Hi @Bakhtiar_Rasheed , to help debug the code, write a print inside your code for both dZ.shape and Z.shape to see what is going on.
Keep learning!

Hello @Bakhtiar_Rasheed! I hope you are doing well.

So, this is assignment 2 of week 4. You are making a typo in two_layer_model Ex. 1. What should be the input argument for dA0, dW1, db1 = linear_activation_backward()?
Double-check it.

Best,
Saif.
