Unexpected error in grading

Hi, Angel.

I am not a mentor for NLP and have not even taken that course, so I can’t help with the actual details of the assignment, but that generic “Grader feedback not found” error from the grader sounds like a structural problem with your notebook. Are you sure you didn’t work on the notebook on Colab or some other platform and then re-upload it back to the course website? If that’s not the problem, then here are a couple of things to try:

The first thing to try is to remove all the generated output from the notebook and submitting again:

  1. Kernel → Restart and Clear Output
  2. Save
  3. Submit

The point is that the grader does not need the generated output in the notebook and it’s possible that it might create some syntax that interferes with the grader.

If it still fails after that, then you can also try getting a clean copy of the notebook (See this thread) and then very carefully “copy/paste” over just your completed code from the “YOUR CODE HERE” sections and then submit again without even running the notebook.

If neither of those things help, please let us know and then we need real help from one of the NLP Mentors.
