I finished the Practice Lab of Week 1. Everything looks OK but I received an error as below. My code passed the previous test correctly. I don’t know why. UNIT TESTS test_c3(my_dense_v) AssertionError Traceback (most recent call last) in 1 # UNIT TESTS ----> 2 test_…

Your code needs to do these three things. Compute the matrix product of A_in and W. Add b. Use the ‘g()’ function and assign the result to A_out. If you choose to, it can be done in one line of code.

I used sigmoid() function instead of g(). It worked for the first quick check but failed the Unit Test. I still don’t know why. I replaced the sigmoid() with g() and it passed the test. Thanks!

To check if you are using g( ) correctly, the unit test uses a different activation function.

I got the same error in the unit test when I did not use np broadcast in the code. def my_dense_v(A_in, W, b, g): """ Computes dense layer Args: A_in (ndarray (m,n)) : Data, m examples, n features each W (ndarray (n,j)) : Weight matrix, n features per unit, j units …

Sorry, I do not know exactly what you are asking about. I would really like to see a screen capture image of the error message. Note: Personally I don’t like using the @ operator, because it doesn’t clearly define what operation is being done. I prefer using np.matmul(). In your code, I’d use ano…

I was not aware of the Code of Conduct and did not know that I should not post my code on the forum. Can you share the link to the Code of Conduct or elaborate why we should not post our code on the forum?
