LoadGraph

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

Load a searcher from a specified path.

Parameter	Description	Data Type	Value Range
path	Path for loading the searcher.	const char *	The length must be less than 199 characters.
level	Quantization level.	int	[-1,5] -1: Default value, indicating the quantization level saved during the SaveGraph operation. 0: FP32 quantization. 1: SQ8U quantization. 2: SQ4U quantization. 3: FP16 quantization. 4: SQ8 quantization. 5: SQ4 quantization.
