LoadGraph

int LoadGraph(const char *path, int level);

Loads a searcher from a specified path.

Parameter	Data Type	Description	Value Range
path	const char *	Path for loading the searcher.	The length must be less than 199 characters.
level	int	Quantization level.	[-1,3] -1: Default value, indicating the quantization level saved during the SaveGraph operation. 0: FP32 quantization. 1: SQ8U quantization. 2: SQ4U quantization. 3: FP16 quantization.
