Hi, I’ve got a bit of a problem with the grader output. Despite passing al the tests, I keep getting a score of 0/100, along with the following error message:
[ValidateApp | ERROR] nbgrader encountered a fatal error while trying to validate ‘submitted/courseraLearner/W3A1/Autonomous_driving_application_Car_detection.ipynb’
I noticed that I have somehow duplicated the cell of the test for the iou(), but I don’t know how to remove the cell. I’ve already tried refreshing my lab etc., but nothing seems to help.
All tips are welcome
