This solves the major issue of missing or incompatible configuration files that prevented users from using pre-trained models from the model zoo. The system includes automatic configuration generator for any FastReID model. ResNet depth detection and architecture mapping issues have been fixed. Support has been added for SBS, BOT, AGW, and MGN model types with proper fallbacks. A comprehensive model compatibility testing framework has been implemented. Error handling and validation for model loading have been enhanced. The generator creates both full and clean configuration files automatically. This fixes common issues including ResNet 101 models being misidentified as ResNet 34. YAML serialization errors with tuple parameters have been resolved. Missing configuration files for downloaded models are no longer an issue. Architecture detection from model filenames has been improved. The system now supports automatic detection and configuration generation for all model types in the FastReID model zoo.

Summary:
This PR introduces a detailed model zoo compatibility system that solves the major issue of missing or incompatible configuration files for pretrained models. Users can now automatically generate compatible configurations for any model from the FastReID model zoo.
Key Changes:
Automatic Configuration Generation:
The system includes an intelligent config generator for any FastReID model through generate_config.py. Enhanced detection of ResNet depths, IBN variants, and meta-architectures has been implemented. Automatic extraction of model parameters and architecture details is now available. The generator creates both full and clean configuration files.
Enhanced Model Support:
Full support has been added for all major FastReID architectures including SBS, BOT, AGW, and MGN. Proper detection of ResNet 18/34/50/101/152 variants is now implemented. IBN, SE, and Non-Local variant detection has been enhanced. Graceful handling of unsupported architectures provides proper fallback mechanisms.
Detailed Testing:
An automated testing framework for model compatibility has been implemented through test_model_compatibility.py. Built-in configuration validation and error checking provide a robust validation system. Proper cleanup and informative error messages ensure reliable error recovery.
Critical Bug Fixes:
ResNet 101 models being misidentified as ResNet 34 has been fixed. Tuple serialization issues in configurations have been resolved through improved YAML serialization. Filename based architecture detection has been improved. Better handling of different checkpoint formats provides enhanced checkpoint compatibility.
Problem Solved:
Before this change, users frequently encountered errors when trying to use pre-trained models such as KeyError: 'MODEL.BACKBONE.DEPTH', FileNotFoundError: config file not found, and TypeError: YAML serialization error with tuple.
After this change, users can automatically generate working configurations using python generate_config.py --model-path model.pth --save-path config.yml and then use python tools/test.py --config-file config_clean.yml --eval-only MODEL.WEIGHTS model.pth.
Benefits:
Testing:
The system has been tested with VeRiWild BOT R50-ibn models. Testing has been completed with Market-1501 SBS R101-ibn models. DukeMTMC AGW models have been validated. MSMT17 MGN models have been tested. Comprehensive error handling validation has been performed.
Usage Examples:
To generate config for any model, use python generate_config.py --model-path /path/to/model.pth --save-path model_config.yml. For testing with generated config, use python tools/test.py --config-file model_config_clean.yml --eval-only MODEL.WEIGHTS /path/to/model.pth. For demo usage, use python demo/demo.py --config-file model_config_clean.yml --input images/*.jpg --output results/.
This change eliminates one of the major issues for FastReID users and makes the model zoo truly accessible.
