.

We welcome your feedback to help shape priorities for the general launch of this package. We also welcome developers familiar with React Native who are interested in getting involved in the future development of this library.

Looking forward to seeing what you build!

1.0.0

TensorFlow.js 1.0

TensorFlow.js 1.0 has been released!

With this release, we are aiming to have API stability guarantees and performance wins. For the most part, the breaking changes listed here are minor and should be relatively simple to migrate to new APIs.

Performance

TensorFlow.js 1.0 brings major performance gains on common machine learning models. Here is a graph of the performance gains of TensorFlow.js 1.0 versus last year in June 2018:

Features

• Tensor.array() and Tensor.arraySync() have been added. These are similar to Tensor.data() but return deeply nested arrays with the same logical shape as the original tf.Tensor.

Breaking changes

• Graphs converted from TensorFlow now generate JSON graphs (model.json). Any protocol buffer graphs with the extension .pb are now deprecated. You can convert .pb graphs to .json graphs with the pb2json NPM script in the tensorflow/tfjs-converter repository.
• tf.loadModel is deleted. Please use tf.loadLayersModel instead.
• tf.loadFrozenModel is deleted. Please use tf.loadGraphModel instead.
• tf.Model has been renamed tf.LayersModel.
• tf.FrozenModel has been renamed tf.GraphModel.
• When converting models with the tensorflowjs pip package, use --output_format strings tfjs_layers_model and tfjs_graph_model instead and tensorflowjs.
• Tensor.get is deleted. Please use Tensor.array and native array indexing instead.
• Tensor.buffer is now async (returns a Promise). If you need the sync version, please use Tensor.bufferSync.
• tf.fromPixels is deleted. Please use tf.browser.fromPixels instead.
• tf.toPixels is deleted. Please use tf.browser.toPixels instead.
• tf.batchNormalization is deprecated. Please use tf.batchNorm. Note the positional change of the arguments.
• Dataset.forEach is deleted. Please use DataSet.forEachAsync instead.
• LayersModel.fitDataset now only accepts {xs, ys} as a dictionary mapping 'xs' and 'ys' to their respective Tensor values. The [xs, ys] tuple format is now removed.
• tf.io.browserHTTPRequest now takes two arguments, a url and an options object. See the new API here.
• tf.data.generator() now takes a generator function*, instead of an iterator. See API doc.

0.15.3

High-level additions

TensorFlow.js 1.0 will be released during the TensorFlow dev summit on March 6th, 2019. With this release, we introduce some minor breaking API changes. If you are curious about this release, you can use the pre-release, version 1.0.0@next.

0.15.3 has both the new API and the old APIs. If you update to this version, you will get warning messages for methods that are deprecated which will point you to the new methods. If you migrate and get rid of the warnings in your code, you will be 1.0 ready.

Deprecated methods that will be removed in 1.0

• tf.loadModel is deprecated. Please use tf.loadLayersModel instead.
• tf.loadFrozenModel is deprecated. Please use tf.loadGraphModel instead.
• Tensor.get is deprecated. Please use Tensor.array and native array indexing instead.
• Tensor.buffer is now async (returns a Promise). If you need the sync version, please use Tensor.bufferSync.
• tf.fromPixels is deprecated. Please use tf.browser.fromPixels instead.
• tf.toPixels is deprecated. Please use tf.browser.toPixels instead.
• tf.batchNormalization is deprecated. Please use tf.batchNorm. Note the positional change of the arguments.
• Dataset.forEach is deprecated. Please use DataSet.forEachAsync instead.

New API

• Tensor.array() and Tensor.arraySync() are added which return a deeply nested array (rather than a flat array like Tensor.data()).
