Course 4 Week 3: Car detection - yolo-eval

For the assignment, I am getting:
Code Cell UNQ_C1: Function ‘yolo_filter_boxes’ is correct.
Code Cell UNQ_C2: Function ‘iou’ is correct.
Code Cell UNQ_C3: Function ‘yolo_non_max_suppression’ is correct.
*Code Cell UNQ_C4: Unexpected error (InvalidArgumentError()) occurred during function check. We expected function yolo_eval to return yolo_eval test 1 failed. Please check that this function is defined properly. *
If you see many functions being marked as incorrect, try to trace back your steps & identify if there is an incorrect function that is being used in other steps.
This dependency may be the cause of the errors.

Is there a way to rectify this?

I was able to fix it with the following steps:

  1. P​ress Kernel → Restart & Clear Output
  2. P​ress File → Save and Checkpoint
  3. Submit

One thing to be aware of is that hitting Submit does not automatically do a save, so what the grader sees may not be what you see.

I actually had the same issue. I suggest you add a warning, “Clear Output Before Submitting”, just like you did for the second assignment.
