Object Storage Service:Buat indeks vektor (Python SDK V2)

Permissions

Akun Alibaba Cloud memiliki semua izin secara default. Pengguna RAM dan peran tidak memiliki izin secara default, sehingga harus diberikan akses melalui RAM policy atau bucket policy.

Method definition

put_vector_index(request: PutVectorIndexRequest, **kwargs) → PutVectorIndexResult

Untuk definisi lengkap metode ini, lihat put_vector_index.

Sample code

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

parser = argparse.ArgumentParser(description="vector put vector index 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 domain name that other services can use to access OSS')
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()

    # Muat kredensial dari variabel lingkungan
    credentials_provider = oss.credentials.EnvironmentVariableCredentialsProvider()

    # Menggunakan konfigurasi default SDK
    cfg = oss.config.load_default()
    cfg.credentials_provider = credentials_provider
    cfg.region = args.region
    cfg.account_id = args.account_id
    cfg.use_internal_endpoint = True  # Untuk mengakses layanan melalui jaringan publik, atur parameter ini ke False atau hapus baris ini.
    if args.endpoint is not None:
        cfg.endpoint = args.endpoint

    vector_client = oss_vectors.Client(cfg)

    result = vector_client.put_vector_index(oss_vectors.models.PutVectorIndexRequest(
        bucket=args.bucket,
        index_name=args.index_name,
        dimension=512,
        data_type='float32',
        distance_metric='euclidean',
        metadata={"nonFilterableMetadataKeys": ["key1", "key2"]}
    ))

    print(f'status code: {result.status_code},'
          f' request id: {result.request_id},'
    )

if __name__ == "__main__":
    main()
