Module 1: Assignment: Analyzing retail sales with Python

Hi everybody! When I submitted this lab it graded all my excercises except excercise 1. This is the error message I’m getting: Grader Error: Grader feedback not found.

Please assist me.

(I’m not a mentor for this course, just a couple of general tips):

Is there any more detailed grader feedback (maybe a popup button you can click)?

“Grader feedback not found” often means that you’ve made some improper changes to the notebook, like adding, deleting, or moving cells, or deleting code that the grader needed.

Hi @clivemach, welcome to the forum!

As @TMosh already mentioned, issues with the grader usually mean the object being graded has some issue. The good news is that resetting your notebook usually solves this issue.

You can follow the instructions here on how to do that: Data Analytics: Assignment Troubleshooting Tips (Coursera Labs) .

Good luck!
