+The example sketches include "tensorflow/lite/micro/micro_interpreter.h" which internally include "utility.h" header file when compiling examples for Arduino (when -DARDUINO flag is passed to the compiler). This header file does not exist in esp32-arduino core. Hence, keeping this file here as a workaround and including an alternate header file.
