c3_w2_UNQ_C1 AssertionError: Wrong value. Expected 27, got 12.0

Hi @Lucky_Agrawal,

Look carefully at how the cost function J looks like:

The regularization term is outside of the summation over i and j which means that it should be added to the J function after you exit from both for-loops (just before you divide J by 2).

In your code, you added a regularization term inside the for-loop. Therefore you add it multiple times and you should add it only once.

Hi @F_E Put adding the regularization term outside both for loops before you divide J by 2. If you do it like that for each loop you add the full value of the regularization term. In other words, you are adding it multiple times and you have to add it only once at the end of the calculation of J.
