AI Assist no longer crashes on overlapping shapesv7.0.4

Changelog

New features and improvements in Labelme.

  1. 2026

  2. FIXv7.0.4

    AI Assist no longer crashes on overlapping shapes

    Labelme v7.0.4 fixes an AI Assist / AI Box crash that hit on older Pillow versions when a new detection overlapped an existing polygon or oriented-rectangle shape.

  3. FIXv7.0.3

    Deleting from the annotation list no longer crashes your next shape

    Labelme v7.0.3 fixes a crash where deleting an annotation from the list's right-click menu brought the app down on your next shape. It also stops AI polygon output from choking on very thin detections.

  4. FEATUREv7.0

    Dark mode, and a theme that follows your system

    Labelme v7 adds a color theme setting with System, Light, and Dark. Dark mode is new, System tracks your OS appearance, and the switch applies live without a restart.

  5. FEATUREv7.0

    Annotate past the edge of the image

    A BETA preview in Labelme v7. Place polygon and shape points beyond the image boundary, so objects that run off the frame keep their true geometry instead of being clamped to the edge.

  6. FEATUREv7.0

    See labels on the canvas, not just in the side panel

    A BETA preview in Labelme v7. Draw each shape's label text directly on the canvas so you can read what's what without cross-referencing the polygon list.

  7. FEATUREv7.0

    A real Settings dialog, not a text file

    Labelme v7 replaces the open-the-YAML-in-an-editor preference flow with a Settings dialog that applies changes live, preserves your comments, and lets you pick the language in-app.

  8. FEATUREToolkit v0.3.0

    YOLO-OBB export and import in the Toolkit

    The toolkit now converts oriented bounding boxes both ways. Export a Labelme dataset to YOLO-OBB for YOLOv8-OBB training, and import a YOLO-OBB dataset back into editable Labelme shapes.

  9. FIXv6.3.1

    Switching draw modes mid-shape, without the crash

    A three-click sequence used to crash Labelme whenever you changed draw modes mid-shape. v6.3.1 fixes it, and stops empty shapes (zero-area rectangles, zero-length lines, single-point polygons) from getting saved into your annotation files.

  10. FEATUREv6.3

    AI-assisted annotation for crowd objects, without the duplicates

    Two suppression passes in Labelme v6.3 stop AI-Box, AI-Points, and AI-Text from stacking redundant predictions on the same object, whether they came from nested SAM granularities or from regions you've already labeled.

  11. FEATUREv6.2

    AI annotation outputs circles and rectangles, not just polygons

    Pick the output shape for AI-Points and AI-Box: polygon, mask, rectangle, oriented rectangle, or circle. Fitted to the SAM mask, no post-export conversion.

  12. FEATUREv6.2

    Multi-select labels in Labelme

    Select many annotations at once and apply the same edit to all of them. Ctrl/Cmd+A grabs every shape on the image, range-select works in the label list, and hide/show propagates across the whole selection as one undoable step.

  13. FEATUREv6.2

    Oriented rectangle, a rotated bounding box for off-angle objects

    A new shape type in Labelme v6.2. Three clicks to draw, corner drag to resize, edge midpoint to rotate, with an arrow on the canvas so the heading is never ambiguous.

  14. FEATUREv6.1

    AI model downloads show progress, and you can cancel

    The first AI click of a fresh install used to freeze the app for minutes while the model downloaded in silence. v6.1 shows a progress bar with bytes, ETA, and a cancel button.

  15. FEATUREv6.1

    A unified AI toolbar, two tools instead of four

    Labelme v6.1 collapses four near-identical AI buttons into AI-Points and AI-Box, each with a polygon-or-mask output toggle. A separator between manual and AI tools makes the right button easier to find when you haven't opened the app in a week.

  16. FEATUREv6.1

    SAM3 AI-Box mode, one prompt for a whole crowd

    Drag a single bounding box around a cluster and SAM3 returns one shape per instance inside it. Built for parking lots, shelves, microscopy, and anything else where every visible object is the same kind of thing.

  17. FEATUREv6.0

    Annotation JSON files store image paths, not pixels

    Labelme v6 stops base64-embedding the image inside every annotation JSON by default. Files get an order of magnitude smaller, diffs become readable, and version control stops choking on the binary blob.

  18. FEATUREv6.0

    Auto-save is on by default

    Labelme v6 saves annotations as you work. The most common way to lose hours of labeling — forgetting to Ctrl+S before closing — is gone for new installs.

  19. FEATUREv6.0

    Large image and TIFF support for satellite and aerial imagery

    Labelme v6 opens multi-gigapixel images and float32 GeoTIFFs that v5 refused to load. Pan, zoom, and annotate a 26,000 x 22,000 px aerial tile without the app locking up.
