mindspore.ops.ones_like

mindspore.ops.ones_like(input, *, dtype=None)[source]

Returns a Tensor with a value of 1 and its shape is the same as the input.

Parameters: input (Tensor) – Tensor of any dimension.
Keyword Arguments: dtype (mindspore.dtype, optional) – The specified dtype of the output tensor. If dtype is None , the dtype of the input tensor will be used. Default: None .
Returns: Tensor, has the same shape as input but filled with ones.
Raises: TypeError – If input is not a Tensor.

Supported Platforms:: Ascend GPU CPU

Examples

>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> x = Tensor(np.array([[0, 1], [2, 1]]).astype(np.int32))
>>> output = ops.ones_like(x)
>>> print(output)
[[1 1]
 [1 1]]
