index_cpu_to_ascend

API definition	faiss::Index index_cpu_to_ascend(std::initializer_list<int> devices, const faiss::Index index, const AscendClonerOptions *options = nullptr);
Function	Copies and generates a retrieval index on the Ascend based on the retrieval index resources on the CPU.
Input	std::initializer_list<int> devices: device ID to be configured on the NPU. *const faiss::Index index: retrieval index resources on the CPU. const AscendClonerOptions options = nullptr*: AscendClonerOptions resources to be configured.
Output	N/A
Return value	Retrieval index generated on the Ascend.
Restrictions	After using the index, delete the pointer to destroy the corresponding space. The value of devices must be a valid and unique device ID. The maximum number of device IDs is 64. index must be a valid CPU Index pointer.
