🌟 Summary (single-line synopsis)

Ultralytics v8.4.11 makes Ultralytics Platform training uploads far more reliable by adding retryable model uploads + metrics posting, plus a new reusable upload helper and docs 🚀📶

📊 Key Changes

• Robust Platform upload + metrics retries (PR #23538 by @glenn-jocher) 🔁
  • Added a new utility: ultralytics/utils/uploads.py with safe_upload() that supports retries, timeouts, and optional progress bars ⏳📦
  • Platform callback networking hardened:
    • _send() now retries transient failures, uses a longer timeout (30s), and does not retry most 4xx client errors (except common transient ones like timeout/rate-limit) 🛡️
    • _upload_model() now retries signed-URL retrieval and uses safe_upload() for the actual upload to cloud storage ☁️
  • Platform now receives only the remote cloud path (gcsPath) as modelPath (instead of accidentally sending a local filesystem path) ✅
  • Training end now uploads the best model with a progress bar enabled by default 📊
  • Added a new reference doc page for uploads utilities and linked it into the docs nav 📚
• Windows OpenVINO export test stability fix (PR #23528 by @lakshanthad) 🪟✅
  • Ensures OpenVINO export tests use unique output filenames on Windows to prevent file locking/collision issues in CI 🧪

🎯 Purpose & Impact

• Fewer failed Platform syncs during training due to flaky networks or transient API/upload hiccups 📶➡️✅
  Impact: your experiment tracking, logs, metrics, and model artifacts are more likely to show up correctly on the Ultralytics Platform.
• More reliable large checkpoint uploads (with retries + progress feedback) 📦⏫
  Impact: less manual re-running/re-uploading when training finishes, especially on slower or unstable connections.
• Cleaner, safer metadata sent to Platform 🧹
  Impact: Platform gets a downloadable cloud path, not a meaningless local path like C:\... or /home/....
• Improved CI stability on Windows for OpenVINO exports 🪟
  Impact: no change for most end users, but faster/cleaner releases and fewer flaky test failures.
