Hello my Mentors, I thank you all for working on us to complete our assignment.
I was able to get the cost with and without regularization.
But my cofi_cost_fun test 1 failed. Below is the error massage.
Please assist.

Hello @Onuorah_Martins_Onye

Check the indentation of regularization term and check the following post also…
