AttributeError: module 'tensorflow' has no attribute 'matrix_band_part'

[mahmuduzzaman]

In this section of code :

# bilinear term
print("Question context shape ",q_cont.shape)
print("final o/p of context ",c_.shape)

logits = BilinearSimilarity(UNITS)(q_cont,c_)
Y_prob = Prediction()(logits)
print("Logits shape ",logits.shape)

I am getting an error
