Prototype

C Prototype

        
             aclError aclmdlGetDynamicHW(const aclmdlDesc *modelDesc, size_t index, aclmdlHW *hw)

Python Function

        
             hw_info, ret = acl.mdl.get_dynamic_hw(model_desc, index)

Parameters

Parameter	Description
model_desc	Int, pointer address of the data of the aclmdlDesc type. Call acl.mdl.create_desc to create data of the aclmdlDesc type in advance.
index	Int, reserved. The value is fixed to –1.

Parameter

Description

model_desc

Int, pointer address of the data of the aclmdlDesc type.

Call acl.mdl.create_desc to create data of the aclmdlDesc type in advance.

index

Int, reserved. The value is fixed to –1.

Returns

Return Value	Description
hw_info	Dict, width and height (image size) supported by the obtained model. The maximum number of HW profiles is 128. hw_info = { "hwCount": int,# Number of image size profiles supported by the model. "hw":[xx, xx,] # Specific image size profiles supported by the model. In each profile, the element whose index is 0 indicates the height, and the element whose index is 1 indicates the width. } If hwCount is 0, dynamic image size is not supported. The image size defined in the model applies.
ret	Int, error code. 0 indicates success. Other values indicate failure.

Return Value

Description

hw_info

Dict, width and height (image size) supported by the obtained model.

The maximum number of HW profiles is 128.

hw_info = {
"hwCount": int,# Number of image size profiles supported by the model.
"hw":[xx, xx,]  # Specific image size profiles supported by the model. In each profile, the element whose index is 0 indicates the height, and the element whose index is 1 indicates the width.
}

If hwCount is 0, dynamic image size is not supported. The image size defined in the model applies.

ret

Int, error code.

0 indicates success.
Other values indicate failure.
