I'm working with Google Colab and neuronet. As a backend, I need to use theano, but as far as I know, Colab defaults Tensorflow. I tried to
import os
os.environ["KERAS_BACKEND"] = "theano"
import keras.backend
keras.backend.set_image_dim_ordering('th')
but get the following error:
AttributeError: module 'keras.backend' has no attribute 'set_image_dim_ordering'.
Downgrading keras doesn't make any effect. How can I solve that?
