KaldiFatalError during decoding phase #246

Open tanzyy96 opened 4 years ago

tanzyy96 commented 4 years ago

I wanted to try out the PASE Kaldi ASR experiment on the TIMIT dataset. The initial training phase was successful. However, during the decoding phase, the code abruptly ended with the following message:

run.pl: job failed, log is in /Project0550/zhiyang/pase/out_folder/dec/scoring/log/best_path.1.1.log

Any ideas?
