--dynamic_image_size

Applicability

Description

Sets dynamic image size profiles. Applies to the scenario where the resolution of images input for inference is unfixed.

See Also

This option must be used in conjunction with --input_shape and is mutually exclusive with --dynamic_batch_size and --dynamic_dims.

Arguments

Argument: dynamic image size, for example, "imagesize1_height,imagesize1_width;imagesize2_height,imagesize2_width".

Format: Enclose the whole argument in double quotation marks (""), and separate the image sizes by commas (,).

Restrictions: The number of image size profiles has a value range (1, 100]. Separate each image size by a semicolon (;).

Suggestions and Benefits

• Too large image sizes or too many image size profiles will cause model tuning failures.
• In the scenario where you have set too large image sizes or too many image size profiles, you are advised to run the swapoff -a command to disable the use of swap space as memory to prevent slow operating environment.

Examples

--input_shape="data:8,3,-1,-1;img_info:8,4,-1,-1"  --dynamic_image_size="416,416;832,832"

Where, -1 in --input_shape indicates dynamic image size enabled. When the AOE tunes a model, the supported input combinations are as follows:

Profile 0: data(8,3,416,416)+img_info(8,4,416,416)

Profile 1: data(8,3,832,832)+img_info(8,4,832,832)

Dependencies and Restrictions

• Restrictions:

  If dynamic image size is enabled, the sizes of the dataset images used for inference must match the runtime image size in use.

• API Restrictions:

  If this option is used to set dynamic image size during model tuning, the aclmdlSetDynamicHWSize API should be called before aclmdlExecute to set the runtime image size.

  For details about how to use the aclmdlSetDynamicHWSize API, see ""Model Execution"".
