## Usage

### Loading the Model

```python
import torch
from moml.models.mgnn.djmgnn import DJMGNN

# Load the model
model = DJMGNN(
    in_node_dim=11,
    in_edge_dim=0,
    hidden_dim=128,
    n_blocks=3,
    layers_per_block=6,
    node_output_dims=3,
    graph_output_dims=19,
    energy_output_dims=1,
    jk_mode="cat",
    dropout=0.2,
    use_supernode=true,
    use_rbf=true,
    rbf_K=32
)

# Load the checkpoint
checkpoint = torch.load("path/to/pytorch_model.pt", map_location="cpu")
model.load_state_dict(checkpoint["model_state_dict"])
model.eval()
```

### Making Predictions

```python
# Assuming you have a molecular graph 'data' (torch_geometric.data.Data object)
with torch.no_grad():
    output = model(
        x=data.x,
        edge_index=data.edge_index,
        edge_attr=data.edge_attr,
        batch=data.batch
    )
    
    # Extract predictions
    node_predictions = output["node_pred"]      # Node-level predictions
    graph_predictions = output["graph_pred"]    # Graph-level predictions
    energy_predictions = output["energy_pred"]  # Energy predictions
```

## Model Performance

This is the base DJMGNN model trained on QM9, SPICE, and PFAS datasets.
