W3_A1_Tests passed; graded 0

Hi, my week 3 assignment notebook passes all tests but it has been graded 0. PFA the image below. What can be the reason?

Can you please share the screenshot (or code) of the second last cell? Under the 6 - Tuning hidden layer size (optional/ungraded exercise).

On reading your reply, I got to know that only [1, 2, 3, 4, 5] are allowed as hidden layers when submitting. I submitted again and passed the assignment. Thanks man!

I am glad you submit it. What were the original values of these hidden layers?
