   This is annoying for us because we need to use topk in our CRF Viterbi decoding during inference (for k-best Viterbi).
   
   Because topk doesn't support float16 this means we have to convert from float16 to float32 before doing k-best Viterbi decoding. Since this is the most time consuming part of inference, we would prefer to be able to benefit from float16 operations here.
