How can I get the output vector for each instance

[DecayedL]

When I test a pre-trained model, how can I get the output vector(state) of the encoder? ie, when I finish training a translation task from English to French, then I feed an English sentence, it will generate the corresponding French sentence, however, I want to know what vector does the English sentence encoded to? How can I get it ? Can save the vector or output it? Thanks.
