Function: repo_add

Description

Adds a repository, or adds features to an existing repository. In this section, 1:N indicates the number of search requests divided by the number of base libraries. N:M is used to compare the similarity between two libraries.

The Atlas inference accelerator module of the Atlas inference product does not support this API.

Prototype

C Prototype

        
             aclError aclfvRepoAdd(aclfvSearchType type, aclfvFeatureInfo *featureInfo)

Python Function

        
             ret = acl.fv.repo_add(type, feature_info)

Parameters

Parameter	Description
type	Search type. The value is of the int type. For details, see aclfvSearchType.
feature_info	Int, address of the pointer that points to feature description. Call acl.fv.create_feature_info to create data of the aclfvFeatureInfo type in advance.

Return Value

Return Value	Description
ret	Int, error code. 0 indicates success. Other values indicate failure.

Restrictions

In 1:N mode, ensure that the offsets in the aclfvFeatureInfo dictionary are consecutive for each repository. In N:M mode, if the offset is not 0, an error is reported.
In N:M mode, multithreaded adding, search, or deletion is not allowed.
This API call automatically creates a stream for synchronous task execution within the API. When the tasks are complete, the stream is automatically destroyed.
Due to hardware restrictions, the total number of streams is limited. For details, see the description of Function: create_stream.
