class mindspore_lite.AscendDeviceInfo(device_id=0)[源代码]

用于设置Ascend设备信息的Helper类,继承自DeviceInfo基类。

参数:

  • device_id (int,可选) - 设备id。默认值:0。

异常:

  • TypeError - device_id 不是int类型。

  • ValueError - device_id 小于0。

样例:

>>> import mindspore_lite as mslite
>>> ascend_device_info = mslite.AscendDeviceInfo(device_id=0)
>>> print(ascend_device_info)
device_type: DeviceType.kAscend,
device_id: 0.
>>> cpu_device_info = mslite.CPUDeviceInfo(enable_fp16=False)
>>> context = mslite.Context()
>>> context.append_device_info(ascend_device_info)
>>> context.append_device_info(cpu_device_info)
>>> print(context)
