Hi there,

could anyone help?

Thanks in advance,

you can change the version of tensorflow, i tried it and it worked!

like @LanGuipeng mentioned, changing the version of tensorflow.
running import tensorflow on colab, will import the default version.
you can specify the version you want before you run the import tensorflow cell by adding
%tensorflow_version 1.x

hello, i'm having the same issue in my computer.

I'm trying to run MTCNN_video_face_detection_alignment.ipynb in my computer (it works in google collab) to get faces meanwhile i'm training a net in google colab, but I keep getting the message "module 'keras.backend' has no attribute 'get_session'".

I'm ussing the specified versions (python 3.6.4, tensorflow 1.6.0 and keras 2.1.5) and even I've tried different versions of tensorflow 1.x, but nothing works.

Edit: ok it seems that changing

from keras import backend as K

to

import keras.backend.tensorflow_backend as K

works.
