How to use seq2seq for simple sequences 

Hi 

I have a simple categorical sequence data set like 
Target has 3 classes

X1 | X2 | X3 | X4 | X5 | X6 | X7 | X8 | X9 | X10 | X11 | X12 | Target
-- | -- | -- | -- | -- | -- | -- | -- | -- | -- | -- | -- | --
0 | 1 | 1 | 2 | 2 | 2 | 3 | 3 | 3 | 3 | 3 | 3 | 1

Will be able to use seq2seq for these king of problems?
can you sample syntax

Thank you.
