The decoder, i.e., the prediction network, is from https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=9054419 (Rnn-Transducer with Stateless Prediction Network)
You can use the following command to start the training:
cd egs/aishell/ASR
export CUDA_VISIBLE_DEVICES="0,1,2,3,4,5,6,7"
./transducer_stateless/train.py \
--world-size 8 \
--num-epochs 30 \
--start-epoch 0 \
--exp-dir transducer_stateless/exp \
--max-duration 250 \
--lr-factor 2.5
