Course 1 - week 2 assignment AssertionError: Wrong length for d['costs']. 20 != 1

That error usually means that you are “hard-coding” the number of iterations and perhaps other parameters someplace. You’ve done 2000 iterations which is why you get 20 cost values, but the test case is asking for a smaller number of iterations. So how could that happen? Typically this happens when you call optimize from model: there should be no equal signs in any of the parameters being passed to that function, because that means you are ignoring the parameters being passed in at the top level…
