Object Storage Service:Get vector information (Python SDK V2)

Last Updated:Jun 03, 2026

You can call the GetVectors operation using the Python SDK V2 to retrieve vector data for specified keys. You can retrieve both the vector data and its metadata.

Permissions

Alibaba Cloud accounts have all permissions by default. By default, Resource Access Management (RAM) users or RAM roles under an Alibaba Cloud account do not have any permissions. The Alibaba Cloud account or an administrator must grant permissions for this operation using a RAM policy or a bucket policy.

Sample code

import argparse

import alibabacloud_oss_v2.vectors as oss_vectors

parser = argparse.ArgumentParser(description="vector get 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 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()

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

    vector_client = oss_vectors.Client(cfg)

    keys = ['key1', 'key2']

    result = vector_client.get_vectors(oss_vectors.models.GetVectorsRequest(
