What do we need to do to train a model now?

• Change data_root in configs/config.json file
• In train.py, we need to change 2 lines:
  • config.vocab_type = 'xxx' (xxx in ['ctc', 'attention', 'joint'])
  • model = XxxModel(config)

Data sample

• Please take a look at data/val.json file, the data in this file is a dictionary with following structure:

{    
    path1: label1, 
    path2: label2,
    ...
    pathn: labeln
}
