                               [--prefix_path PREFIX_PATH]
                               [--hidden_size HIDDEN_SIZE]
                               [-e EPOCHS_TO_TRAIN] [-b BATCH_SIZE]
                               [-lr LEARNING_RATE] [-a ALPHA]
                               [-neg NUM_NEG_SAMPLES] [-o OPTIONS]
                               [--seed SEED]

optional arguments:
  -h, --help            show this help message and exit
  --data_path DATA_PATH
                        Directory to load data.
  --save_path SAVE_PATH
                        Directory to save data.
