Detecting Traffic lights using machine learning

Hello everyone. I am new matlab learner and working on a project to detect traffic lights using machine learning. In the first portion of my code i have this line "pkg load image". When i execute the code, matlab showing me error in this line and as a new learner i don't understand what is it. Please help me with this. here i am attaching the code below-

%% This script will detect traffic ligth's color %% in an infinitive loop. %% %% Author: Tomasz Ceszke 2017

%% ----------- init clear ; close all; more off pkg load image;

source('conf/settings.m'); source('lib/features.m'); source('lib/log_reg.m');

%% ----------- load learned factors load 'theta.mat';

%% ----------- settings live_image_path = strcat(datasource_path_prefix,'live/scene.png');

%% fprintf('Path to detect: %s \n\n',live_image_path); while 1 pause(1); try live_image = imread(live_image_path); catch disp('No image'); continue; end

X = zeros(1,numel(live_image));
X = reshape(double(rgb2gray(live_image)),1,[]);
if normalization    
  X = normalize(X,0);
end
[r h] = recognize(theta,X);
if r==1 
  color = 'GREEN';
else
  color = 'RED';
end
fprintf('%s h(x)=%.2f\n',color,h)
end
