用于删除所有未标记的图像的Boto3脚本

import boto3

def delete_unmarked_images(bucket_name):
    # 创建Rekognition客户端
    rekognition_client = boto3.client('rekognition')

    # 获取指定存储桶中的所有对象
    s3_client = boto3.client('s3')
    response = s3_client.list_objects_v2(Bucket=bucket_name)

    # 遍历所有对象
    for obj in response['Contents']:
        # 获取图像的标签
        response = rekognition_client.detect_labels(
            Image={'S3Object': {'Bucket': bucket_name, 'Name': obj['Key']}}
        )

        # 检查图像是否未标记
        if len(response['Labels']) == 0:
            # 删除未标记的图像
            s3_client.delete_object(Bucket=bucket_name, Key=obj['Key'])
            print(f"Deleted unmarked image: {obj['Key']}")

# 调用函数并传入存储桶名称
delete_unmarked_images('your-bucket-name')
