Setting Google Colab to use Theano as Backend

Question

I'm following an online tutorial which uses Theano as backend. I am using Google Colab which defaults to Tensorflow as backend.

How can we switch to using Theano as backend? Thanks

Answer 1

This will help,

import os
os.environ["KERAS_BACKEND"] = "theano"
import keras.backend
keras.backend.set_image_dim_ordering('th')
