Delete vectors (Python SDK V2)

Permissions

An Alibaba Cloud account has all permissions by default. A Resource Access Management (RAM) user or RAM role has no permissions by default. The Alibaba Cloud account or an administrator must grant permissions using a RAM policy or a bucket policy.

Sample code

import argparse
import alibabacloud_oss_v2 as oss
import alibabacloud_oss_v2.vectors as oss_vectors

parser = argparse.ArgumentParser(description="vector delete vectors sample")
parser.add_argument('--region', help='The region in which the bucket is located.', required=True)
parser.add_argument('--bucket', help='The name of the bucket.', required=True)
parser.add_argument('--endpoint', help='The OSS access endpoint')
parser.add_argument('--index_name', help='The name of the vector index.', required=True)
parser.add_argument('--account_id', help='The account ID.', required=True)

def main():
    args = parser.parse_args()

    # Load credentials from environment variables
    credentials_provider = oss.credentials.EnvironmentVariableCredentialsProvider()

    # Using the SDK's default configuration
    cfg = oss.config.load_default()

    cfg.region = args.region
    cfg.account_id = args.account_id
    cfg.use_internal_endpoint = True  # Set to False or remove this line to access OSS over the public network.
    if args.endpoint is not None:
        cfg.endpoint = args.endpoint

    vector_client = oss_vectors.Client(cfg)

    keys = ['key1', 'key2', 'key3']

    result = vector_client.delete_vectors(oss_vectors.models.DeleteVectorsRequest(
        bucket=args.bucket,
        index_name=args.index_name,
        keys=keys,
    ))

    print(f'status code: {result.status_code},'
