How to change code when each sequence length is different

[REDXXXX]

Dear sir:
Sorry for my rude words.But I do really want to know how to change the code if the sequence length is different.It seems that ntm need sequence length to be the same.
I tried to fill short sequence with zero but the ntm use attention and if filled with zero the predict rate down.
I want to know how could I do to overcome the problem.Please help me.
Best wishes to you.

The sequence length doesn't have to be the same, you can end each sequence with a special delimiter. The input sequence length is also randomized between 10 to 20 in the copy task and you can even see an example of variable length output in the repeat-copy task where the NTM learns to output a sequence multiple times and end it with a delimiter.
