[insigh]

hello, have you solved the problem? I have the same one with you, looking forward to your solution.

[ljcyu]

I also meet the same problem, it is useful to try other lower version Keras .

[xaviOwO]

Hello the problem is given by the tensorflow version and I downloaded the V: 1.12 and it was solved.

If you have problems besides that in rec-face.py and add:
def triplet_loss (y_true, y_pred):
     from keras import backend as K
     return K.max (K.abs (y_pred - y_true), axis = -1)

And add to load_model this:

FRmodel = load_model ('face-rec_Google.h5', custom_objects = {'triplet_loss': triplet_loss})

Greetings, sorry for the translation use google translator, I speak Spanish.

Fixed in last Keras
keras-team/keras#10648

[gdut3118007086]

pip install keras==2.1.6
or
use anaconda to get keras==2.1.6
thanks

[hayatkhan8660-maker]

i solve the same problem by downgrading the keras version from 2.2.4 to 2.1.6
