graph = layerGraph(net);
Error using layerGraph
lgraph = layerGraph(net);

Invalid argument at position 1. Input must be an array of layers, a SeriesNetwork, a DAGNetwork, or a dlnetwork.

So what's the question? Presumably your 'net' input is none of the the legal input types listed in the error message.

net = googlenet('Weights','none');
%lys = net.Layers;
%lys(end-3:end)
numClasses = numel(categories(imdsTrain.Labels));
lgraph = layerGraph(net);
after that it show
Error using layerGraph
lgraph= layerGraph(net);

Like I said, your 'net' is not one fo the types listed in the error message:
net = googlenet('Weights','none');
net =
LayerGraph with properties:
Layers: [144×1 nnet.cnn.layer.Layer]
Connections: [170×2 table]
InputNames: {'data'}
OutputNames: {'output'}

Why is a solution even required? You can see googlenet() is giving you a LayerGraph direcly, without the need for further manipulation.
