Hi again,
I’ve found out that that is not a bug or a documentation issue.
It’s due to your special example:
your labels are [11, 24, 24]. Therefore especially the last two are the same. So why does the problem occur, when the lengths are equal? Well, for the input to represent the same label twice in a row, there must be a blank in between those two, as that’s how CTC works, what is impossible to achieve with equal input lengths and target lengths.
