I try to re-estimate the spectrum models and duration models using HTS HERest after the decision tree-based clustering. I use the following command in the 1st and 2nd re-estimation.
/usr/local/HTS-2.1/bin/HERest -A -D -T 1 > logs/durCDERest_after_tree3.log -C lists/trn_dur.cfg -H lsp_for_duration_modeling/TRI/hmms/HMM1.2/hmmdefs -N dur/TRI/hmms/HMM1.2/hmmdefs -M lsp_for_duration_modeling/TRI/hmms/HMM1.3 -R dur/TRI/hmms/HMM1.3 -m 1 -u tmvwdmv -w 3 -t 1500 100 5000 -S scp/aligned.scp -I mlfs/train_tri_nosp.mlf lists/real_tri_nosp.list lists/real_tri_nosp.list
/usr/local/HTS-2.1/bin/HERest -A -D -T 1 > logs/durCDERest_after_tree4.log -C lists/trn_dur.cfg -H lsp_for_duration_modeling/TRI/hmms/HMM1.3/hmmdefs -N dur/TRI/hmms/HMM1.3/hmmdefs -M lsp_for_duration_modeling/TRI/hmms/HMM1.4 -R dur/TRI/hmms/HMM1.4 -m 1 -u tmvwdmv -w 3 -t 1500 100 5000 -S scp/aligned.scp -I mlfs/train_tri_nosp.mlf lists/real_tri_nosp.list lists/real_tri_nosp.list
The first re-estimation completed. However, I entercount the following error in the 2nd re-estimation.
ERROR [+7031] PutTransMat: Row 6 of transition mat is all zero
FATAL ERROR - Terminating program /usr/local/HTS-2.1/bin/HERest
The memory of the machine is relatively sufficient, about 8G. I will be very thankful if someone could help.
