when I run the following command
python train.py --data=configs/data.json --vocab=configs/vocab.json --training=configs/training.json --model=configs/model.json --output=results/full/
the result is

Hi, later I found it is a problem with the input data. I re-ran the program and it worked.
Also I modify your work a little bit to try adaptive attention and it worked pretty well. Brilliant code by you. Thanks!

Would you like to send me your modified code and I will test it. Let's work together to write a paper, publish it, and achieve retrieval by EI or SCI. OK？
