Neptune + Keras integration

Experiment tracking for Keras-trained models.

What will you get with this integration?

• Log, organize, visualize, and compare ML experiments in a single place
• Monitor model training live
• Version and query production-ready models and associated metadata (e.g., datasets)
• Collaborate with the team and across the organization

What will be logged to Neptune?

• hyperparameters for every run,
• learning curves for losses and metrics during training,
• hardware consumption and stdout/stderr output during training,
• TensorFlow tensors as images to see model predictions live,
• training code and Git commit information,
• model weights,
• other metadata

Example charts in the Neptune UI with logged accuracy and loss

Example

On the command line:

pip install neptune-tensorflow-keras

In Python:

import neptune
from neptune.integrations.tensorflow_keras import NeptuneCallback
from neptune import ANONYMOUS_API_TOKEN

# Start a run
run = neptune.init_run(
    project="common/tf-keras-integration",
    api_token=ANONYMOUS_API_TOKEN,
)

# Create a NeptuneCallback instance
neptune_cbk = NeptuneCallback(run=run, base_namespace="metrics")

# Pass the callback to model.fit()
model.fit(
    x_train,
    y_train,
    epochs=5,
    batch_size=64,
    callbacks=[neptune_cbk],
)

# Stop the run
run.stop()
