```auto
program: Source/hyperparameter_tuning.py

method: grid  

metric:
  name: val_loss
  goal: minimize  

parameters:
  num_heads:
    values: [2, 3, 4]
  EGAT_Layers:
    values: [2, 3, 4]
  hidden_dim:
    values: [32, 64, 128]

command:
  - ${env}
  - ${interpreter}
  - ${program}
  - "--config"
  - "Example/Molecule/QM9.yaml"
  - "--data_path"
  - "Example/Generated_Data"
  - "--save_path"
  - "${args}"

```

I was thinking about something like this

```auto
  - "--data_path"
  - "Example/Generated_Data/num_heads_${num_heads}_EGAT_${EGAT_Layers}_hidden_${hidden_dim}"
  - "--save_path"
  - "Example/Generated_Data/num_heads_${num_heads}_EGAT_${EGAT_Layers}_hidden_${hidden_dim}"

```

Does this make sense?
