import pandas as pd

# Download and load the model
model_path = hf_hub_download(
    repo_id="ThabangTheActuaryCoder/insurance-fraud-detection-model",
    filename="fraud_detection_model.joblib",
)
model = joblib.load(model_path)

# Create a sample input
sample = pd.DataFrame([{"claim_amount": 0, "policy_tenure_months": 0, "customer_age": 0, "num_prior_claims": 0, "premium_amount": 0, "days_to_report": 0, "witness_present": 0, "police_report_filed": 0, "vehicle_age_years": 0, "incident_type": 0, "province": 0}])

# Predict
prediction = model.predict(sample)
probabilities = model.predict_proba(sample)
print(f"Prediction: {prediction}, Probabilities: {probabilities}")
