Welcome to Neptune!

Neptune is a light-weight experiment management tool that helps you keep track of your machine learning experiments.

Use Neptune to log hyperparameters and output metrics from your runs, then visualize and compare results. Automatically transform tracked data into a knowledge repository, then share and discuss your work with colleagues.

  • Neptune fits in any workflow, ranging from data exploration and analysis, decision science to machine learning and deep learning.

  • Neptune works with common technologies in the data science domain: Python, Jupyter Notebooks, and R, to mention a few.

  • It integrates with other tracking tools such as MLflow and TensorBoard or Sacred and many other machine learning and deep learning frameworks.

  • It integrates seamlessly with your machine learning infrastructure, be it AWS, GCP, Kubernetes, Azure, or on-prem machines.

  • The Neptune Python Library is an open source package that allows you to integrate your Python scripts with Neptune. Once you have integrated with Neptune, you can:

    • Create and track experiments

    • Manage and run experiments

    • Fetching experiment and project data

Track, Organize, Collaborate

The Neptune workflow comprises three iterative phases:

  • Track all objects in the data science or machine learning project. It can be model training curves, visualizations, input data, calculated features and so on. The snippet below presents an example of integration with Python code.

    import neptune
    
    neptune.init('shared/onboarding', api_token='ANONYMOUS')
    neptune.create_experiment()
    
    neptune.append_tag('minimal-example')
    n = 117
    for i in range(1, n):
        neptune.send_metric('iteration', i)
        neptune.send_metric('loss', 1/i**0.5)
        neptune.set_property('n_iterations', n)
    

    Note

    The api_token belongs to the public user Neptuner. After running the code, your experiment will appear on the experiments dashboard.

    For more information, see Experiment Tracking.

  • Organize the structure of your project:

    • Code

    • Notebooks

    • Experiment results

    • Model weights

    • Meeting notes

    • Reports

    Everything is in one place, accessible from the application or programmatically. Neptune exposes a Query API, that allows users to access their Neptune data right from the Python code.

    For more information, see Experiments View.

  • Collaborate in the team:

    • Share your experiments

    • Compare results

    • Comment and communicate your work

    • Use widgets and mentions to show your progress

    • Speak your language in our data-science focused interactive wiki!
