It represents the length of each target sequence in "inputs" parameter.
Check : http://higepon.hatenablog.com/entry/20171212/1513076578 for example.
It is used for checking if the target sequence tokens exhausted, when feeding each token to decoder. Check the following: https://github.com/tensorflow/tensorflow/blob/r1.10/tensorflow/contrib/seq2seq/python/ops/helper.py#L244

Guys it's like sequence length, like something you provide in dynamic rnn, so you know that's the end of the sequence. – shivam13juna Dec 26 '18 at 10:38
