I faced this error after performing some changes on the code. Any advices?
lgraph = yolov2Layers([128 128 3],numClasses,Anchors,lgraph,'relu_6');
Error using yolov2Layers>iReplaceImageInputLayer (line 298)
Index exceeds the number of array elements (1).
Error in yolov2Layers (line 112)
lgraph = iReplaceImageInputLayer(lgraph,params.ImageSize);
function lgraph = iReplaceImageInputLayer(lgraph,imageSize)
% Replace input size in image input layer.
idx = arrayfun(@(x)isa(x,'nnet.cnn.layer.ImageInputLayer'),...
lgraph.Layers);
imageInputIdx = find(idx,1,'first');
imageInput = vision.internal.cnn.utils.updateImageLayerInputSize(...
lgraph.Layers(imageInputIdx), imageSize);
lgraph = replaceLayer(lgraph,lgraph.Layers(imageInputIdx).Name,...
imageInput);
% Validate that replaced layer does not cause any issue.
analysis = nnet.internal.cnn.analyzer.NetworkAnalyzer(lgraph);
analysis.applyConstraints();
if any(isnan(analysis.LayerAnalyzers(2,1).Outputs.Size{1}))
error(message('vision:yolo:InvalidLayerSize', ...
mat2str(analysis.LayerAnalyzers(2,1).Inputs.Size{1}),...
mat2str([analysis.LayerAnalyzers(2,1).Inputs.Size{1}(1:2),...
analysis.LayerAnalyzers(2,1).Learnables.Size{1}(3)])));
end
end

This error generally occurs when you access the index that is not present (or) more than the number of elements
For example,
A = [1,2,3,4,5,6];
If you try to access the 7th element of A, it gives this error including in bracket the actual number of elements in the array, which is 6 here
A(7)
Index exceeds the number of array elements (6).
