Hello,
It is fantastic, so cool.
Following to your guide, I try to test pre-trained model but I am not sure my result is right or not.

Step1. which path do these arguments(--exp, --reload) have? "Mine" command line is right, or not? if excite with mine, I don't get any in "out" directory. If you are possible, I hope you show example.
(Guide) python Scripts/prediction/generate_annotation.py --exp <path_to_corresponding_experiment> --reload <path_to_checkpoint> --output_dir <path_to_store_predictions>
(Mine) (env) charles@charles-ubuntu:~/Documents/polyrnnpp/polyrnn-pp-pytorch/code$ python Scripts/prediction/generate_annotation.py --exp Experiments/rl.json --reload ../models/rl_epoch1_step3000.pth --output_dir out/

Step2. which path do these arguments(--pred,--output) have? If you are possible, I hope you show example.
(Guide) python Scripts/get_scores.py --pred <path_to_preds> --output <path_to_file_to_save_results>
(Mine) (env) charles@charles-ubuntu:~/Documents/polyrnnpp/polyrnn-pp-pytorch/code$ python Scripts/get_scores.py --pred out/ --output out/
