Instructions and Navigations

All of the code is organized into folders. For example, chapter - 1.

The code will look like the following:

model.eval()
_, pred = model(data.x, data.edge_index).max(dim=1)
correct = float(pred[data.test_mask].eq(
    data.y[data.test_mask]).sum().item())
accuracy = correct / data.test_mask.sum().item()
print(f'Accuracy: {accuracy:.4f}')

Create conda environment

conda create -n applied-graph-nn-book python=3.12
