How to run training:

  1. Follow data generation instruction from https://github.com/abisee/cnn-dailymail
  2. Run start_train.sh, you might need to change some path and parameters in data_util/config.py
  3. For training run start_train.sh, for decoding run start_decode.sh, and for evaluating run run_eval.sh

Note:

  • It is tested on pytorch 0.4 with python 2.7
  • You need to setup pyrouge to get the rouge score
