i try submitting my programming lab assignment of gradient descent cost prediction but it keeps saying “grader feedback not found”
how do i resolve this issue?

This suggests that you have modified your notebook by deleting important data, like the comment lines which contain the grader keys.

You may need to delete your notebook ipynb file, and get a fresh copy to start over.

Be extremely careful that you do not make any unnecessary changes to the notebook.
Don’t delete anything unless you’re specifically told to.
Don’t move cells.
Don’t add cells.

You have probably deleted some cells of the notebook thats why.

In the right hand corner at the question mark, you can refresh the assignment to its original version with “Get Latest Version” option, but delete the current file before you do that!
