The interpreter uses a static graph ordering and a custom (less-dynamic) memory allocator to ensure minimal load, initialization, and execution latency. We will start by initializing an Interpreter instance with our model. Then we can use that converted file in the mobile application. The TensorFlow Lite source tree contains a header file with the name "string. For example, if a model takes only one input and returns only one output: try (Interpreter interpreter = new Interpreter(file_of_a_tensorflowlite_model)) { interpreter. TFLiteConverter. The TensorFlow Lite interpreter is a library that takes a model file, executes the operations it defines on input data and provides access to the output. TensorFlow Lite has a new mobile-optimized interpreter, which has the key goals of keeping apps lean and fast. Those modules can not only define new functions but also new object types and their methods. The interface provided by this class is experimenal and therefore not exposed: as part of the public API. 编译TensorFlow Lite要达到这么个目标:只要写一份app代码就可跨平台运行在Windows、iOS、Andorid,而且编写、调试app主要是在用Visual Studio,一旦Windows通过,基本就可认为iOS、Android也没问题了。.
