# Create sample dataset with 50 images per class
create_sample_dataset("data", num_samples=50)

Data Validation

Validate your dataset before training:

from src.utils import validate_data_directory

is_valid, message = validate_data_directory("data")
if is_valid:
    print("✓ Dataset is valid")
else:
    print(f"✗ Dataset issues: {message}")

# Build and train model
classifier.build_model()
classifier.train(train_dataset, val_dataset, epochs=20)

# Evaluate model
