All my code works, till Exercise 8 (. The code looks correct, but I am getting an assertion error:
AssertionError Traceback (most recent call last)
in
1 from public_tests import *

----> 3 model_test(model)

~/work/release/W2A2/public_tests.py in model_test(target)
126
127 assert type(d[‘costs’]) == list, f"Wrong type for d[‘costs’]. {type(d[‘costs’])} != list"
→ 128 assert len(d[‘costs’]) == 1, f"Wrong length for d[‘costs’]. {len(d[‘costs’])} != 1"
129 assert np.allclose(d[‘costs’], expected_output[‘costs’]), f"Wrong values for d[‘costs’]. {d[‘costs’]} != {expected_output[‘costs’]}"
130

AssertionError: Wrong length for d[‘costs’]. 20 != 1

I am stuck here. Please help!

You probably hard coded the number of iterations. Test case only use 50 iterations, I guess.
