Hi I can not find my error ,I passed the test in the propagate function but in optmize I get this error.
Why I get the wrong cost if my code passed the test in the propagate function?
Notice that your first cost value (at 0 iterations) is correct, but the second one increases instead of decreasing. This suggests that there is something wrong with your “update parameters” logic, which is part of optimize. E.g. are you sure you are subtracting instead of adding the gradient times the learning rate? In other words, this is not a problem with propagate: the problem is that you are passing propagate incorrect values because of a bug in your optimize logic.
