mindspore.Tensor.isneginf

Tensor.isneginf() → Tensor

Determines which elements are -inf for each position.

Warning

  • This is an experimental API that is subject to change.

  • For Ascend, it is only supported on platforms above Atlas A2.

Returns

Tensor with the same shape as the self, where elements are True if the corresponding element in the self is negative infinity, and False otherwise.

Supported Platforms:

Ascend GPU CPU

Examples

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