copyFrom

void copyFrom(const faiss::IndexIVFScalarQuantizer *index)

Copies AscendIndexIVFSQFuzzy to the Ascend based on an existing index and retains the resource configuration on the NPU of the original AscendIndex.

const faiss::IndexIVFSQ *index: index resources on the CPU.

The index must be a valid CPUindex pointer.

The member variables of the index must meet the following requirements:

• dim ∈ {64, 128, 256, 384, 512, 1024, 2048}
• nlist ∈ {1024, 2048, 4096, 8192, 16384, 32768}
• qtype = ScalarQuantizer::QuantizerType::QT_8bit (Currently, only ScalarQuantizer::QuantizerType::QT_8bit is supported.)
• metric = faiss::MetricType::METRIC_INNER_PRODUCT
