The first one was added on 2019-02-01.

asr_train.py is in espnet/bin/asr_train.py, which invokes espnet.asr.pytorch_backend.asr.train.

The model is from espnet.nets.pytorch_backend.e2e_asr.E2E.

The encoder type vggblstm, 3 layers, hidden dim, 1024, proj dim 1024, subsampling 1_2_2_1_1.

Command is:
