:new_button: What’s New

Key Features & Improvements

  • Lighter File Downloads

    • We’ve replaced the previous PyTorch-based file download mechanism with a standard Python approach—no more extra PyTorch dependency if you just want to download files!
    • See the implementation by @glenn-jocher in PR #21563.

  • Unified Download Progress Reporting

    • Progress bars for downloads are now consistent and reliable, powered by a single TQDM instance—regardless of how you install or run Ultralytics.
    • Also released in PR #21563.

  • Updated Documentation

    • We clarified OBB documentation in simple-utilities.md thanks to a contribution from @mgcrea.
    • See the details in PR #21555.
    • Documentation for the Annotator class is now up to date, making it easier for you to get started without confusion.
