Hello @ppm28 and @Sdumo_LuckySibiya!

Please be sure that you do not add any function in the solution code blocks apart from the solution itself and the functions that are already in the block. It may break the autograder.

If this is not the case, let me know.
Thanks,
Lucas

Hi @Sdumo_LuckySibiya,

Can you share your lab ID with me ? In the assignment, when you click the top right “Help” button, a panel will open and your lab ID will be shown at the bottom.

I shall take a look.

Thanks,
Lucas

Hi Lucas -
I’m having the same problem. There’s nothing in the cell but calls to np.linalg.det and np.linalg.solve. I’ll message you my lab id.
