I was able to resolve this issue after attempting all the cells. I was stuck at the second last cell, so I tried submitting the notebook by not attempting it, thinking I would get a passing grade even if the last 2 cells are not run.

I read through the TFX documentation and after 6-7 attempts got the cell code working correctly. Then when I submitted the notebook, the automatic grader graded the submission.

Make sure you attempt all the cells before submitting. Good luck!

Comment this last line in the last cell:

# Display the results
display_artifacts(store, parent_artifacts, base_dir) # <-- comment this line

There is a bug in that method that tries to use the property id instead of artifact_id in the list of parent_artifacts. This creates an error which fails the whole submission grader. Someone at Coursera needs to go update the code in the util library and change the property name.

This will give you 110/120 points, but at least you will complete the assignment.
