All 65 tests still pass on PyQt6 6.11; the full app constructs and renders headlessly via QT_QPA_PLATFORM=offscreen. What changed ------------ - Dependency pins: PyQt5>=5.15 -> PyQt6>=6.7 (requirements.txt, setup.py) - Bulk import rewrite: `from PyQt5...` -> `from PyQt6...` (28 files) - Symbol relocations: * QAction moved from QtWidgets to QtGui (annotator_window.py) * QDesktopWidget removed -> QGuiApplication.primaryScreen() (snake_game.py) - Enum namespacing (Qt6 requires fully-qualified names everywhere): * Qt.AlignmentFlag / MouseButton / KeyboardModifier / Key * Qt.PenStyle / BrushStyle / CursorShape / GlobalColor * Qt.WindowType / WindowModality / FocusPolicy / TransformationMode * Qt.ItemDataRole / ItemFlag / ContextMenuPolicy / ScrollBarPolicy * Qt.TextFormat / TextInteractionFlag / MatchFlag / CheckState * QMessageBox.StandardButton / .Icon / .ButtonRole * QDialog.DialogCode, QFileDialog.AcceptMode / FileMode / Option * QAbstractItemView.SelectionMode / SelectionBehavior / EditTrigger * QHeaderView.ResizeMode, QSlider.TickPosition * QPainter.RenderHint, QImage.Format.Format_* * QDialogButtonBox.StandardButton / .ButtonRole * QKeySequence.StandardKey - Modern event API in image_label.py: event.pos()/.x()/.y() -> event.position() returning QPointF end-to-end. Scrollbar setValue() takes int() of the QPointF delta (the boundary). - Removed dead workaround in annotator_window.py: clearing WindowContextHelpButtonHint from dialog flags. Qt6 already suppresses this; the flag itself was removed. - exec_() -> exec() in main.py entry point. - CI: add libegl1/libgl1 to the Linux apt-install list (Qt6 needs them). - Docs: CLAUDE.md, README.md, docs/02_architecture_constraints.md updated to reflect PyQt6 and the relaxed Linux support story. Not touched ----------- - sam_worker.py, dino_worker.py, sam_utils.py, dino_utils.py subprocess pattern (Phase 2, gated on Win+Py3.14 validation). - exec_() call sites outside main.py (still work as deprecated alias). https://claude.ai/code/session_01ADoBX5VmUYpCrwbkecKMHL --- .github/workflows/tests.yml | 4 +- CLAUDE.md | 10 +- README.md | 4 +- docs/02_architecture_constraints.md | 13 +- requirements.txt | 2 +- setup.py | 2 +- .../annotation_statistics.py | 6 +- .../annotation_utils.py | 22 +- .../annotator_window.py | 303 +++++++++--------- .../coco_json_combiner.py | 8 +- .../dataset_splitter.py | 6 +- .../dicom_converter.py | 14 +- .../dino_merge_dialog.py | 6 +- .../dino_phrase_editor.py | 14 +- .../dino_utils.py | 2 +- .../export_formats.py | 2 +- .../help_window.py | 4 +- .../image_augmenter.py | 10 +- .../image_label.py | 132 ++++---- .../image_patcher.py | 20 +- .../import_formats.py | 12 +- src/digitalsreeni_image_annotator/main.py | 11 +- .../project_details.py | 10 +- .../project_search.py | 6 +- .../sam_utils.py | 10 +- .../slice_registration.py | 16 +- .../snake_game.py | 23 +- .../stack_interpolator.py | 18 +- .../stack_to_slices.py | 12 +- .../yolo_trainer.py | 10 +- tests/conftest.py | 2 +- tests/integration/test_export_formats.py | 4 +- tests/unit/test_conversions.py | 4 +- tools/check_worker_isolation.py | 2 +- 34 files changed, 368 insertions(+), 356 deletions(-) diff --git a/.github/workflows/tests.yml b/.github/workflows/tests.yml index 69308a5..6712b97 100644 --- a/.github/workflows/tests.yml +++ b/.github/workflows/tests.yml @@ -27,7 +27,9 @@ jobs: if: runner.os == 'Linux' run: | sudo apt-get update - sudo apt-get install -y libxcb-xinerama0 libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-randr0 libxcb-render-util0 libxcb-shape0 libxcb-xfixes0 libxkbcommon-x11-0 libdbus-1-3 + # Qt6 Linux runtime: XCB plugin set + libEGL + xkbcommon. + # libxcb-cursor0 is REQUIRED for Qt6 (was optional in Qt5). + sudo apt-get install -y libxcb-xinerama0 libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-randr0 libxcb-render-util0 libxcb-shape0 libxcb-xfixes0 libxkbcommon-x11-0 