, the feats_normalize flag (set to global_mvn in default) is not passed to espnet2.bin.asr_train.
This causes errors in later espnet2.bin.aggregate_stats_dirs,
(2) Even if I pass "--normalize $feats_normalize" to espnet2.bin.asr_train, when feats_normalize is global_mvn, this produces errors. It seems that global mean and var are not computed and saved to .npz files. When I pass in utterance_mvn, the code is fine.

Hi @zqwang7 , in (1), it is not supposed to pass normalize flag, because it is the collect stats.
I assume the error (2) is because no stats were generated in collect stats. In your asr_config, do you have something like "extract_feats_in_collect_stats"?

I obverve two problems:
