Hi @ParikhKadam

I have been trying to recreate your Keras-bidaf model in my python notebook and running this code in python from bidaf.models import BidirectionalAttentionFlow which keeps giving me the above error and saying Adadelta can't be imported from Keras. I have tried so many options to solve it but no luck.

I have tried the below solution as well. But it keeps throwing me the same error. I

import tensorflow as tf from tensorflow import keras from tensorflow.keras.optimizers import Adadelta

I am totally clueless about how to solve this issue. Any suggestions and solutions are highly appreciated.
