Package Exports

react-native-tensorflow

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-native-tensorflow) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

react-native-tensorflow

A TensorFlow inference library for react native. It follows the android inference api from TensorFlow: https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/android

This library is currently only supporting android

Getting started

$ npm install react-native-tensorflow --save

Mostly automatic installation

$ react-native link react-native-tensorflow

Manual installation

iOS

In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
Go to node_modules ➜ react-native-tensorflow and add RNTensorflow.xcodeproj
In XCode, in the project navigator, select your project. Add libRNTensorflow.a to your project's Build Phases ➜ Link Binary With Libraries
Run your project (Cmd+R)<

Android

Open up android/app/src/main/java/[...]/MainActivity.java

Add import com.rntensorflow.RNTensorFlowPackage; to the imports at the top of the file
Add new RNTensorFlowPackage() to the list returned by the getPackages() method

Append the following lines to android/settings.gradle:

include ':react-native-tensorflow'
project(':react-native-tensorflow').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-tensorflow/android')

Insert the following lines inside the dependencies block in android/app/build.gradle:
```
compile project(':react-native-tensorflow')
```

Usage

First you need to put a model in the android/src/main/assets folder. Then you can create an instance providing the file name of the model. Next you will need to feed an image in the form of a number array. Then run the inference and lastly fetch the result.

import TensorFlowInference from 'react-native-tensorflow';


const tensorflowInference = new TensorFlowInference('tensorflow_inception_graph.pb')
tensorflowInference.feed('inputName', [1,2,3,4,...])
tensorflowInference.run('outputNames')
tensorflowInference.fetch('outputName', 10).then(output => console.log(output))
