hi All, When I try to run kaldi/egs/wsj/s5/local/pytorchnn/run_nnlm.sh file for rescore, first script (lmrescore_nbest_pytorchnn.sh) rescore with n-best is ok. But when I try to use lattic rescoring (lmrescore_lattice_pytorchnn.sh) it's stop and get core dump error: 20fa42712d26e378ba37 I don't have any idea why it's happen and how to fix. Pls help.Tks

lattice-path-cover.cc is not a frequently-used program. The assertion: KALDI_ASSERT(clat.NumStates() > 1); at its line 41 does not look right to me. Compact lattices can legitimately have just 1 state, even nonempty ones. You could try just removing the assertion and see if it still runs OK. If so you could make a PR.
