Ultralytics v8.3.184 Release — System & Console Logging Upgrades for Better Training Visibility

Summary  
v8.3.184 delivers two major logging utilities—`SystemLogger` for real-time system metrics and `ConsoleLogger` for early, continuous training log capture—boosting observability, reliability, and integrations across YOLO11 workflows.

New Features

- SystemLogger (ultralytics.utils.logger.SystemLogger)
  - Collects CPU, RAM, disk I/O, network I/O, and NVIDIA GPU stats via `pynvml`.
  - Integrated via platform callbacks; samples metrics at epoch end.
  - PR: Fix missing async docs functions by [@glenn-jocher](https://github.com/glenn-jocher) in [#21760](https://github.com/ultralytics/ultralytics/pull/21760) and New SystemLogger class in [#21764](https://github.com/ultralytics/ultralytics/pull/21764)

- ConsoleLogger (ultralytics.utils.logger.ConsoleLogger)
  - Captures stdout/stderr and Ultralytics logger output from trainer initialization.
  - Deduplicates noisy lines and progress bars; streams to file (`train.log`) or an API.
  - PR: Add ConsoleLogger class by [@glenn-jocher](https://github.com/glenn-jocher) in [#21761](https://github.com/ultralytics/ultralytics/pull/21761)

- Platform callbacks module
  - `ultralytics.utils.callbacks.platform` registers start/stop hooks for console capture and metrics collection.
  - See related updates in the above PRs.

Improvements

- Metrics type consistency
  - Checkpoints now store metrics as plain Python floats (instead of NumPy types) for better serialization and tool compatibility (Ultralytics HUB, W&B, TensorBoard, JSON/CSV/YAML).
  - PR: Update metrics.py from numpy to floats by [@glenn-jocher](https://github.com/glenn-jocher) in [#21773](https://github.com/ultralytics/ultralytics/pull/21773)

- Cleaner CI progress bars
  - Throttled TQDM updates on GitHub Actions for quieter logs; no change for local runs.
  - PR: Cleaner TQDM in CI by [@glenn-jocher](https://github.com/glenn-jocher) in [#21775](https://github.com/ultralytics/ultralytics/pull/21775)

- Documentation updates
  - API docs now include async functions and a reference for the new NDJSON-to-YOLO converter.
  - New docs pages for platform callbacks and logger utilities.
  - PR: Fix missing async functions in Docs by [@glenn-jocher](https://github.com/glenn-jocher) in [#21760](https://github.com/ultralytics/ultralytics/pull/21760)

Bug Fixes

- Addressed missing async functions in API docs (see [#21760](https://github.com/ultralytics/ultralytics/pull/21760)).

Purpose & Impact

- Better training visibility and debugging
  - `SystemLogger` provides actionable telemetry (CPU/GPU/memory/disk/network) to diagnose bottlenecks and environment issues.

- More reliable, complete logs
  - `ConsoleLogger` starts early, deduplicates noise, and streams logs for stable, searchable records locally or via APIs.

- Smoother integrations and exports
  - Float metrics prevent serialization errors and improve compatibility across tools.

- Cleaner CI pipelines
  - Reduced log spam and fewer rate-limit risks on GitHub Actions.

- Documentation catch-up
  - Clearer API references and discoverability for new utilities and data conversion tools.

Quick Start

- Capture console output to file:

```python
from ultralytics.utils.logger import ConsoleLogger

logger = ConsoleLogger("train.log")
logger.start_capture()
print("Training starts...")
logger.stop_capture()

```

- Fetch system metrics on demand:

```python
from ultralytics.utils.logger import SystemLogger

syslog = SystemLogger()
print(syslog.get_metrics()) # {'cpu': ..., 'ram': ..., 'disk': {...}, 'network': {...}, 'gpus': {...}}

```
