Unexpected Grading Error in NLP Specialization – Course 1 Week 4 Assignment

Course Q&A Natural Language Processing NLP with Classification and Vector Spaces
,

I am experiencing Unexpected Error: “Grader Feedback not Found” while submitting my Course 1 week 4 assignment of Natural Language Specialization course. However, I have update the version, Reboot the lab and also contact the help center but they have replied me this:
"I see this is related to the assessment “Word Translation” in the “Natural Language Processing with Classification and Vector Spaces” course.

Upon review, I found the following feedback about your programming, which explains the grade you’re getting:

{“errorCode”:null,“message”:“SubmissionId dgtvlUtrEfChVwr_7CqwTQ doesn’t belong to course branch _ZpZKyTxEemb-BL8g3X_rg”,“details”:null}

I regret to inform you that because solving that code is a course-content question, I’m afraid we are unable to assist you. My apologies.

Therefore, my best advice is that you join and post in deep learning Forum and specifically ask for help on how to solve that programming error code, so that you can be assisted by the Course Staff themselves. "
Any one can Guide how to resolve this ?

I’ve never seen the message that the Help Center quotes about the error related to the “SubmissionId”, but it sounds like some kind of problem related to the session of the course that you are subscribed to. This is the 4th assignment in that course. I assume you’ve not seen any problem up to this point. Please advise if that’s not correct.

My first suggestion would be to try the old “Log out of Coursera and then log back in again” trick and see if that helps. Try submitting to the grader again after logging back in.

If that doesn’t help, the next thing to try would be getting a clean copy of the notebook (see instructions here) and then carefully “copy/paste” over just your solutions from the “YOUR CODE HERE” sections and then try submitting again.

Please let us know whether either of the above help (or not :weary_cat:).

To close the loop on the public thread, the reason that the grader fails and gives 0 points for everything is that the definition of some of the graded functions was changed. In all the cases where functions take other functions as arguments, those “named parameters” were removed.

For example, instead of:

# UNQ_C8 (UNIQUE CELL IDENTIFIER, DO NOT EDIT)
def nearest_neighbor(v, candidates, k=1, cosine_similarity=cosine_similarity):

The notebook changed the definition to be:

def nearest_neighbor(v, candidates, k=1):

It is not recommended to change things that are just given to you, but in particular changing the definitions of graded functions is always a bad idea. :nerd_face:

Please try fixing those issues and see how far that takes you.
