The test programs allowing to test the model before deploying it to the target processor can be found in the TensorFlow Lite Micro repository

Arduino

For the Arduino SDK (Software Development Kit) you can install the TensorFlowLite_ESP32 library, which does not only contain the TensforFlowLite library but also the examples

The Hello World test programs

Three test programs are available:

hello_world_test.cc
evaluate.py
evaluate_test.py

These programs are built using the bazel

build tool. In order tto build hello_world_test.cc, got to the base directory of TensorFlow Lite Micro directory and enter the commands. First the hello_world_test binary must be built from its source:

before the program can be run:

For a detailed analysis of the test program please set analysis cc test

The Hello World application with esp-idf

Let's start with the hello_world example. This example uses a pre-built model that has gone through the training process and it has been quantized to reduce its size such that it can be loaded into the small micro-controller memory. Building, training and quantization is described at https://github.com/tensorflow/tflite-micro/tree/main/tensorflow/lite/micro/examples/hello_world.
