What it is

Dowel is a logging tool designed specifically for machine learning researchers. It simplifies the process of logging data by supporting various outputs like CSV, TensorBoard, and text logs with just one function call.

Dowel stands out as a lightweight, easy-to-use logger that simplifies the process of logging machine learning experiment results to various formats without requiring extensive setup.

When it fits — and when it doesn’t

A good fit for

  • Researchers who need a simple and efficient way to log their machine learning experiments.

  • Developers working on projects that require logging to multiple formats without complex setup.

Look elsewhere if

  • Projects requiring real-time data streaming or complex logging configurations beyond basic output formats.

  • Teams needing cloud-based logging solutions with advanced features like automatic scaling and monitoring.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited language support beyond Python

    Primary development is focused on Python, with other languages having limited or no official support.

  2. 02

    Documentation lacks depth and examples for advanced use cases

    The documentation provides basic usage but fails to cover complex scenarios and best practices in detail.

  3. 03

    Performance degradation with high-frequency logging

    Logging at a very high frequency can lead to significant performance overhead, impacting the speed of machine learning experiments.

  4. 04

    Community and support are relatively small

    The user community is not large, leading to fewer contributions and slower response times for issues and feature requests.

What it does well

  • Supports multiple output formats with a single function call.

  • Easy integration into existing machine learning workflows.

  • Lightweight and efficient for logging purposes.
