photon: a modern experiment tracker in pure Rust

photon is a fast and modern experiment tracker written in Rust.

Example

fn main() {
    let mut run = photon::Run::builder()
        .start()
        .expect("failed to start run");

    println!("Run: {}", run.id());

    // Simulate a training loop
    for step in 0..100_000_000 {
        let loss = 1.0 / (1.0 + step as f64 * 0.05);
        let accuracy = 1.0 - loss;

        run.log("train/loss", loss, step).unwrap();
        run.log("train/accuracy", accuracy, step).unwrap();

        if step % 10 == 0 {
            let lr = 0.001 * 0.95_f64.powi(step as i32 / 10);
            run.log("train/lr", lr, step).unwrap();
        }
    }

    println!("Logged: {} points", run.points_logged());

    let stats = run.finish().expect("finish failed");
    // etc
}
