mindspore.mint.isneginf

mindspore.mint.isneginf(input)[source]

Determines which elements are -inf for each position.

Warning

This is an experimental API that is subject to change.
This API can be used only on the Atlas A2 training series.

Parameters: input (Tensor) – Input Tensor.
Returns: Tensor with the same shape as the input, where elements are True if the corresponding element in the input is negative infinity, and False otherwise.
Raises: TypeError – If the input is not a tensor.

Supported Platforms:: Ascend

Examples

>>> from mindspore import mint, Tensor
>>> from mindspore import dtype as mstype
>>> output = mint.isneginf(Tensor([[-float("inf"), float("inf")], [1, -float("inf")]], mstype.float32))
>>> print(output)
[[ True False]
 [False  True]]
