Tensorflow-lite requires files that were not part of its installation

I am trying to use Tensorflow-lite to run inference on a video frame by frame. This is my code so far:

#include <iostream> #include "src/VideoProcessing.h" #include <cstdio> #include <opencv2/opencv.hpp> #include <opencv2/videoio.hpp> #include "tensorflow/lite/interpreter.h" #include "tensorflow/lite/kernels/register.h" #include "tensorflow/lite/model_builder.h" #include "tensorflow/lite/interpreter_builder.h" int main() { int fps = VideoProcessing::getFPS("trainer.mp4"); unsigned long size = VideoProcessing::getSize("trainer.mp4"); cv::VideoCapture cap("trainer.mp4"); //Check if input video exists if(!cap.isOpened()){ std::cout<<"Error opening video stream or file"<<std::endl; return -1; } //Create a window to show input video cv::namedWindow("input video", cv::WINDOW_NORMAL); //Keep playing video until video is completed while(true){ cv::Mat frame; //Capture frame by frame cap >> frame; //If frame is empty then break the loop if(frame.empty()){break;} //Show the current frame imshow("input video", frame); } //Close window after input video is completed cap.release(); //Destroy all the opened windows cv::destroyAllWindows(); std::cout << "Video file FPS: " << fps << std::endl; std::cout << "Video file size: " << size << std::endl; // Load the model std::unique_ptr<tflite::FlatBufferModel> model = tflite::FlatBufferModel::BuildFromFile("pose_landmark_full.tflite"); // Build the interpreter tflite::ops::builtin::BuiltinOpResolver resolver; std::unique_ptr<tflite::Interpreter> interpreter; tflite::InterpreterBuilder(*model, resolver)(&interpreter); if (interpreter == nullptr) { fprintf(stderr, "Failed to initiate the interpretern"); exit(-1); } return 0; } 

I use this command to run my project:

g++ -std=c++17 main.cpp src/VideoProcessing.cpp `pkg-config --libs --cflags opencv4` -o result 

My tensorflow-lite is in `/usr/local/include/tensorflow/lite/`. This is my output:
