All tests passed but grader failed

EXERCISE7
Cell #24. Can’t compile the student’s code. Error: TypeError(‘cannot unpack non-iterable NoneType object’)
but there are only 5 exercises in this assignment
help please !

Hi maha99,

This error sometimes occurs when you add a cell to the notebook, that cannot be compiled by the grader.

It can also happen if you try to submit a notebook without completing all of the tasks.

The “NoneType object” error can happen if there are “None” statements in the notebook that you haven’t replaced with your own code.

Also, “Exercise 7” comes from how Coursera numbers the parts of the assignment - they are not the same as the numbers that are used in the notebook instructions.

I have the same problem. All tests are passed. My entire DL course is finished except this one assignment. How do I solve this problem? I didn’t add any new cells to my notebook. Can send my notebook someone to check? Or can someone reset my notebook?

I still have the issue. Cell #24. Can’t compile the student’s code. Error: TypeError(‘cannot unpack non-iterable NoneType object’).
Tried it multiple times with all the suggestions, no luck yet.
