title: How to use fairseq interactive with multiple gpu?
body: <p>I am trying to generate new prediction for the model, but I found it is not that intuitive to use fairseq. I found <code>fairseq-interactive</code> could help to generate with a good settings of batch_size, however, it seems that it will use 1 GPU at a time, I wonder if it is possible to use multiple GPU? Hope someone can kindly help!</p>
  <p>Many thanks :)</p>
