error while running graph=layerGraph(net)

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.

[Tan]

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'}

[Tan]

so how should i solve this?

[Walter Roberson]

By now, R2023a, googlenet() returns DAGNetwork and the R2023a layerGraph() is happy with it.

In R2020b, googlenet() is documented as returning DAGNetwork and the error message implies layerGraph in that version should accept it.

[Tan]

thanks a lot!

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