Initial Lambda Stack install -- Scope of installation? What gets installed?

I’m a newbie, setting up my first dedicated Deep Learning machine, Dual boot Windows 10/Ubuntu 18.04 Server, dual Nvidia 1080Ti cards.

I want to install Lambda Stack, and completed the installation; but I have a fundamental question about the state my system should be in after completion.

Does installing Lambda Stack also install all the various applications–TensorFlow, Keras, PyTorch, Caffe, Caffe 2, Theano, CUDA, cuDNN, etc.?

When my LS install completes, per instructions here, none of these applications/frameworks appear to be installed.

As I said I’m a newbie and maybe I’m just ignorant when it comes to docker files etc…but I can’t tell what’s been installed and what hasn’t.

Is there an expected directory structure posted somewhere that will show what should have been installed where, assuming the installation completed successfully?

Or do I have it all wrong, and still need to install each of the applications/frameworks separately after installing LS?

Apologies for the basic questions, any constructive input appreciated.
