Summary by CodeRabbit

  • New Features

    • Added Python build options for neural, detection, and spatial detection networks using model descriptions, archives, or model paths.
    • Added support for building segmentation parsers from model archives.
    • Preserved camera and replay-video workflows with optional FPS and resize settings.
    • Clarified spatial detection’s depth-source parameter as stereo.
  • Examples

    • Updated time-of-flight examples to use floating-point depth range values for colorization.

Review Change Stack

📝 Walkthrough

Walkthrough

The PR restores Python model-form overloads for pipeline nodes, updates SpatialDetectionNetwork argument naming, pins build and device dependencies, increments the project version, and changes ToF depth bounds to floating-point literals.

Changes

Python binding compatibility

Layer / File(s) Summary
Python model overloads
bindings/python/src/pipeline/node/DetectionNetworkBindings.cpp, bindings/python/src/pipeline/node/NeuralNetworkBindings.cpp, bindings/python/src/pipeline/node/SegmentationParserBindings.cpp
Bindings accept model descriptions, archives, and model strings through consolidated model-based build paths.
Spatial detection overloads
bindings/python/src/pipeline/node/SpatialDetectionNetworkBindings.cpp
Legacy model-form overloads are restored. The depth-source argument is named stereo, and the default resize mode is CROP.

Release and dependency updates

Layer / File(s) Summary
Release and dependency pins
CMakeLists.txt, .github/workflows/main.workflow.yml, bindings/python/external/pybind11_opencv_numpy, cmake/Depthai/*
The project version and pinned CI, submodule, device, and visualizer references are updated.

ToF examples

Layer / File(s) Summary
Floating-point depth bounds
examples/python/ToF/tof_*.py
Depth range values use floating-point literals with unchanged numeric values.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to ac928

The change is merge-ready after normal checks; the only follow-up is correcting a comment that describes a version identifier as a full commit hash, with no functional impact.

Poem

A rabbit checks each model door,
Archives, strings, and descriptions galore.
Pins line up in a tidy row,
ToF bounds float where numbers flow.
“Build clean,” says Bun, with a hop—
“The pipeline paths no longer stop!”

Learning: In depthai-core example code, do not set `ImageManip::Backend::GPU` unconditionally. The GPU backend is only available on RVC4 (not RVC2). Prefer leaving the backend as the default, or comment out the GPU backend selection and add a clear note explaining it is RVC4-only support (so the example won’t fail or mislead on RVC2).

Accept the submodule update.

Commit 7926f9a81cced260d16166437272e1491905230a exists. Its only change clears failed cv::Mat conversion errors so pybind11 can select another overload. No model-format binding is affected.
