**Float16 inference**: a mode in which Float16 is used for inference. Float16, also called half-precision, uses 16 bits to represent a number.
## Available APIs
APIs involved in MindSpore Lite model inference are categorized into context APIs, model APIs, and tensor APIs.

Before moving to the main process, you need to reference related header files and compile functions to generate random input.

#include "mindspore/model.h"
// Generate random input.
int GenerateInputDataWithRandom(OH_AI_TensorHandleArray inputs) {
