If you ever wanted to do this:
r11, r31, r51 = vgg_net.forward(targets=['relu1_1', 'relu3_1', 'relu5_1'])
then this module is for you! 
This is something I made to scratch my own itch. I wanted to extract multiple features from (mostly VGG) models in a single forward pass, by addressing the layers in a nice (human readable and human memorable) way, without making a subclass for every combination of features I want to run.
After being unhappy with the solution I found here I sat down and made a module that is pretty much a replacement for torchvision.models.vgg. And now I finally published it as a PyPI module, instead of copying the files from one project to the next 
You can find it on github:
or simply install it via pip:
pip install pytorch-vgg-named
I also added the normalized VGG weights provided by Leon Gatys. If you use these, pay attention to the note on normalization in the readme file.