libdbus-1-3 libegl1 libgl1 # For headless Qt testing sudo apt-get install -y xvfb x11-utils libxkbcommon-x11-0 libxcb-cursor0 diff --git a/CLAUDE.md b/CLAUDE.md index 2cfb7cb..f29bb04 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -2,7 +2,7 @@ This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. -DigitalSreeni Image Annotator - PyQt5 desktop app for image annotation with SAM 2 integration and multi-dimensional image support. +DigitalSreeni Image Annotator - PyQt6 desktop app for image annotation with SAM 2 integration and multi-dimensional image support. **Fork of**: https://github.com/bnsreenu/digitalsreeni-image-annotator @@ -20,9 +20,9 @@ python -m src.digitalsreeni_image_annotator.main ## Tech Stack -Python 3.10+ | PyQt5 5.15.11 | Ultralytics 8.3.27 (SAM 2) | NumPy | OpenCV | Shapely +Python 3.10+ | PyQt6 6.7+ | Ultralytics 8.3.27 (SAM 2) | NumPy | OpenCV | Shapely -**No automated tests exist** - all testing is manual. +**Test suite**: `tests/` (pytest + pytest-qt). 65 tests pass on PyQt6. ## Documentation @@ -99,8 +99,8 @@ prediction = self.sam_utils.apply_sam_points( ## Important Notes ### Platform Support -- ✅ Windows, macOS fully supported -- ⚠️ Linux has XCB issues, limited testing +- ✅ Windows, macOS, Linux supported (PyQt6 native integration improved over PyQt5) +- Linux runtime needs libxcb-cursor0 (Qt6 requires this; was optional under Qt5) ### Critical: Project Loading **Always check `is_loading_project` flag before saving!** Autosave during load corrupts files (v0.8.12 fix). diff --git a/README.md b/README.md index 5565eb0..104ab92 100644 --- a/README.md +++ b/README.md @@ -4,7 +4,7 @@ ![License](https://img.shields.io/badge/license-MIT-green) ![PyPI version](https://img.shields.io/pypi/v/digitalsreeni-image-annotator.svg?style=flat-square) -A powerful and user-friendly tool for annotating images with polygons and rectangles, built with PyQt5.

The DLL conflict that motivated the subprocess workers (ADR-011) no longer applies under PyQt6, so the ~1-2 s subprocess spawn per inference is gone, and models stay cached across calls. What changed ------------ - Deleted sam_worker.py (288 lines), dino_worker.py (231 lines), tools/check_worker_isolation.py (134 lines). - Rewrote sam_utils.py end-to-end: * SAMUtils inherits QObject, caches the Ultralytics model in self._model * change_sam_model() loads eagerly (on worker thread, UI stays alive) * apply_sam_points / apply_sam_prediction / apply_sam_predictions_batch all run inference on a QThread via the new _run_sync helper * Lazy import of torch/ultralytics keeps app startup snappy * Added unload() for future Tools-menu memory release - Rewrote dino_utils.py with the same pattern (DINOUtils as QObject, model cached across calls, transformers lazy-imported). - Added _run_sync: spawns a QThread, pumps the calling thread's QEventLoop until done. Public API stays synchronous so the existing call sites in annotator_window.py work unchanged. UI events (timers, redraws, progress dialog cancels) keep flowing during the wait. - Removed the stale "If you are on Python 3.14, PyTorch may not yet be fully supported" message in change_sam_model error path. - utils.py docstring: drop sam_worker reference. Docs ---- - ADR-011 marked Superseded, with pointer to ADR-013. - New ADR-013 documents the in-process + QThread decision, the latency win, and the trade-offs (re-entrancy via QEventLoop pump, no more crash isolation). - arc42 docs/05_building_block_view.md, docs/06_runtime_view.md, docs/12_glossary.md updated to drop subprocess wording. - CLAUDE.md SAM Integration section rewritten. Verification ------------ - 65 tests pass (pytest, QT_QPA_PLATFORM=offscreen). - Full app constructs and renders headlessly. - _run_sync round-trip verified end-to-end against a 0.3 s sleep. - Phase 0 PyQt6+torch+transformers+ultralytics coexistence smoke test passes on Linux+Py3.11.

