Week 3 assignment: bug in the test

Course Q&A Deep Learning Specialization Neural Networks and Deep Learning

Hi @paulinpaloalto , @Rashmi

Now I have changed the code

 W1 = np.random.rand(n_h, n_x)*0.01
    b1 = (np.zeros((n_h,1)))
where n_h = n[1] and n_x = n[0]

So, the initialization has the following values for W1 when called for the test method

[[0.00435995 0.00025926 0.00549662]
 [0.00435322 0.00420368 0.00330335]
 [0.00204649 0.00619271 0.00299655]
 [0.00266827 0.00621134 0.00529142]
 [0.0013458  0.00513578 0.0018444 ]]

with
n_x → 3
n_h – > 5
n_y —> 2
But the expected value is

W1 = [[-0.00416758 -0.00056267]
 [-0.02136196  0.01640271]
 [-0.01793436 -0.00841747]
 [ 0.00502881 -0.01245288]]

which is 2X4 array
I am getting the below error now

~/work/release/W3A1/public_tests.py in initialize_parameters_test(target)
     57     assert parameters["b2"].shape == expected_output["b2"].shape, f"Wrong shape for b2."
     58 
---> 59     assert np.allclose(parameters["W1"], expected_output["W1"]), "Wrong values for W1"
     60     assert np.allclose(parameters["b1"], expected_output["b1"]), "Wrong values for b1"
     61     assert np.allclose(parameters["W2"], expected_output["W2"]), "Wrong values for W2"

AssertionError: Wrong values for W1

The expected value in the test cases are

expected_output = {'W1': np.array(
        [[-0.00416758, -0.00056267, -0.02136196],
         [ 0.01640271, -0.01793436, -0.00841747],
         [ 0.00502881, -0.01245288, -0.01057952],
         [-0.00909008,  0.00551454,  0.02292208],
         [ 0.00041539, -0.01117925,  0.00539058]]), 
                       'b1': np.array([[0.], [0.], [0.], [0.], [0.]]), 
                       'W2': np.array([[-5.96159700e-03, -1.91304965e-04,  1.17500122e-02,
        -7.47870949e-03,  9.02525097e-05],
       [-8.78107893e-03, -1.56434170e-03,  2.56570452e-03,
        -9.88779049e-03, -3.38821966e-03]]), 
                       'b2': np.array([[0.], [0.]])}

But the value created by the method, does not match. Value created by the method
are

W1 = [[0.00435995 0.00025926 0.00549662]
 [0.00435322 0.00420368 0.00330335]
 [0.00204649 0.00619271 0.00299655]
 [0.00266827 0.00621134 0.00529142]
 [0.0013458  0.00513578 0.0018444 ]]
b1 = [[0.]
 [0.]
 [0.]
 [0.]
 [0.]]
W2 = [[0.00785335 0.00853975 0.00494237 0.00846561 0.00079645]
 [0.00505246 0.00065287 0.00428122 0.00096531 0.0012716 ]]
b2 = [[0.]
 [0.]]

Can you please check if I am doing something wrong?
