Hello @namhainguyen2803, welcome to the community!

Please make sure you’re using the latest version of the assignment notebook, as old versions don’t include important metadata for grading which causes the error despite the code being right.

If this does not solve the problem, proceed with mr.@Hirwa for further assistance.

Hello @aryaprashant047 ,

Welcome to the Community!

Just few days ago I came across a similar case in a different week here : https://community.deeplearning.ai/t/c2w1-assignment-failed-test-case-has-incorrect-type/145649?u=nilosreesengupta.
The issue was not passing the test cases.

One has to be very specific with the code.

I would like to suggest you to go through the hints and the paragraphs thoroughly to pass the test cases.Specific criteria is written there.

If still you keep getting errors, post in Community, I or other mentors will surely help you.

With regards,
Nilosree Sengupta
