I have an error in the excercise 9.The error seems to say that dZ’s dimension is 1,but I think the dimension of dZ is not 1,So I have no idea to solve this problem. How I solve this problem?

Hi @nananana,

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.

When you reply back, kindly tag me in the post so that I’m notified.
