TF Lite on Raspberry Pi 4b

[Simon Perales]

Hi all,

I've been trying to set up tflite on a Raspberry Pi 4b 8gb, with Raspbian Bullseye 32 bit. I followed the instructions on this page: https://github.com/Qengineering/TensorFlow_Lite_Pose_RPi_32-bits.

Versions:

g++ (Raspbian 10.2.1-6+rpi1) 10.2.1 20210110

Flatc - 23.1.21

These are the includes I use:

#include <stdio.h>
#include <opencv2/opencv.hpp>
#include <opencv2/dnn.hpp>
#include <opencv2/highgui.hpp>
#include <iostream>
#include <opencv2/core/ocl.hpp>
#include "tensorflow/lite/builtin_op_data.h"
#include "tensorflow/lite/interpreter.h"
#include "tensorflow/lite/kernels/register.h"
#include "tensorflow/lite/string_util.h"
#include "tensorflow/lite/model.h"
#include <cmath>

When I try to build, I get these errors:

 This continues with the same types of errors. 

I've found that I don't get these errors if I delete these includes:

#include "tensorflow/lite/kernels/register.h"

#include "tensorflow/lite/model.h"

From what I can find online, the people having similar problems are having these problems because they use an unsupported version of flatbuffers:

Thank you for your help,

Solved by using Flatbuffers 2.0.0
