cpu

cpu(device_id=0)

Returns a CPU context.

This function is a short cut for Context('cpu', device_id). For most operations, when no context is specified, the default context is cpu().

Parameters:

device_id : int, optional

The device id of the device. device_id is not needed for CPU. This is included to make interface compatible with GPU.

Returns:

context : Context

The corresponding CPU context.

Examples

>>> with mx.cpu():
...     cpu_array = mx.nd.ones((2, 3))
>>> cpu_array.context
cpu(0)
>>> cpu_array = mx.nd.ones((2, 3), ctx=mx.cpu())
>>> cpu_array.context
cpu(0)
