dpnp.full_like

dpnp.full_like(a, /, fill_value, *, dtype=None, order='C', subok=False, shape=None, device=None, usm_type=None, sycl_queue=None)[source]

Return a full array with the same shape and type as a given array.

For full documentation refer to numpy.full_like.

Parameters:

  • a ({dpnp_array, usm_ndarray}) – The shape and dtype of a define these same attributes of the returned array.

  • fill_value ({scalar, array_like}) – Fill value, in any form that can be converted to an array. This includes scalars, lists, lists of tuples, tuples, tuples of tuples, tuples of lists, and ndarrays.

  • dtype (dtype, optional) – The desired dtype for the array, e.g., dpnp.int32. Default is the default floating point data type for the device where input array is allocated.

  • order ({"C", "F", None}, optional) – Memory layout of the newly output array. Default: “C”.

  • shape ({int, sequence of ints}) – Overrides the shape of the result.

  • device ({None, string, SyclDevice, SyclQueue}, optional) – An array API concept of device where the output array is created. The device can be None (the default), an OneAPI filter selector string, an instance of dpctl.SyclDevice corresponding to a non-partitioned SYCL device, an instance of dpctl.SyclQueue, or a Device object returned by dpnp.dpnp_array.dpnp_array.device property.

  • usm_type ({None, "device", "shared", "host"}, optional) – The type of SYCL USM allocation for the output array. Default is None.

  • sycl_queue ({None, SyclQueue}, optional) – A SYCL queue to use for output array allocation and copying.

Returns:

out – Array of fill_value with the same shape and type as a.

Return type:

dpnp.ndarray

Limitations

Parameter order is supported only with values "C", "F" and None. Parameter subok is supported only with default value False. Otherwise, the function raises NotImplementedError exception.

Examples

>>> import dpnp as np
>>> a = np.arange(6)
>>> np.full_like(a, 1)
array([1, 1, 1, 1, 1, 1])

Creating an array on a different device or with a specified usm_type

>>> x = np.full_like(a, 1) # default case
>>> x, x.device, x.usm_type
(array([1, 1, 1, 1, 1, 1]), Device(level_zero:gpu:0), 'device')

>>> y = np.full_like(a, 1, device="cpu")
>>> y, y.device, y.usm_type
(array([1, 1, 1, 1, 1, 1]), Device(opencl:cpu:0), 'device')

>>> z = np.full_like(a, 1, usm_type="host")
>>> z, z.device, z.usm_type
(array([1, 1, 1, 1, 1, 1]), Device(level_zero:gpu:0), 'host')
