DeepLabCut 3.0.1 - a stability release with a major documentation overhaul and a new structured configuration system.

Highlights

  • Comprehensive documentation audit — The user guide has been thoroughly reviewed, updated, and improved. Please check out:
  • Our updated user guide, which is restructured for better readability and updated to reflect the latest API and features.

  • Our brand-new developer documentation site, which provides full API references, architecture guides, and developer onboarding material.

  • Structured & validated configurations — The config system has been migrated to typed Pydantic models. Existing config.yaml files remain fully compatible, but configs are now schema-validated on load with clear error messages for invalid entries. Some user-benefits include:

  • ProjectConfig: load and save your config.yaml with full schema validation — typos, wrong types, or invalid values are caught immediately with clear error messages.
  • Pretty-printing: call cfg.print() or pretty_print(cfg) to inspect any config in a readable tree.
  • Change-tracking: DLCVersionedConfig tracks which fields have been modified since the config was loaded from YAML, so when saving back to disk, log_changes() can report exactly what was changed.
  • Dict-like compatibility: existing code that accesses config keys like a dict still works.
  • Auto-aliasing of old field names: renamed keys are silently mapped, so older config files load without manual edits.
