The function call of propagate() in jupyter exercise notebook uses [[1, 1, 0]] for the value of Y, where as the propagate_test() in public_tests.py uses [[1, 0, 1]] for the same. I think because of this I’m getting the following error, AssertionError: Wrong values for grads['dw']. [[-0.00154399] …

In my notebook version this propagate_test is already fixed to use the same value, but seems that it checks our outputs against wrong values, derived with input [1,0,1]. So, there is still a bug in this function, but in a different place now

Yes, It’s checking against [1, 0, 1] but calculating against [1, 1, 0] in the notebook.

Hi, I don’t see that in the public_tests.py, I don’t know if these files have been recently updated but I see the right same values in both the notebook and the corresponding tests. def propagate_test(target): w, b, X, Y = np.array([[1.], [2.]]), 2., np.array([[1., 2., -1.], [3., 4., -3.2]]), n…

Hi, it seems there was a bug there check the following thread. [image] Week 2: Programming Assignment Neural Networks and Deep Learning Dear Team, I am getting a ValueError : shapes (1,4) and (2,3) not aligned: 4 (dim 1) != 2 (dim 0). I have tried to change optimize fun…

OK, they must have fixed the error. Nevertheless, I finished the assignment. Thank you.

Thank you for replying me back. I have tried to complete my DLS week 2 course 1 assignment today, but now also the error has not been fixed in my notebook. It is showing similar error. All the previous tasks are pass but model function is not running till now also… please help me out… the deadline …

Test cases are compatible with the updated notebook. Make sure you are using the updated notebook, I was making a similar mistake.

Possible mistake in public_tests.py for propagate() testing
