Grader Error: Grader feedback not found - Week 4 (NLP with Classification and Vector spaces)

Hi Team,

I am facing issues in submitting my assignment for Week 4 of NLP with Classification and Vector spaces course.
All the test cases are passing, and I haven’t deleted any cell or edited any cell which can cause this. I have tried all the things mentioned in similar posts, but had no luck so far.

My lab id is : hlmintcoxnir

Could anyone please help? It’s urgent.
Thanks

thank you @atuldwivedi007 for following community guidelines.

please post screenshot of your submission grader feedback without posting any codes that grade your assignment as posting grade function codes is considered violation of Code of conduct.

Yes, thank you for following the guidelines and not posting your code. Also please note that the mentors can’t directly view your notebook.

That type of error from the grader usually means something structural is wrong with your notebook. Did you add any cells or work on the notebook on some other platform and then re-upload it to Coursera? If so, that is very likely to cause issues like this. In that case one thing to try is to get a clean copy of the notebook and carefully “copy/paste” over your code only in the “YOUR CODE HERE” sections. Here are the instructions for how to get a clean copy.

The other easier experiment to try is to submit again, but with the generated output from running your notebook removed. Please try this sequence:

Kernel -> Restart and Clear Output
Save
Submit

The point is that the grader doesn’t need to see your output: it just needs to call your functions and check the return values. Clearing the output minimizes the size to be uploaded to the grader and reduces that chances that any of the generated output interferes with the grader.

You can try that first, before doing the “clean copy” procedure which is a lot more work.

Let us know what results you get from trying those things. If none of that helps, there are ways we can look at your code that are not public.
