Hi guys, I keep encountering this error, and I have spent so long trying to solve it. If anyone has any ideas, please let me know. This is for the Week 4 Deep Neural Network Assignment.

Cost after first iteration: 0.6931477726958
Error: Wrong output for variable W1.
Error: Wrong output for variable b1.
Error: Wrong output for variable W2.
Error: Wrong output for variable b2.

Are you sure that you did not manually import your version of the initialization function from the previous Step by Step exercise? They gave you the functions from the previous assignment as imports here and they had to use a more sophisticated initialization algorithm that won’t be covered until DLS Course 2 in order to get reasonable convergence on this model.

omg yes, i totally misunderstood the question. i may have been too tired. and i totally forgot that the assignment only requires us to fill up the sections where it explicitly mentions to fill up, thank you so much!
