Hi, I am studying machine learning specialization courses. For supervised machine learning week2 and week3 practice lab. I follow the hints and pass all tests, but still don’t get full score. Could you please help to check this problem?
This is a rather common situation.
Passing the tests in the notebook does not prove your code is perfect.
The grader uses entirely different tests, and a different runtime environment.
The first things to check are (not a complete list)
- Do not rename your notebook. The grader always uses the original file name, regardless of the name of the notebook you have open.
- Do not write code that uses global variables. The grader will not provide those when it tests your code.
- Manually save your notebook changes before you run the grader. The auto-save feature is not very reliable.
- Check the detailed feedback from the grader. Please post some screen capture images showing the details.
Thanks a lot. It has been solved
