6.2.5 Python implementation using FaceNet

[zoldaten]

Code in section gives a error:
face_model = InceptionResNetV1()
NameError: name 'InceptionResNetV1' is not defined
I`ve looked up at inception_resnet_v1.py followed link:
https://github.com/davidsandberg/facenet/blob/master/src/models/inception_resnet_v1.py

and couldn't find any InceptionResNetV1 function to initialize...