Stores them on the thread instance; _run_sync re-raises on the calling thread. Silent model-load failures previously showed up as "No mask matches" / "No detections" dialogs with no way to diagnose. (sam_utils.py) - Added _inference_in_flight module flag + InferenceBusyError. The earlier QMutex draft would have deadlocked: same-thread re-acquisition of a non-recursive mutex hangs, and a recursive mutex would defeat the whole serialization point. A flag with an explicit exception surfaces re-entry instead of corrupting the model with concurrent .forward() calls. (sam_utils.py) - Added _sam_inference_in_flight guard in annotator_window.apply_sam_prediction — the SAM debounce timer can fire while a previous inference is pumping inside _run_sync; the guard skips the re-entrant call so the next click + debounce restart issues a fresh inference with the up-to-date point set. P1 — should-fix --------------- - dino_utils._detect_blocking no longer shuffles the model CPU<->GPU on every call. Moving a 1.9 GB DINO base over PCIe was wiping out the in-process caching gain the whole PR was meant to deliver. - change_sam_model now flips current_sam_model AFTER successful load, not before. On load failure the state stays consistent. - _qimage_to_numpy always returns a fresh copy. The fallback path was particularly broken: the converted QImage was local, would go out of scope at return, and the worker thread's numpy buffer would have aliased freed memory. - Updated misleading dino_utils.detect comment about marshaling — the safety actually comes from the .copy() inside _qimage_to_numpy, not from where it runs. - ADR-001 marked Superseded with pointer to new ADR-014. - New ADR-014 documents the PyQt5->PyQt6 migration decision. - Updated ADR-013 consequences to honestly describe the re-entrancy guards (replaced the "acceptable for now; revisit if users hit it" hand-wave the reviewer specifically called out). - docs/01_introduction_and_goals.md, docs/05_building_block_view.md (ASCII diagram), docs/06_runtime_view.md (app.exec_() typo) all updated for PyQt6. - CLAUDE.md: Testing Checklist no longer references deleted sam_worker /dino_worker; senior-reviewer agent prompt no longer references deleted check_worker_isolation.py. - .claude/agents/senior-reviewer.md retargeted from PyQt5 -> PyQt6 and rewritten to check ADR-013 re-entrancy guards instead of ADR-011's retired subprocess isolation. P2 — opportunistic ------------------ - tools/check_pyqt6_torch_coexistence.py now constructs a QApplication after importing torch. Pure import alone does not load Qt's native platform plugin (qwindows.dll on Windows) — which is the actual site of the historical WinError 1114. The previous green result was a false positive on the strictest test. - CI matrix gains Python 3.13. ADR-013 claims PyQt6+torch coexist on modern Pythons; this adds CI evidence (Py3.14 still manual via the coexistence script — pip wheels not yet broadly available). - CI apt-install list deduped (libxcb-cursor0 was listed twice). Verification ------------ - 65 tests pass. - Smoke-tested both fixes: exception propagation works (boom() raises ValueError out of _run_sync); re-entry detection works (timer-driven inner call raises InferenceBusyError while outer is pumping). - coexistence script with QApplication construction passes end-to-end on Linux+Py3.11. https://claude.ai/code/session_01ADoBX5VmUYpCrwbkecKMHL --- .claude/agents/senior-reviewer.md | 7 +- .github/workflows/tests.yml | 15 ++- CLAUDE.md | 4 +- docs/01_introduction_and_goals.md | 2 +- docs/05_building_block_view.md | 2 +- docs/06_runtime_view.md | 2 +- docs/09_architecture_decisions.md | 63 +++++++--- .../annotator_window.py | 110 ++++++++++------- .../dino_utils.py | 43 +++---- .../sam_utils.py | 116 +++++++++++++----- tools/check_pyqt6_torch_coexistence.py | 68 +++++++--- 11 files changed, 281 insertions(+), 151 deletions(-) diff --git a/.claude/agents/senior-reviewer.md b/.claude/agents/senior-reviewer.md index 2cb8486..58d047b 100644 --- a/.claude/agents/senior-reviewer.md +++ b/.claude/agents/senior-reviewer.md @@ -7,7 +7,7 @@ color: red You are a senior staff engineer with 20 years of experience.

