-Multi-Series UI Bridge Converter
-
-This module provides a simplified bridge between the UI pipeline data and the 
-MultiSeriesDongleManager system, making it easy to convert UI configurations
-to working multi-series inference pipelines.
-
-Key Features:
-- Direct conversion from UI pipeline data to MultiSeriesDongleManager config
-- Simplified interface for deployment system
-- Automatic validation and configuration generation
-- Support for both folder-based and individual file configurations
-
-Usage:
-    from multi_series_converter import MultiSeriesConverter
-    
-    converter = MultiSeriesConverter()
-    manager = converter.create_multi_series_manager(pipeline_data, ui_config)
-    
-    manager.start()
-    sequence_id = manager.put_input(image, 'BGR565')
-    result = manager.get_result()

-Enhanced MFlow to Multi-Series API Converter
-
-This module extends the MFlowConverter to support multi-series dongle configurations
-by detecting multi-series model nodes and generating appropriate configurations for
-the MultiSeriesDongleManager.
-
-Key Features:
-- Detect multi-series enabled model nodes
-- Generate MultiSeriesStageConfig objects
-- Maintain backward compatibility with single-series configurations
-- Validate multi-series folder structures
-- Optimize pipeline for mixed single/multi-series stages
-
-Usage:
-    from multi_series_mflow_converter import MultiSeriesMFlowConverter
-    
-    converter = MultiSeriesMFlowConverter()
-    pipeline_config = converter.load_and_convert("pipeline.mflow")

-# Multi-Series Assets Folder Structure
-
-This folder contains firmware and models organized by dongle series for multi-series inference.
-
-## Structure:
-```
-Assets/
-├── Firmware/
-│   ├── KL520/
-│   │   ├── fw_scpu.bin
-│   │   └── fw_ncpu.bin
-│   ├── KL720/
-│   │   ├── fw_scpu.bin
-│   │   └── fw_ncpu.bin
-│   └── [other series...]
-└── Models/
-    ├── KL520/
-    │   └── [model.nef files]
-    ├── KL720/
-    │   └── [model.nef files]
-    └── [other series...]
-```
-
-## Usage:
-1. Place firmware files (fw_scpu.bin, fw_ncpu.bin) in the appropriate series subfolder under Firmware/
-2. Place model files (.nef) in the appropriate series subfolder under Models/
-3. Configure your model node to use this Assets folder in multi-series mode
-4. Select which series to enable in the model node properties
-
-## Supported Series:
-- **KL520**: Entry-level performance (3 GOPS)
-- **KL720**: Mid-range performance (28 GOPS)
-- **KL630**: High performance (400 GOPS)
-- **KL730**: Very high performance (1600 GOPS)
-- **KL540**: Specialized performance (800 GOPS)
-
-## Performance Benefits:
-The multi-series system automatically load balances inference across all enabled series
-based on their GOPS capacity for optimal performance. You can expect:
-
-- Higher overall throughput by utilizing multiple dongle types simultaneously
-- Automatic load balancing based on dongle capabilities
-- Seamless failover if one series becomes unavailable
-- Scalable performance as you add more dongles
-
-## Validation:
-Run `python utils/multi_series_setup.py validate --path <this_folder>` to validate your configuration.
-
-## Troubleshooting:
-- Ensure all firmware files are exactly named `fw_scpu.bin` and `fw_ncpu.bin`
-- Model files must have `.nef` extension
-- Each series must have both firmware and at least one model file
-- Check file permissions and accessibility

-Multi-Series Dongle Setup Help
-=============================
-
-This utility helps you set up and manage multi-series dongle configurations
-for improved inference performance.
-
-Commands:
----------
-
-create-structure --path <path> [--series KL520 KL720 ...]
-    Creates the recommended folder structure for multi-series assets.
-    
-    Example:
-        python utils/multi_series_setup.py create-structure --path "C:/MyAssets"
-        python utils/multi_series_setup.py create-structure --path "C:/MyAssets" --series 520 720
-
-validate --path <path>
-    Validates an existing assets folder structure.
-    
-    Example:
-        python utils/multi_series_setup.py validate --path "C:/MyAssets/Assets"
-
-list --path <path>
-    Lists all available series and their status in an assets folder.
-    
-    Example:
-        python utils/multi_series_setup.py list --path "C:/MyAssets/Assets"
-
-Setup Workflow:
---------------
-1. Create folder structure: create-structure --path "C:/MyProject"
-2. Copy firmware files to Assets/Firmware/KLxxx/ folders
-3. Copy model files to Assets/Models/KLxxx/ folders  
-4. Validate configuration: validate --path "C:/MyProject/Assets"
-5. Configure model node in UI to use Assets folder
-6. Enable multi-series mode and select desired series
-
-Performance Benefits:
--------------------
-- 2-5x throughput improvement with multiple series
-- Automatic load balancing based on dongle GOPS
-- Seamless scaling as you add more dongles
-- Fault tolerance if some dongles become unavailable
-
-Troubleshooting:
----------------
-- Ensure exact firmware file names: fw_scpu.bin, fw_ncpu.bin
-- Model files must have .nef extension
-- Check file permissions and paths
-- Verify dongle connectivity with single-series mode first
-- Use validate command to check configuration
-
-For more help, see Assets/README.md after creating the structure.
