I’m trying to train a speech recognition model using Kaldi. I’ve successfully run the steps/nnet3/align.sh script, but the expected ali.1.gz file is not being created in the exp/chain/tree_sp directory.

I’ve checked the terminal output and log files within the exp/chain/tree_sp/log directory, but there are no error messages. The script seems to run without issues, but the desired output is missing.

Can you suggest potential causes for this issue or steps to debug further? How to solve this?

I’ve run the steps/nnet3/align.sh script successfully (no errors in the terminal or log files).
I’ve checked for the existence of ali.JOB.gz files in the exp/chain/tree_sp directory but they are not present(not created)

I expect the steps/nnet3/align.sh script to successfully create the ali.1.gz file (or multiple ali.JOB.gz files) in the exp/chain/tree_sp directory. This file is essential for the subsequent training steps in the Kaldi pipeline.
