Can we plot the output of in-between layers in deep neural network?

I have a deep neural network having 297 layers. I want to visualize the output of some of the layers that are in-between this network for analysis purpose. Is it possible way to do that? Or should I create the network upto the layer where I want to take the output and plot the output using the 'plot' command?

You can access the intermediate activations of a network by setting the name-value argument, Outputs, in the predict call. See the following documentation page for examples on this syntax: https://uk.mathworks.com/help/deeplearning/ref/dlnetwork.predict.html#d126e63879. You can select 1 or many layers for which to extract these intermediate activations using this name-value argument.

No, you do not need to retrain the network. The command will just returned the intermediate activations of the network passed to the function on the layer specified. If the network is a trained network, then the activations will be that of the trained network.
The "using any of the previous syntaxes" refers to the positional argument syntaxes in the documentation page. It means that you can use the name-value arguments with any of the previously defined syntaxes.
