Jan 1, 2026January 2026 delivered a focused set of UX enhancements, expanded analytics tooling, and stronger release hygiene for talmolab/sleap. The UI overhaul for training/inference introduced a Frame Target Selector with side panel, preview, and collapsible advanced settings, backed by comprehensive tests; a new Size Distribution widget enables size analytics and frame navigation; unified CLI and sleap-io integration streamline workflows; and installation/docs improvements reduce setup friction. Major bug fixes addressed unintended video deletions, WandB login state handling, and conversion of predictions to user instances, contributing to more reliable training runs and analytics reporting. The month also increased test coverage, modernized dev tooling per PEP 735, and delivered a cohesive, business-focused release.

Dec 1, 2025December 2025 monthly summary for talmolab/sleap focusing on business value and technical accomplishments. Key features delivered: - Training GUI and Model Configuration Enhancements: ~55x faster config loading via lazy loading and optimized startup; enhanced UNet info display with channel validation; improved model config editor; per-head feature channel visualization for faster validation and iteration. - Sleap-nn-track accuracy improvement: ensure tracking_target_instance_count is set when post_connect_single_breaks is enabled to align with max_tracks, improving tracking reliability. - Delete predictions on user-labeled frames: capability to delete predictions on frames with user labels (unlinked-only or all) to reduce clutter and maintain data hygiene. - Startup banner: added a startup banner showing version, platform, Python and optionally PyTorch/GPU status for immediate startup feedback. - Stability and reliability enhancements: improved logging and error handling; YAML error recovery; various UI/config hardening (pre-population fixes, rotation field visibility improvements, and crop-size UI handling). Major bugs fixed: - Crash prevention when deleting unused tracks: guard against null instances to prevent crashes. - Rotation custom angle field visibility: hide the custom rotation field when a preset is selected to improve UI consistency. - Training config form not pre-populating from selected config: ensure updates propagate correctly to the form after selection. - Hide crop size field for non-cropping model types: crop UI now conditionally hidden to reflect model semantics. - Fix ID model config detection and optimize training dialog: robust rapidyaml parsing for ID models and lazy tab creation for performance. - Improved logging and error handling: structured logging levels and YAML error recovery to avoid crashes and improve debugging. Overall impact and accomplishments: - Dramatically improved developer and user experience through faster configuration load times, more reliable tracking, and cleaner user workflows. - Strengthened product reliability with stability hardening, better error handling, and more robust startup diagnostics. - Expanded testing and investigation capabilities with Claude Code skills and automated GUI testing workflows, contributing to higher quality releases. Technologies/skills demonstrated: - Python performance optimization (numpy-based computations, rapidyaml lazy loading, OmegaConf fallback) and UI refactors. - Qt GUI development and automated GUI testing (screenshot-based validation). - Sleap-nn integration, WandB configuration persistence, and GPU/CPU status detection in startup diagnostics. - Robust logging, YAML handling, and configuration management best practices.
