AscendIndexInt8
API Definition |
AscendIndexInt8(int dims, faiss::MetricType metric, AscendIndexInt8Config config) |
|---|---|
Function |
Constructor of AscendIndexInt8, which is used to generate an AscendIndexInt8 whose dimension is dim. The NPU resources are configured based on the value configured in config. Note that the dimension of a group of vectors managed by a single index is unique. |
Input |
int dims: dimensions of a group of feature vectors managed by AscendIndexInt8. faiss::MetricType metric: distance measurement type used by AscendIndexInt8 when it retrieves feature vector similarity. Currently, faiss::MetricType::METRIC_L2 and faiss::MetricType::METRIC_INNER_PRODUCT are supported. AscendIndexInt8Config config: resource configuration on the NPU. |
Output |
N/A |
Return Value |
N/A |
Restrictions |
The value of dims is an integer ranging from 64 to 1024 and must be exactly divided by 64. |
