fstdeterminizestar nnet3 model(not chain) #1509

Hi, dear author

when I ran ./local/lookahead/run_lookahead_no_ivector.sh in a nnet3 model to get vosk-like model, it cost all memory(more than 450GB) in server, and killed, it stuck in fstdeterminizestar. And I change nnet3 model to chain model, it become normal. Any idea to fstdeterminizestar nnet3 model or make nnet3 model lookahead?

Yeah, overall determinization is like magic. It can fail sometimes. Some FST experts might help, but unlikely I can suggest you something quick right now, sorry.
