W2A2 - Grader Error - 0/100 - even though "All Tests Passed!"


I was getting the attached grader error after completing the function “data_augmenter()” even though the test code block output indicated “All tests passed!”

I worked through the posted instructions on resolving grader errors (esp the one about deleting, and downloading the notebook) but same error appeared.

Finally, I tried submitting an unmodified file: I deleted my work, downloaded and submitted a fresh copy of the file without modifying it and the same error appears.

Any ideas?

You have to complete all parts of the assignment before you can submit it for grading. Any “None” statements in the code that you’re supposed to replace will cause a runtime error.


@TMosh Much appreciated!
