mindspore_lite.AscendDeviceInfo

class mindspore_lite.AscendDeviceInfo(device_id=0)[source]

Helper class used to describe Ascend device hardware information, and it inherits mindspore_lite.DeviceInfo base class.

Parameters

device_id (int, optional) – The device id. Default: 0.

Raises

TypeError – device_id is not an int.
ValueError – device_id is less than 0.

Examples

>>> # Use case: inference on Ascend device.
>>> # precondiction 1: Building MindSpore Lite Ascend package on Ascend device.
>>> # precondiction 2: install wheel package of MindSpore Lite built by precondiction 1.
>>> import mindspore_lite as mslite
>>> ascend_device_info = mslite.AscendDeviceInfo(device_id=0)
>>> print(ascend_device_info)