The except block at the DINO call site (line 3022 pre-edit) referenced traceback.print_exc() without the module being importable in scope. Before the previous fix dino_utils.detect() returned None on error so the except was rarely entered; now it raises for real, so the NameError was about to start firing and leave the detect buttons permanently disabled with no user-visible dialog. P1 — should-fix --------------- - annotator_window.apply_sam_prediction now catches inference exceptions. The slot is driven by a QTimer; before this patch a CUDA OOM or InferenceBusyError would fall out into PyQt6's default unhandled-slot handler (stderr only). InferenceBusyError is suppressed silently (defense-in-depth alongside the call-site flag); other exceptions show a critical QMessageBox. - Same wrapping added to the unprotected SAM-batch calls inside both DINO flows (single image at line 3063, per-image loop at 3170). - Wired SAMUtils.unload() and DINOUtils.unload() to a new Tools menu entry "Unload AI Models (Free GPU Memory)". The DINO CPU<->GPU shuffle was removed in the previous round, which removes the automatic between-call free; this gives users on constrained GPUs a manual recovery path. - Bumped version 0.8.12 -> 0.9.0 in setup.py and __init__.py to signal the binding change (PyQt5 -> PyQt6) and the in-process inference rework. Anyone reading the wheel changelog now sees the binding switch in the version. - docs/05_building_block_view.md SAMUtils block rewritten to match the actual class shape (sam_model -> _model, qimage_to_numpy is a module-level helper not a method, _run_sync added). - Deleted PYTHON314_SETUP.md — it described the migration as future work, in the present tense, with the now-retired DLL workaround as a known issue. Easier to delete than keep coherent. P2 — cleanup ------------ - Dropped the unused `import traceback` in sam_utils.py (_InferenceThread captures exceptions on the instance now; no printing inside the worker). - The "No mask generated." batch fallback now builds a fresh dict per bbox via list comprehension instead of `[d] * N` (avoided shared-reference footgun). - Removed the dead `qimage_to_numpy` method on ImageAnnotator — module-level `_qimage_to_numpy` in sam_utils superseded it. - Folded the local `import traceback` inside `add_class`'s except block into the module-level import. Architectural belt-and-braces ----------------------------- - Added an assert at the top of `_run_sync`: the function MUST be called from the GUI thread. The `_inference_in_flight` flag is a plain global, not protected against cross-thread access — if a future contributor drives inference from a worker thread it becomes a true race. The assert is the tripwire. Reviewer flagged this as the kind of constraint that gets violated six months later when nobody remembers the design. Verification ------------ - 65 tests still pass. - Exception propagation and re-entry detection both re-tested in the full-app context — outer call returns 'done', timer-driven inner call raises InferenceBusyError, both as designed. - App constructs and renders headlessly. https://claude.ai/code/session_01ADoBX5VmUYpCrwbkecKMHL --- PYTHON314_SETUP.md | 239 ------------------ docs/05_building_block_view.md | 32 ++- setup.py | 2 +- src/digitalsreeni_image_annotator/__init__.py | 2 +- .../annotator_window.py | 123 ++++++--- .../sam_utils.py | 19 +- 6 files changed, 121 insertions(+), 296 deletions(-) delete mode 100644 PYTHON314_SETUP.md diff --git a/PYTHON314_SETUP.md b/PYTHON314_SETUP.md deleted file mode 100644 index 820c4d8..0000000 --- a/PYTHON314_SETUP.md +++ /dev/null @@ -1,239 +0,0 @@ -# Python 3.14 Setup Complete ✓ - -## Summary - -Successfully set up the testing infrastructure for the DigitalSreeni Image Annotator project with **Python 3.14.2** support. - -## What Was Fixed - -### 1.

