mindspore.Tensor.allclose

Tensor.allclose(other, rtol=1e-05, atol=1e-08, equal_nan=False) → Tensor

Returns a new Tensor with boolean elements representing if each element of self is "close" to the corresponding element of other. Closeness is defined as:

$$|self-other|<=atol+rtolx|other|$$

Warning

This is an experimental API that is subject to change or deletion.

Parameters

• other (Tensor) – Tensor to compare. Dtype must be same as self.

• rtol (Union[float, int, bool], optional) – Relative tolerance. Default: 1e-05 .

• atol (Union[float, int, bool], optional) – Absolute tolerance. Default: 1e-08 .

• equal_nan (bool, optional) – If True , then two NaNs will be considered equal. Default: False.

Returns

A bool Scalar.

Raises

• TypeError – self or other is not Tensor.

• TypeError – Data types of self and other are not in the list of supported types.

• TypeError – atol or rtol is not float, int or bool.

• TypeError – equal_nan is not bool.

• TypeError – self and other have different dtypes.

• ValueError – self and other cannot broadcast.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor
>>> input = Tensor(np.array([1.3, 2.1, 3.2, 4.1, 5.1]), mindspore.float16)
>>> other = Tensor(np.array([1.3, 3.3, 2.3, 3.1, 5.1]), mindspore.float16)
>>> output = input.allclose(other)
>>> print(output)
False
