Access value of the weights of these models

I have this notebook:

It contains 3 networks: vgg_a, vgg_b and vgg_star. In particular I have vgg_star and vgg_star after a sum of weights of vgg_a and vgg_b.
I want to see the numerical values (to see if there are patterns for example) of vgg_star and vgg_star after the sum of weights.
What I have to change in order to do this?
