Description

Loads and parses the operator binary file from a file and outputs the binHandle that points to the operator binary file.

For AI Core operators, if this API is used to load and parse the operator binary file, the acl.rt.launch_kernel_with_config API must be used to deliver the compute task.

Prototype

C Prototype

aclError aclrtBinaryLoadFromFile(const char* binPath, aclrtBinaryLoadOptions *options, aclrtBinHandle *binHandle)

Python Function

bin_handle, ret = acl.rt.binary_load_from_file(bin_path, options)

Parameters

Parameter	Description
bin_path	Str, path of the operator binary file (.o file). The path must be an absolute path. For AI CPU operators, this parameter can be set to an operator library file (.json).
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 Values

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

Restrictions

The operator binary file generated during the compilation of a product model must be used on the product of the same model.
