Feature extract using VGG

[midmelody]

Inception and Resnet are both fine, but when I tried to use vgg_16/19, I came up with some strange error "Invalid argument: Assign requires shapes of both tensors to match", and print_network_summary() did not work. Could you give an example for VGG? Thanks!

--layer_names=vgg_16/fc8

print_network_summary() works.
