Machine Learning Data Lifecycle in Production - Week 1: Grading of assignment failed/ new submission not possible

Hi Jorn!

Are you still facing this issue? Sometimes this is just a sporadic bug and the Submit button reappears when you open the notebook again after a few hours. If it is still missing, please try refreshing your notebook. Steps outlined in this post: C2W1 Assignment - grader output showed error - #4 by chris.favila .

Here are additional things you may need to watch out for to avoid that error:

  1. There should not be any cell in the notebook that throws an error. Otherwise, the grader will halt and not give a partial grade. This usually stems from submitting an assignment without completing all the exercises (e.g. doing Exercise 1 then pressing Submit immediately)
  2. You may have renamed the notebook and pressed the Submit button there. The grader expects the default filename when grading. That is the file opened when you launch the notebook from the Coursera classroom. For example, if the default filename is C2W1_Assignment.ipynb , then the grader will grade that notebook even if you pressed the Submit button from C2W1_Assignment_2021_05_11.ipynb

Hope this helps!
