Running the code

0. Install all dependencies mentioned above

1. Generate charged dataset for training (NBA dataset is available on [44])

python simulator.py --seed 0 --num_sample 5000 --filename train.npz
python simulator.py --seed 1 --num_sample 1000 --filename test.npz
python simulator.py --seed 2 --num_sample 1000 --filename valid.npz

2. Train the model

bash train.sh

3. Evaluate the model

bash eval.sh