Covers crashes, UX bugs, and silent failures that the 65-test pytest-qt suite doesn't exercise. PyQt5 → PyQt6 mechanical migration gaps: - 15× .exec_() → .exec() across annotator_window, dino_merge_dialog, image_patcher, project_search, snake_game, stack_to_slices. The QMenu crash on right-click in the class list (annotator_window:4607) was the first user-visible casualty. - Missing `import traceback` in dino_merge_dialog.py. - F2 (Snake game) moved from keyPressEvent to QShortcut(ApplicationShortcut) so QTableWidget's in-cell-edit doesn't swallow it. Canvas — pan + zoom-to-cursor: - Pan now uses event.globalPosition() so the widget shifting under the cursor mid-drag doesn't absorb half the delta (former half-speed pan). - New cursor-anchored Ctrl+wheel zoom; post-zoom offset derived analytically from viewport().width() instead of the stale self.width() that's wrong on zoom-out before layout settles. DINO panel + detection: - Threshold column widths (88 px fixed) + setFrame(True) so values "0,25" / "0,50" are readable. - PhraseEditorPanel auto-reveals on class-add; row-0 phrase is now renamable. Removed the silent class-name re-prepend in get_phrases_for + _run_for_class so a renamed row-0 actually reaches DINO. - Auto-accept dropdown now honored by both single + batch paths. - "Detect All Images" extended to multi-dim image slices via _collect_dino_batch_work_items (was silently skipping stacks). - New _navigate_to_image_or_slice handles slice names in batch review; orphan results are popped instead of leaving a half-state. - temp_annotations is a single field — _refresh_dino_temp_for_current syncs it on every switch_slice / switch_image so masks don't bleed between slices. - Application-wide _DINOReviewEventFilter makes Enter / Escape work during review regardless of which widget has focus. ADR-015 documents the choice over QShortcut and force-focus alternatives. - dino_batch_results initialised in __init__; dropped 4 lazy-hasattr checks. - Verbose [DINO] / [SAM] diagnostic prints at decision points (un-gated per user request — print is the project convention). Multi-dim TIFF loading: - load_tiff reads tifffile.series[0].axes and maps Y→H, X→W into the app's dimension vocab. DimensionDialog defaults to these hints when ndim matches. - Explicit ndim 3-6 fallback table, plus generic ["T"]*(ndim-2) + ["H","W"] for ndim ≥ 7. The earlier default_dimensions[-ndim:] of a 4-element list silently degraded for 5D TZCYX inputs and produced 2560 one-row "slices". Tools → Unload AI Models: - Three-step recipe: model.cpu() → gc.collect() → empty_cache + ipc_collect + synchronize. Disclosure dialog now mentions the per-process CUDA context that survives unload. - Resets both SAM + DINO dropdowns and disables Detect buttons on unload. YOLO export: - image_paths lookup uses exact-key match first, substring fallback only (prevents "bee.jpg" matching "honeybee.jpg" by substring). - Diagnostic [YOLO v5+] / [YOLO v4] prints, warning when a class isn't in class_mapping. Dark mode: - Dark mode now on by default at startup. - Removed hardcoded #e0e0e0 / #f5f5f5 from ClassThresholdTable header and lbl_dino_status (they punched bright boxes into the dark sidebar). - Added QRadioButton / QCheckBox / QHeaderView / QTableWidget / QSpinBox / QDoubleSpinBox / QComboBox / QGroupBox rules to soft_dark_stylesheet so dataset splitter radio buttons + DINO panel widgets render with adequate contrast. - Annotated-slice highlight changed from light blue (173,216,230) to muted steel-blue (58,95,140) on dark mode. Docs: - ADR-015 added — application-wide event filter for DINO review. - Cross-cutting concepts gained sections for Pan + Zoom Reference Frames, Dark Mode No Hardcoded Colors Rule, Releasing Model GPU Memory, DINO Temp Annotations (lifecycle / event filter / batch / navigation / auto-accept), Multi-dim TIFF Axis Defaults, Export Format Filename Matching. - CLAUDE.md gained a "Patterns introduced in v0.9.0" index table pointing at the arc42 deep-dives so new contributors don't re-derive them.
