I developed this to learn how Tensor Flow worked. Its no longer being maintained. However you should be able to use the vgg_face model in tensorflow.
Download network.h5 and place it in vggface directory from https://www.dropbox.com/s/7g4nhq4a467jzgv/network.h5?dl=0
Please note that use of VGG Face recognition models must adhere to requirements specified here: http://www.robots.ox.ac.uk/~vgg/software/vgg_face/
