toy task-example1-error

[bharathichezhiyan]

I have no problem executing Test forward pass.
but the output for Test forward pass are
batch_encoded:
[[6 3 9]
[0 4 8]
[0 0 7]]
decoder inputs:
[[1 1 1]
[0 0 0]
[0 0 0]
[0 0 0]]
decoder predictions:
[[9 3 3]
[8 3 0]
[0 3 0]
[0 3 0]]

I belived the decoder predictions need not to be same as yours. so I move forward to Training on Toy task. I am getting error.
