Function: get_mem_info

C Prototype	aclError *aclrtGetMemInfo(aclrtMemAttr attr, size_t free, size_t total)*
Python Function	free, total, ret = acl.rt.get_mem_info(attr)
Function Usage	Obtains the free and total memory sizes of a pyACL application with specified attributes, excluding the memory size reserved for the system.
Input Description	attr: int, memory attribute to be queried. For details, see aclrtMemAttr.
Return Value	free: int, free memory size of the corresponding attribute, in bytes. total: int, total memory size of the corresponding attribute, in bytes. ret: int, error code. 0 indicates success. Other values indicate failure.
Restrictions	Before calling this API, you must specify the compute device (for example, calling acl.rt.set_device to specify the compute device). Therefore, the device ID is not involved in this API. Atlas 200/300/500 Inference Product Select the memory of a specified attribute based on hardware. Otherwise, the free memory size and total memory size output by this API call are both 0. Atlas Training Series Product Select the memory of a specified attribute based on hardware. Otherwise, the free memory size and total memory size output by this API call are both 0.
