v8.3.185 - Fix TQDM Rich bars to 10 width (#21789)

on Python PyPI

🌟 Summary

Improved training progress bars for Rich TQDM users, plus robustness and CI/documentation polish for a smoother overall experience. 🎛️✨

📊 Key Changes

• Progress bars (priority)
  • Fixed Rich-based TQDM bars to always render clearly: Console width set to 200 and bar width set to 10 when YOLO_TQDM_RICH=true. ✅
  • Resolves missing or truncated bars seen at width 80 in some terminals/CI/Colab.
  • Version bump to 8.3.185.
• Data loading reliability
  • YOLODataset now defaults to 3 image channels (RGB) if not provided.
  • yolo_bbox2segment() explicitly sets channels=3 to avoid missing-key errors.
• CI improvements
  • GPU CI job switches to uv for environment management: uv pip install and uv pip list.
  • Removes extra installs (e.g., pynvml, tensorrt, onnxruntime-gpu) to streamline runs.
• Docs and maintenance
  • Updated link-check workflow to correctly exclude CI files.
  • Clarified SystemLogger.get_metrics() docstring with accurate Python examples.
  • Neural Magic integration links now point to internal docs for a smoother reading experience.

🎯 Purpose & Impact

• Better UX for progress tracking
  • Rich TQDM users get consistent, readable progress bars across terminals and notebooks. 🙌
  • Default users are unaffected unless YOLO_TQDM_RICH=true is set.
• More robust workflows
  • Prevents crashes when dataset channel info is missing; safer bbox-to-segmentation conversion. 🛡️
• Faster, cleaner CI
  • Quicker, more reproducible tests with uv; note some GPU backend tests may have reduced coverage. ⚡
• Clearer docs
  • Easier navigation and more accurate examples for contributors and users. 📚

Enable Rich progress bars:

• CLI: YOLO_TQDM_RICH=true yolo train ...
• Python:

import os
os.environ["YOLO_TQDM_RICH"] = "true"
from ultralytics import YOLO
YOLO("yolo11n.pt").train(data="coco8.yaml", epochs=1)
