A FAIRSEQ. This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. When building a sequence using special tokens, this is not the token that is used for the end of sequence. Allenlp is opinionated but fairly extensive about how to design an experiment and develop model code, where as torchtext and pytorch-nlp have more out of the box utilities. .
