Dear all,
Greetings!
I wanted to share my experience with the assignment auto-grader in “Module 4 Assignment: Deeper Analysis of the Movie Data with SQL” in case it helps others who may encounter similar issues to mine.
I encountered persistent auto-grader errors despite making multiple corrections to my code. The auto-grader continued to flag the same errors even after I believed I had resolved them.
@chris.favila assisted me in identifying an initial error in my code. However, even after implementing his suggested correction, the auto-grader continued to display the same error messages. Upon downloading and examining my notebook file, I discovered that my corrections had not been properly saved or updated in the system. So, I resolved this issue and the error messages by replacing the notebook and rewriting the code. Fortunately, I had downloaded the original unsolved notebook before starting my assignment.
While the initial coding errors have been resolved, I experienced a different auto-grader issue on the way, with the following message: “Grader Error: Grader feedback not found. Visit the Discussion forum to see if your peers are experiencing or have found resolutions for similar errors. If the error isn’t resolved in 24 hours, please reach out to Coursera through our Help Center.”, which later resolved after refreshing and resubmitting the notebook couple of times.
The take away:-
Verify that the code changes are being properly saved and updated.
Consider downloading notebooks to check if corrections are properly saved on the system.
If necessary, replace notebook files and rewrite the code.
Kind regards,
