From 8ce40a938514c79ecd930b6c5c3d380b321ae219 Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Tue, 31 Mar 2026 05:49:51 +0300 Subject: [PATCH] Add AIAvailabilityStatus and AIRecognitionConfig classes for AI model management - Introduced `AIAvailabilityStatus` class to manage the availability status of AI models, including methods for setting status and logging messages. - Added `AIRecognitionConfig` class to encapsulate configuration parameters for AI recognition, with a static method for creating instances from dictionaries. - Implemented enums for AI availability states to enhance clarity and maintainability. - Updated related Cython files to support the new classes and ensure proper type handling. These changes aim to improve the structure and functionality of the AI model management system, facilitating better status tracking and configuration handling. --- .../skills/refactor/phases/01-discovery.md | 46 +++- .gitignore | 3 + Dockerfile | 1 + Dockerfile.gpu | 1 + _docs/02_document/architecture.md | 1 - ...172_distributed_architecture_adaptation.md | 107 ++++++++ .../backlog/AZ-173_stream_based_run_detect.md | 65 +++++ .../backlog/AZ-174_db_driven_ai_config.md | 76 ++++++ .../backlog/AZ-175_media_table_integration.md | 73 +++++ .../AZ-176_cleanup_obsolete_path_code.md | 65 +++++ .../01-code-cleanup/baseline_metrics.md | 52 ++++ .../discovery/logical_flow_analysis.md | 193 +++++++++++++ .../01-code-cleanup/list-of-changes.md | 132 +++++++++ _docs/_autopilot_state.md | 20 +- constants_inf.h | 55 ---- e2e/run_local.sh | 1 + engines/__init__.pxd | 0 engines/inference_engine.pxd | 10 - engines/inference_engine.pyx | 25 -- requirements.txt | 1 - run-tests.sh | 8 +- setup.py | 26 +- .../ai_availability_status.pxd | 3 +- .../ai_availability_status.pyx | 10 +- ai_config.pxd => src/ai_config.pxd | 4 - ai_config.pyx => src/ai_config.pyx | 35 +-- annotation.pxd => src/annotation.pxd | 3 - annotation.pyx => src/annotation.pyx | 23 -- constants_inf.pxd => src/constants_inf.pxd | 9 +- constants_inf.pyx => src/constants_inf.pyx | 12 +- {engines => src/engines}/__init__.py | 0 {engines => src/engines}/coreml_engine.pxd | 3 +- {engines => src/engines}/coreml_engine.pyx | 59 ++-- src/engines/inference_engine.pxd | 12 + src/engines/inference_engine.pyx | 106 ++++++++ {engines => src/engines}/onnx_engine.pxd | 1 - {engines => src/engines}/onnx_engine.pyx | 16 +- {engines => src/engines}/tensorrt_engine.pxd | 6 +- {engines => src/engines}/tensorrt_engine.pyx | 95 ++++--- inference.pyx => src/inference.pyx | 254 ++++++------------ .../loader_http_client.pxd | 1 - .../loader_http_client.pyx | 7 +- main.py => src/main.py | 32 ++- 43 files changed, 1190 insertions(+), 462 deletions(-) create mode 100644 _docs/02_tasks/backlog/AZ-172_distributed_architecture_adaptation.md create mode 100644 _docs/02_tasks/backlog/AZ-173_stream_based_run_detect.md create mode 100644 _docs/02_tasks/backlog/AZ-174_db_driven_ai_config.md create mode 100644 _docs/02_tasks/backlog/AZ-175_media_table_integration.md create mode 100644 _docs/02_tasks/backlog/AZ-176_cleanup_obsolete_path_code.md create mode 100644 _docs/04_refactoring/01-code-cleanup/baseline_metrics.md create mode 100644 _docs/04_refactoring/01-code-cleanup/discovery/logical_flow_analysis.md create mode 100644 _docs/04_refactoring/01-code-cleanup/list-of-changes.md delete mode 100644 constants_inf.h delete mode 100644 engines/__init__.pxd delete mode 100644 engines/inference_engine.pxd delete mode 100644 engines/inference_engine.pyx rename ai_availability_status.pxd => src/ai_availability_status.pxd (76%) rename ai_availability_status.pyx => src/ai_availability_status.pyx (83%) rename ai_config.pxd => src/ai_config.pxd (88%) rename ai_config.pyx => src/ai_config.pyx (76%) rename annotation.pxd => src/annotation.pxd (83%) rename annotation.pyx => src/annotation.pyx (72%) rename constants_inf.pxd => src/constants_inf.pxd (61%) rename constants_inf.pyx => src/constants_inf.pyx (88%) rename {engines => src/engines}/__init__.py (100%) rename {engines => src/engines}/coreml_engine.pxd (70%) rename {engines => src/engines}/coreml_engine.pyx (54%) create mode 100644 src/engines/inference_engine.pxd create mode 100644 src/engines/inference_engine.pyx rename {engines => src/engines}/onnx_engine.pxd (90%) rename {engines => src/engines}/onnx_engine.pyx (82%) rename {engines => src/engines}/tensorrt_engine.pxd (85%) rename {engines => src/engines}/tensorrt_engine.pyx (62%) rename inference.pyx => src/inference.pyx (64%) rename loader_http_client.pxd => src/loader_http_client.pxd (93%) rename loader_http_client.pyx => src/loader_http_client.pyx (93%) rename main.py => src/main.py (91%) diff --git a/.cursor/skills/refactor/phases/01-discovery.md b/.cursor/skills/refactor/phases/01-discovery.md index 5621bac..8617577 100644 --- a/.cursor/skills/refactor/phases/01-discovery.md +++ b/.cursor/skills/refactor/phases/01-discovery.md @@ -37,7 +37,13 @@ For each file/area referenced in the input file: Write per-component to `RUN_DIR/discovery/components/[##]_[name].md` (same format as automatic mode, but scoped to affected areas only). -### 1i.

Source moved to src/. InferenceEngine base class now owns preprocess/postprocess/process_frames with per-engine max_batch_size. CoreML overrides preprocess (direct PIL, no blob reversal) and postprocess. TensorRT calculates max_batch_size from GPU memory (80% fraction) with optimization profiles for dynamic batch. All logical flow bugs fixed (LF-01 through LF-09). Dead code removed (msgpack, serialize, unused constants). POST /detect unified through run_detect. Next: Step 8 (architecture shift — streaming media, DB-backed config, media storage, Jetson support). ## Blockers - none diff --git a/constants_inf.h b/constants_inf.h deleted file mode 100644 index 620b985..0000000 --- a/constants_inf.h +++ /dev/null @@ -1,55 +0,0 @@ -/* Generated by Cython 3.1.2 */ - -#ifndef __PYX_HAVE__constants_inf -#define __PYX_HAVE__constants_inf - -#include "Python.h" - -#ifndef __PYX_HAVE_API__constants_inf - -#ifdef CYTHON_EXTERN_C - #undef __PYX_EXTERN_C - #define __PYX_EXTERN_C CYTHON_EXTERN_C -#elif defined(__PYX_EXTERN_C) - #ifdef _MSC_VER - #pragma message ("Please do not define the '__PYX_EXTERN_C' macro externally.
