mindspore.ops.Eye

class mindspore.ops.Eye(*args, **kwargs)[source]

Creates a tensor with ones on the diagonal and zeros the rest.

Inputs:

n (int) - The number of rows of returned tensor. only constant value.
m (int) - The number of columns of returned tensor. only constant value.
t (mindspore.dtype) - MindSpore’s dtype, The data type of the returned tensor. The data type can be Number.

Outputs:

Tensor, a tensor with ones on the diagonal and the rest of elements are zero. The shape of output depends on the user’s Inputs n and m. And the data type depends on Inputs t.

Raises

TypeError – If m or n is not an int.
ValueError – If m or n is less than 1.

Supported Platforms:: Ascend GPU CPU

Examples

>>> eye = ops.Eye()
>>> output = eye(2, 2, mindspore.int32)
>>> print(output)
[[1 0]
 [0 1]]
>>> print(output.dtype)
Int32
>>> output = eye(1, 2, mindspore.float64)
>>> print(output)
[[1. 0.]]
>>> print(output.dtype)
Float64
>>> # if wants a anti-diagonal
>>> anti_diagonal_input = eye(2, 2, mindspore.int32)
>>> # Note that ReverseV2 only supports "Ascend" at this time
>>> reverse = ops.ReverseV2([1])
>>> anti_diagonal_output = reverse(anti_diagonal_input)
>>> print(anti_diagonal_output)
[[0 1]
 [1 0]]
