    let teams = vec![team1.clone(), team2.clone()];

    let env = Env::default(); // == EnvBuilder::default().model(ModelKind::PlackettLuce).build()
    let draw_prob = env.predict_draw(&teams)?;
    let win_rate = env.predict_win(&teams)?;
    println!("teams: {teams:?}");
    println!("draw probability: {draw_prob}, win rate: {win_rate:?}");

    let new_rate = env.rate(&GameResult::new(teams.clone(), vec![1, 2]))?;
