Decompress evaluator checkpoint

For facilitate the training of the generator, we provide a version of the checkpoints of CMR_evaluator that have been pretrained. We first need to decompress it.

tar -xzvf ./model/save_model_ad/10/*.tar.gz -C ./model/save_model_ad/10/

Train LAST

python run_reranker.py

Model parameters can be set by using a config file, and specify its file path at --setting_path, e.g., python run_ranker.py --setting_path config. The config files for the different models can be found in example/config. Moreover, model parameters can also be directly set from the command line.

Eval LAST model

python eval_last_model.py --reload_path='path/to/model/you/trained'
