有没有办法只在VisionLabelDetector中获得最高的置信度结果？

from google.cloud import vision

def detect_labels(path):
    """Detects labels in the file."""
    client = vision.ImageAnnotatorClient()

    with open(path, 'rb') as image_file:
        content = image_file.read()

    image = vision.Image(content=content)

    response = client.label_detection(image=image)
    labels = response.label_annotations

    # 设置参数获取最高置信度的结果
    response = client.label_detection(
        image=image,
        max_results=1
    )
    labels = response.label_annotations

    for label in labels:
        print(label.description, label.score)

detect_labels('path/to/image.jpg')
