How to run:

• Python 3.7, Pytorch 0.4+
• Download the processed dataset from: https://drive.google.com/file/d/1EUuEMBSlrlnf_J2jcAVl1v4owSvw_8ZF/view?usp=sharing , or you can download the original FINISHED_FILES from: https://github.com/JafferWilson/Process-Data-of-CNN-DailyMail , and process by yourself.
• Modify the path in prepare_data.py then run it: python prepare_data.py
• Training: python -u main.py | tee train.log
• Tuning: modify main.py: is_predicting=true and model_selection=true, then run "bash tuning_deepmind.sh | tee tune.log"
• Testing: modify main.py: is_predicting=true and model_selection=false, then run "python main.py you-best-model (say cnndm.s2s.gpu4.epoch7.1)", go to "./deepmind/result/" and run $ROUGE$ myROUGE_Config.xml C, you will get the results.
• The Perl Rouge package is enough, I did not use pyrouge.
