My error is shown below. My propagate function tests no problem, I don’t know why there is an error after optimization calls propagate. AssertionError Traceback (most recent call last) in 7 print("Costs = " + str(costs)) 8 ----> 9 optimize_test(optimize) ~/work/rel…

Finally solved the problem, thanks to Elemento‘s help. There is a typo in your optimize function. You have written b = b = learning_rate * db whereas it should be b = b - learning_rate * db . I hope this helps.
