mindspore.ops.ones

mindspore.ops.ones(shape, dtype=None)[source]

Creates a tensor filled with value ones.

Warning

Non-backward-compatible change after version 2.9.0: shape will be renamed to size, and dtype will become keyword-only. Tensor type input for shape is deprecated in the current version.

Parameters

shape (Union[tuple[int], list[int], int, Tensor]) – The shape specified.
dtype (mindspore.dtype) – The data type specified. Default None .

Returns

Tensor

Supported Platforms:: Ascend GPU CPU

Examples

>>> import mindspore
>>> mindspore.ops.ones(4)
Tensor(shape=[4], dtype=Float32, value= [ 1.00000000e+00,  1.00000000e+00,  1.00000000e+00,  1.00000000e+00])
>>> mindspore.ops.ones((2, 3))
Tensor(shape=[2, 3], dtype=Float32, value=
[[ 1.00000000e+00,  1.00000000e+00,  1.00000000e+00],
 [ 1.00000000e+00,  1.00000000e+00,  1.00000000e+00]])
>>> mindspore.ops.ones(mindspore.tensor([1, 2, 3]))
Tensor(shape=[1, 2, 3], dtype=Float32, value=
[[[ 1.00000000e+00,  1.00000000e+00,  1.00000000e+00],
  [ 1.00000000e+00,  1.00000000e+00,  1.00000000e+00]]])
