Course Submission Issue: Grader Feedback Not Found Error

Hello everyone,

I’m currently enrolled in Natural Language Processing in TensorFlow and encountered an issue while submitting my assignment. After submitting it, I received the following error message:
“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.”

Has anyone else experienced this issue? If so, how did you resolve it?

Must be a broad issue. Getting the same error in the Neural Networks and Deep Learning course.

Yes, I tried one of my notebooks for DLS, and also got “Grading failed”.

@Mubsi for awareness.

I got the same error when submitting the assignment as well.

That’s good to know.

Me too, yet I’ve tried many times

It has not been fixed yet.

I encountered the same error in the Convolutional Neural Networks course from the Deep Learning Specialisation.
I realised that the problem was the fact that all your code has to go between the #Your code starts/ends here comments.
However, the way how the notebook is written strongly suggests you put it right after the suggestions, for example before the block where you should put your code you will find stuff like:

# do X
# Z = a, b, c

And then one is tempted to put the code there. Instead, you have to copy paste this to the “put your code here” block and then uncomment and fill in with the right solution.

Really poor usability - I remember doing the course a while ago and I did not remember the notebooks being so unintuitive.

Coursera fixed the issue try submitting again its fixed I think

That’s not strictly true. Unless your code causes a runtime error or causes defects, it doesn’t really matter how you write the code. The grader never looks inside your code at all. It only tests the return values.

So as long as your code is functionally correct, you can do as you like.

You are more likely to have errors if you don’t put the code in the marked locations inside the function, but it’s not a strict rule.
