Issue in grading (says loss_function not found)

My 3rd graded function UNQ_C3 has passed all the test cases successfully, but after submission, auto grader gave me 0/100 . This is the error grader is showing me the submission section:
“Cell #UNQ_C3. Can’t compile the student’s code. Error: VariableNotFoundError(‘Variable loss_function not found in Code Cell UNQ_C3. Please make sure you have not altered the cell positions from the original exercise question.’)”.

I have not altered anything in my code accept where I was supposed to.


Please help me if you know how can I correct it.

Issue solved! I just re-submitted the assignment after a couple of days, and this time it worked fine.
