Hey @lgoyal50_be19, please replace the below line from the backword function in your code

delta_1 = (1-np.square(a21))*np.dot(delta_2,W2.T)

by the following code

delta_1 = (1-np.square(a1))*np.dot(delta_2,W2.T)

Then run your notebook from the starting. It should work as expected !
I hope this helps ! :+1:
Happy Learning ! :smile:
