Grader error for submission for the Part 2 task

I finished both tasks, everything works and passes, but on the submission I receive
" * ### Grader Error: Grader feedback not found

Any ideas?

Did you do any of these things?

  • Add a new cell to the notebook?
  • Delete a cell from the notebook?
  • Move a cell within a notebook?
  • Copy-and-paste a cell from a different notebook?
  • Download the notebook and work on it using some other platform?
  • Did you change the notebook’s file name?

The issue was different - apparently I did not supply the correct requirements.txt.
This is solved, but now I have another issue. No matter what I do with the code, I receive
“There was an error grading your submission. Details:
‘income_day’”.
I tried all sorts of things and spent good 16 hours on it.
Moreover, I incidentally deleted schedule.json and cannot recover it.
Is there a way to fully restart the lab and reset it to an original state?
I am fully stuck now!

  • Open the File Browser tool (top of the left side menu)
  • Delete all of the .py files.
  • The use the “Lab Help” menu (the question mark inside a circle), and use “Get latest version”.

This will give you new copies of all the missing files.

Note that “Get latest version” only restores files that are missing - it will not update a file that already exists.

Thank you - it solved my problem!
