My output looks correct for the initialize_parameters function. However, the test is failing.
Please advise, thanks
Nick

W1 = [[0. 0. 0.]
[0. 0. 0.]]
b1 = [[0.]
[0.]]
W2 = [[0. 0.]]
b2 = [[0.]]
Error: Wrong output for variable W1.
Error: Wrong output for variable W2.

Hi, your output doesn’t look correct, it is all zeros and you are expected to initialize the weights as per the instructions:

Use this random initialization for the weight matrices: np.random.randn(shape)*0.01 with the correct shape
