Function Usage

Obtains model description from memory.

Prototype

C Prototype

        
             aclError aclmdlGetDescFromMem(aclmdlDesc *modelDesc, const void *model, size_t modelSize)

Python Function

        
             ret = acl.mdl.get_desc_from_mem(model_desc, model, model_size)

Parameters

Parameter	Description
model	Int, pointer address of the memory for storing model data. Allocate memory on the host or device based on where the application runs. For details about the memory allocation APIs, see Memory Management.
model_size	Int, size of the model data in the memory, in bytes.
model_desc	Int, pointer to data of the aclmdlDesc type. You need to call the create_desc API to create data of the aclmdlDesc type in advance. After the call is successful, the content in the pointer address is updated.

Parameter

Description

model

Int, pointer address of the memory for storing model data.

Allocate memory on the host or device based on where the application runs. For details about the memory allocation APIs, see Memory Management.

model_size

Int, size of the model data in the memory, in bytes.

model_desc

Int, pointer to data of the aclmdlDesc type. You need to call the create_desc API to create data of the aclmdlDesc type in advance. After the call is successful, the content in the pointer address is updated.

Returns

Return Value	Description
ret	Int, 0 on success; else, failure.

Restrictions

The model description obtained using this API cannot be used for the get_op_attr and get_cur_output_dims APIs.
