Tensorflow to tensorflow lite. Check out this tutorial on how to deploy TensorFlow Models on any edge device, using the TensorFlow Lite and the IBM Watson Visual Recognition service. An on-device interpreter with kernels optimises faster execution on mobile. 0-5-armmp-lpae, Tensorflow armhfビルド用). Google is giving developers a way to add machine learning models to their mobile and embedded devices. Mit Tensorflow Lite veröffentlicht Google eine extrem kleine Variante seiner Machine-Learning-Bibliothek, die speziell für. TensorFlow Lite是一个用于将TensorFlow模型部署到移动、嵌入式、物联网设备上的低延迟,轻量推理框架。其特点如下: 为不同端上优化的核心operator的解释器(Interpreter)打包成一个轻量的二进制包; 丰富的平台支持。Android和iOS设备、嵌入式Linux、微控制器设备等;. It enables on-device machine learning inference with low latency and a small binary size. ML Kit can use TensorFlow Lite models only on devices running iOS 9 and newer.
