Function Usage

Loads and parses the AI CPU operator binary data from the memory, copies the data to the device corresponding to the current context, and outputs the binHandle that points to the data.

When calling this API to load an AI CPU operator (option_type in aclrtBinaryLoadOptions contains ACL_RT_BINARY_LOAD_OPT_CPU_KERNEL_MODE), call acl.rt.register_cpu_func to register the operator.

Python Function

bin_handle, ret = acl.rt.binary_load_from_data(mem_addr, length, options)

Parameter Description

Parameter	Description
mem_addr	Int, address of the host memory for storing the operator binary data. The value cannot be null.
length	Int, memory size of the operator binary data, in bytes. The value must be greater than 0.
options	List, optional options for loading the operator binary file. For details about the structure, see aclrtBinaryLoadOptions. If the options are empty, set options to [].

Return Value Description

Return Value	Description
bin_handle	Int, handle of the operator binary file.
ret	Int, 0 on success; else, failure.
