Typically this type of error means you have modified your notebook in some why that has confused the grader.

Usual causes:

  • adding new cells
  • deleting cells
  • moving cells within the notebook
  • editing portions of of a cell outside of the area marked for your code.
  • renaming your notebook.

Hi, and welcome to the forum! Before you change anything, you can first try to just resubmit. There were a few reports about the Coursera grader being glitchy and the effect is that error message. The solution is usually to just resubmit. If the error persists, then you can address Tom’s point’s above. Hope this helps!
