Function: set_dynamic_hw_size

C Prototype

aclError aclmdlSetDynamicHWSize(uint32_t modelId, aclmdlDataset *dataset, size_t index, uint64_t height, uint64_t width)

Python Function

ret = acl.mdl.set_dynamic_hw_size(model_id, dataset, index, height, width)

Function Usage

Sets the runtime image size for dynamic-shape model inference.

Input Description

model_id: int, model ID.

You can obtain the model ID after the model is successfully loaded by calling the following APIs:

dataset: input data of a model.

Data of type aclmdlDataset describes the input data for model inference, while data of type aclDataBuffer describes the input buffer size and address. For details, see aclmdlDataset.

index: int, index of the input dynamic batch, obtained by calling acl.mdl.get_input_index_by_name. For dynamic batch and image size, the input name is fixed to ascend_mbatch_shape_data. For dynamic AIPP, the input name is fixed to ascend_dynamic_aipp_data.

height: int, height to be set.

width: int, width to be set.

The configured image size (height and width) must be among the image size profiles set during model building. You can also call acl.mdl.get_dynamic_hw to obtain the number of image size profiles supported by a specified model and the width and height of each profile.

Return Value

ret: int, error code.

Restrictions

None
