What’s New

The last 10 stable releases of WeightsLab, newest first. Each card links to its full release notes on GitHub, where the complete “What’s Changed” commit list lives.

Note

Only stable releases appear here. Every tag also publishes a vX.Y.Z.devN pre-release to TestPyPI for verification; those are build plumbing rather than user-facing changes.

Tip

Upgrade with pip install --upgrade weightslab. Setting up for the first time? Start at Quickstart.

What’s New ?

New Features

  • Runs management — unified UI to browse, organize, rename, and inspect experiment runs.

  • Error bands & outlier highlighting — curves now display statistical bands and visually emphasize anomalous steps.

  • Relabelling export — export tagged/annotated data to external tools (CVAT, V7, etc.) for downstream relabelling workflows.

  • Integrated OpenCode Agent — full agent loop support (code generation, training, monitoring, report creation) directly inside WeightsLab.

  • Multimodal data support — unified handling of images, videos, metadata, and structured signals.

  • Automatic resource monitoring — GPU/CPU/RAM usage tracked and surfaced during training and agent operations.

  • Dynamic HTML report generation — multi‑section experiment reports with plots, dataset analysis, training insights, and test results.

Fixes & Improvements

  • Agent stability improvements — better token management, reliable process detaching, consistent initialization, and workspace‑safe lifecycle.

  • Plotting upgrades

  • Correct zoom behavior across large step ranges

  • Bright color palettes in light mode

  • Outlier visualization improvements

  • Right‑click actions: BBS, highlight, hide curve, step notes, load weights, color changes

  • Signal pipeline fixes — improved decimation, preservation of special points, kernel stability, and classification logic.

  • DB performance improvements — safer handling of large histories, better compaction, and reduced memory pressure.

  • Tag painter fixes — more reliable tagging, discarding, and annotation workflows.

  • Workspace & session recovery — restart window reloads ongoing sessions, history, and conversation context.

  • UI polish

  • Search bar cleanup

  • Agent input bar sync

  • Regex‑based research plots

  • Updated sandbox modes

  • Improved multimodal previews

  • Cross‑platform testing — validated on Windows, Ubuntu, Jupyter, and Google Colab.

Developer Experience

  • Unified configuration — examples now rely on clean cfg files instead of hardcoded defaults.

  • Improved CLI — better agent commands, clearer /clear and /compact, stable loop behavior.

  • Changelog & documentation updates — new “What’s New”, migration notes (W&B / v51 / 3LC), updated examples, and expanded UI documentation.

Experimental & Advanced

  • Video generation workflows — multi‑input styles, real‑world models, and dataset‑driven video tasks.

  • Image generation workflows — PyTorch‑based generation paths integrated with agent prompts.

v1.5.0

  • PR #285

    • This PR introduces Google Collabs fixes and new integration:

    • Google Collab fixes

    • Jupyter Notebook Integration

    • Live notebook on-training allowing user to query, analyze, and ask agent to generate code to analyze ongoing experiment from the UI

    • Report generation with agent from code, CLI, or UI

v1.4.2

  • PR #283

    Summary

    • Wraps the “Install from TestPyPI/PyPI (wait until indexed)” + “Verify package import” steps in both test-install-from-pip-dev-release and test-install-from-pip-main in a single retried unit (nick-fields/retry@v3, max_attempts: 3, retry_on: any).

    • Guards against transient failures unrelated to the package itself: the registry hasn’t finished indexing a fresh upload yet, or a one-off network blip during install/import.
