Tests element-wise for negative infinity.

Parameters: input (Tensor) – Input Tensor.
Returns: Tensor, true where input is negative infinity, false otherwise.
Raises: TypeError – If the input is not a tensor.

Supported Platforms:: Ascend GPU CPU

Examples

>>> output = ops.isneginf(Tensor([[-float("inf"), float("inf")], [1, -float("inf")]], mstype.float32))
>>> print(output)
[[ True False]
 [False  True]]
