C3W2Q3.4 label_vectorizer error

I’m receiving this error message despite passing the padding=‘post’ argument

Wrong output. Please review your code. Remember to pass the argument padding = ‘post’.
Expected: [[ 1 1 1 1 1 1 1 1 1]

Please advise

Josh can I know where you used padding = post?

Was it for the last code line?? Or inside the label vectorizer function call?
