I’m enrolled in the NLP specialization (https://www.coursera.org/learn/sequence-models-in nlp/home/week/1), and I’ve been doing all assigments to get the certificate of completion. In week 1, I can’t get grades. It fails with:
Grader Error: Grader feedback not found
Visit the Discussion forum to see if your peers are experiencing or have found resolutions for similar errors. If the error isn’t resolved in 24 hours, please reach out to Coursera through our Help Center.
Although all the unit tests have passed on running the notebook.
This thread isn’t for questions about the assignments.
I’ll move it into the Week 1 discussion area for NLP.
The first thing to check is that you followed all of the tips that are listed at the top of the notebook.
That error typically means that there is something corrupted or damaged about your notebook at the “metadata” level. Meaning that it’s not that your code is wrong, but that something has damaged the other structural parts of the notebook. Did you edit the notebook on any other platform besides the course website?
My suggestion as the next step would be to get a fresh copy of the notebook by following this procedure. As part of that process, you have to rename your existing notebook. Once you have the clean copy, then very carefully “copy/paste” over just your completed code segments from the “YOUR CODE HERE” sections of the original notebook and try the grader again.
