Error during training phase

Hallo! I have a code:

nndata=[nndata;testdata1];
nnlabels=[traininglabels; testinglabels];
inputs = nndata';
targets = nnlabels';  
hiddenLayerSize = 25;
netx = patternnet(hiddenLayerSize);
netx.divideParam.trainRatio = 70/100;
netx.divideParam.valRatio = 15/100;
netx.divideParam.testRatio = 15/100;
netx.trainFcn='trainlm';
[netx,tr]=train(netx,inputs,targets);

I am getting the error as:

??? Undefined function or method 'eq' for input arguments of type 'network'.

Error in ==> C:\Programmi\MATLAB\R2011a\toolbox\prtools\@dataset\subsref.p>subsref at 23

Error in ==> automa at 169 net=train(netx,inputs,targets);

This code, with a different computer, runs with no errors. Can someone help me understand what may be the cause? can anyone help me find a solution? Thank you in advance.

That could happen if for some reason it thought "train" was the name of a matrix, such as if the NN code was not installed (or the installation was corrupt.)

Try

which -all train

to see what that system thinks "train" is.

thanks Walter.

MATLAB's response is:

which -all train

train is a variable.
C:\Programmi\MATLAB\R2011a\toolbox\nnet\nnet\@network\train.m  % Shadowed network method

I think you're right...

load trained.mat

clear cam

load trainedmodel.mat

cam=webcam();

%cam = ipcam("http://192.168.1.10:8080/video");

while 1

I=cam.snapshot;

I = imresize(I,[224,224]);

[bboxes,scores] = detect(detector,I);

if isempty(bboxes)

imshow(I)

title('no Mask')

drawnow

p='No Mask kindly wear to protect yourself';

NET.addAssembly('System,Speech');

ss = System.Speech.Synthesis.SpeechSynthesizer;

ss.volume = 100;

%Speak(ss, caUserInput)

Speak(ss, p)

else

I = insertObjectAnnotation(I, 'rectangle',bboxes,scores);

imshow(I)

title("Mask Detected")

drawnow

p='you are wearing mask thanks';

NET.addAssembly('System.Speech');

ss = System.Speech.Synthesis.SpeechSynthesizer;

ss.volume = 100.

%Speak((ss, caUserInput)

Speak(ss, p)

end

end

Error using load

Unable to read file 'trainedmodel.mat'. No such file or directory.
