ultralytics 8.3.245

v8.3.245 - `ultralytics 8.3.245` 2026 Docs footer and System metrics updates (#23095)

on Python PyPI

🌟 Summary (single-line synopsis)

Ultralytics 8.3.245 enhances training/run telemetry by reporting system hardware capacity (RAM + disk) and best model file size, plus a small docs footer refresh 🖥️📈📦

📊 Key Changes

• System metrics added to platform callbacks 🧰
  _get_environment_info() now reports:
  • Total RAM (GB) via psutil
  • Total disk capacity (GB) via shutil.disk_usage("/")
• Best model artifact size captured at training end 📦
  During on_train_end(), the callback records the best checkpoint file size (modelSize) and includes it in the final training-complete payload.
• Docs footer year updated (2025 → 2026) 🗓️
  MkDocs site copyright bump.
• (Minor) Comment-only fix for tensor shape annotations 🧩
  Clarifies tensor shapes after .view(-1) / .reshape(...) in attention/query-selection code comments (no runtime behavior change).

🎯 Purpose & Impact

• Better debugging + analytics context 🔍
  Knowing total RAM and disk makes it easier to interpret performance issues, out-of-memory errors, dataset caching behavior, and environment differences across machines.
• More visibility into deployment/storage footprint 🚀
  Tracking the best model file size helps with:
  • storage planning (especially in CI/HUB workflows)
  • comparing export/training variants
  • deployment constraints (edge devices, artifact limits)
• No model accuracy/training logic changes ✅
  Aside from telemetry and metadata updates, training/inference behavior remains effectively the same in this release.

What's Changed

• Fix incorrect shape comments in tensor operations by @raimbekovm in #23094
• ultralytics 8.3.245 2026 Docs footer and System metrics updates by @glenn-jocher in #23095
