W3 - Final Graded Lab Assignment

W3 Final Lab - Code is correct but grade is 0/96

Hi, I am trying to complete the Machine Learning Specialization course but I am stuck in the last graded lab assignment. All of my code is correct and all the tests passed but I keep receiving a 0/96. I tried running all cells together but I am still receiving the same grade.

Could somebody please advice what my next steps should be?

Please find screenshots of the graded comments below:

Did you rename (or make a copy of) your notebook ipynb file?

No, I didn’t. I tried refreshing the tab and doing it again as well but it gave the same result.

The error message indicates that it is grading a notebook that you have not added any code to.

Did you add any cells to the notebook?
Did you delete any cells from the notebook?
Did you make any changes in the notebook except where it is marked for you to add your code?

I did not add/delete or make any changes in any part of the notebook other than where I should have. Is there a way you can access my notebook to see where the error could be coming from?

Please check your personal messages for instructions.
