class CFG:
    MODEL_ARCHITECTURE = 'convnext_large_in22k'  # State-of-the-art architecture
    IMAGE_SIZE = 512                              # High-resolution training
    BATCH_SIZE = 32                               # RTX 5090 optimized
    N_FOLDS = 5                                   # Cross-validation folds
    EPOCHS = 15                                   # Training epochs per fold
    NUM_WORKERS = 12                              # Multi-threading
    BASE_LR = 1e-3                               # Base learning rate

Troubleshooting

Memory Issues

# Reduce batch size for lower VRAM
CFG.BATCH_SIZE = 16  # or 8 for RTX 4090

# Reduce workers for system RAM constraints
CFG.NUM_WORKERS = 4

CUDA Compatibility

# Check CUDA installation
python -c "import torch; print(torch.cuda.is_available())"
python -c "import torch; print(torch.version.cuda)"

# Reinstall PyTorch with correct CUDA version
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121

Dependency Conflicts

The script includes automatic dependency resolution, but for manual fixes:

pip install --upgrade fastai timm torch

Advanced Features

Custom Model Integration

# Add custom models from TIMM
CFG.MODEL_ARCHITECTURE = 'efficientnetv2_xl_in21k'  # Alternative model
CFG.MODEL_ARCHITECTURE = 'swin_large_patch4_window12_384'  # Vision Transformer

Hyperparameter Optimization

# Learning rate scheduling
learn.fit_one_cycle(CFG.EPOCHS, lr_max=final_lr, div=25, pct_start=0.1)

# Custom augmentation strategy
def get_custom_transforms():
    return aug_transforms(
        size=CFG.IMAGE_SIZE,
