描述

get_dl_device_paramget_dl_device_paramGetDlDeviceParamGetDlDeviceParamGetDlDeviceParamget_dl_device_param returns the parameter values GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value of GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name for the deep-learning-capable hardware device (hereafter referred to as device) DLDeviceHandleDLDeviceHandleDLDeviceHandleDLDeviceHandleDLDeviceHandledldevice_handle. See query_available_dl_devicesquery_available_dl_devicesQueryAvailableDlDevicesQueryAvailableDlDevicesQueryAvailableDlDevicesquery_available_dl_devices for details about deep-learning-capable hardware devices.

Supported values for GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name are:

'calibration_precisions'"calibration_precisions""calibration_precisions""calibration_precisions""calibration_precisions""calibration_precisions"：

Specifies the unit data types that can be used for a calibration of a deep learning model.

Possible values: 'int8'"int8""int8""int8""int8""int8".

'cast_precisions'"cast_precisions""cast_precisions""cast_precisions""cast_precisions""cast_precisions"：

Specifies the unit data types that can be used for a cast of a deep learning model.

When changing the data type the calibration does not require any images.

Possible values: 'float32'"float32""float32""float32""float32""float32", 'float16'"float16""float16""float16""float16""float16".

'conversion_supported'"conversion_supported""conversion_supported""conversion_supported""conversion_supported""conversion_supported"：

Returns 'true'"true""true""true""true""true" if unit data types for either a calibration or a cast of a deep learning model are available. Returns 'false'"false""false""false""false""false" in any other case.

'id'"id""id""id""id""id"：

The ID of the device. Within each inference engine, the IDs of its supported devices are unique. The same holds for devices supported through HALCON.

'inference_only'"inference_only""inference_only""inference_only""inference_only""inference_only"：

Indicates if the device can only be used to infer deep learning models ('true'"true""true""true""true""true") or also supports training or gradient-based operations ('false'"false""false""false""false""false").

'ai_accelerator_interface'"ai_accelerator_interface""ai_accelerator_interface""ai_accelerator_interface""ai_accelerator_interface""ai_accelerator_interface"：

AI Accelerator Interface (AI ²) on which this unit DLDeviceHandleDLDeviceHandleDLDeviceHandleDLDeviceHandleDLDeviceHandledldevice_handle is executed. In case the device is directly supported by HALCON, the value 'none'"none""none""none""none""none" is returned.

Possible values: 'tensorrt'"tensorrt""tensorrt""tensorrt""tensorrt""tensorrt", 'openvino'"openvino""openvino""openvino""openvino""openvino", 'none'"none""none""none""none""none".

'info'"info""info""info""info""info"：

Dictionary containing additional information on the device.

Restriction: Only for devices that are supported via an AI2-interface.

'name'"name""name""name""name""name"：

Name of the device.

'optimize_for_inference_params'"optimize_for_inference_params""optimize_for_inference_params""optimize_for_inference_params""optimize_for_inference_params""optimize_for_inference_params"：

Dictionary with default-defined conversion parameters for a calibration or cast operation of a deep learning model. The entries can be changed.

In case no parameter applies to the set device, an empty dictionary is returned.

Restriction: Only for devices that are supported via an AI2-interface.

'precisions'"precisions""precisions""precisions""precisions""precisions"：

Specifies the data types that the unit supports for the weights and/or activations of a deep-learning-based model.

Possible values: 'float32'"float32""float32""float32""float32""float32", 'float16'"float16""float16""float16""float16""float16", 'int8'"int8""int8""int8""int8""int8".

'settable_device_params'"settable_device_params""settable_device_params""settable_device_params""settable_device_params""settable_device_params"：

Dictionary with settable device parameters.

Restriction: Only for devices that are supported via an AI2-interface.

'type'"type""type""type""type""type"：

Type of the device.

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。
