Overview
This week focuses on the AnanaCare Relabel project, with emphasis on automating the setup process and planning the Undo/Redo functionality.
Week Summary
Week 27 delivered a strong shift from prototype-level scripts to a more production-ready ML control plane. Across the week, the core job lifecycle was established end-to-end (start, monitor, logs, stop), then extended with Hugging Face remote log polling, model promotion workflow, and better process safety for long-running training tasks.
Key outcomes from this week:
- Built and validated the MVP Training Control Plane (FastAPI backend + Svelte dashboard) with live local job execution and log visibility.
- Added remote Hugging Face job log ingestion into backend polling, improving observability for cloud runs.
- Implemented model promotion flow (
/api/promote/{trial_id}) to transition from best trial parameters to reproducible final training. - Improved reliability and UX around results exploration, including dynamic version discovery and version-aware HiPlot rendering.
- Hardened process lifecycle behavior using
psutilto better terminate child processes and reduce zombie-process risk.
Notable context:
- Day 4 (March 19) was a light/non-technical entry due to Ugadi.
Challenges and follow-ups identified during the week:
- Need stronger persistence for job metadata (in-memory registry is still a limitation).
- Potential race conditions around concurrent promotion/sync operations need backend locking.
- HiPlot behavior for large trial sets and cross-browser blob handling still needs extra hardening/testing.
Overall, the week closed with meaningful momentum: the platform now supports the full loop of experiment execution, monitoring, comparison, and promotion, with clearer paths toward production stability in the next iteration.
