I’m not very sure that what is the parameter “tgt” means.
The document says it is the sequence of decoder. However, I have a question that since I have the sequence to decoder, thus I have the result of decoder, why do I have to use transformer for inferencing?In  another word, in inferencing process, we have no corresponded tgt to input.
For example, I have a seq2seq task that translate “I love you” from English to Franch “Je t’aime”, what is the parameter of “tgt”?
Looking forward answering. Thanks!
