Hi @hoanghoson1209 , welcome to the DLS !

There is something missing in the one\_hot implementation. Please look carefully the exercise instructions and you’ll find the missing step.

Also please, assign the “DLS Course 2” category to the post, so it’s easier for Mentors to find questions, and also for fellow students that can have the same problem.

Thanks !!
