Even though my codes in the practice lab of week 3 of Machine Learning are perfectly fine as I have completed them following the hints, the grader output is showing error in almost all the cells and I’m not being able to pass the assignment. Can anyone please help me in this regard?

Hmm, can you try and reset the lab maybe you have a problematic version or you might have changed something that you are not supposed to. Make sure to save your current work if you do that!

Please post a screen capture image that shows the grader’s detailed feedback.

You will need to click on the > marker next to each grade to see the details.

Thanks a lot for your response but I have passed after trying a number of times.

Thanks for your report.

Usually just resubmitting your notebook does not fix errors in grading - unless you had made changes to your notebook and did not save them before grading. The auto-save in the notebook takes some time before it activates.

It’s a good idea to use “File → Save and checkpoint” before you submit the notebook for grading.

Ok. Thank you.
