Object Storage Service:Upload vectors (Python SDK V2)

Permissions

Alibaba Cloud accounts have full permissions by default. RAM users and roles require explicit authorization through a RAM policy or a bucket policy.

Method definition

put_vectors(request: PutVectorsRequest, **kwargs) → PutVectorsResult

Request parameters

Return value

For the complete definition of the put_vectors method, see put_vectors.
