Prediction is giving error of input shape in cell 28.

Dimensions must be equal, but are 40 and 50 for 'simplecontext_1/add' (op: 'Add') with input shapes: [64,40,40], [64,1,50].

This error occurs in lines 10 of the function simple_context() in cell 27.
Fix the code in lines 8 from
activation_energies = K.batch_dot(head_activations, desc_activations, axes=([2],[2]))
to
activation_energies = K.batch_dot(head_activations, desc_activations, axes=(2,2))

After you fix this error, you should also fix the code in lines 18 from
desc_avg_word = K.batch_dot(activation_weights, desc_words, axes=([2],[1]))
to
desc_avg_word = K.batch_dot(activation_weights, desc_words, axes=(2,1))
