DVCLive allows you to easily add experiment tracking capabilities to your TensorFlow projects.

About TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. It has a comprehensive, flexible ecosystem of tools, libraries, and community resources that lets researchers push the state-of-the-art in ML and developers easily build and deploy ML-powered applications.


To start using DVCLive you just need to add a few lines to your training code in any TensorFlow project.

πŸ’‘ If you prefer the Keras API, check the DVCLive - Keras page.

You need to add dvclive.log() calls to each place where you would like to log metrics and one single dvclive.next_step() call to indicate that the epoch has ended.

To ilustrate with some code, extracted from the official TensorFlow guide:

for epoch in range(epochs):
    start_time = time.time()
    for step, (x_batch_train, y_batch_train) in enumerate(train_dataset):
        with tf.GradientTape() as tape:
            logits = model(x_batch_train, training=True)
            loss_value = loss_fn(y_batch_train, logits)
        grads = tape.gradient(loss_value, model.trainable_weights)
        optimizer.apply_gradients(zip(grads, model.trainable_weights))
        train_acc_metric.update_state(y_batch_train, logits)

+    dvclive.log("train/accuracy", float(train_acc_metric.result())

    for x_batch_val, y_batch_val in val_dataset:
        val_logits = model(x_batch_val, training=False)
        val_acc_metric.update_state(y_batch_val, val_logits)
+    dvclive.log("val/accuracy", float(val_acc_metric.result())

+    dvclive.next_step()

This will generate the metrics logs and summaries as described in the Get Started.

πŸ’‘Without requiring additional modifications to your training code, you can use DVCLive alongside DVC. See DVCLive with DVC for more info.
