isposinf

paddle. isposinf ( x: Tensor, name: str | None = None ) → Tensor [source]

Tests if each element of input is positive infinity or not.

Parameters

x (Tensor) – The input Tensor. Must be one of the following types: bfloat16, float16, float32, float64, int8, int16, int32, int64, uint8.
name (str|None, optional) – Name for the operation (optional, default is None). For more information, please refer to api_guide_Name.

Returns

out (Tensor), The output Tensor. Each element of output indicates whether the input element is positive infinity or not.

Examples

           >>> import paddle
>>> paddle.set_device('cpu')
>>> x = paddle.to_tensor([-0., float('inf'), -2.1, -float('inf'), 2.5], dtype='float32')
>>> res = paddle.isposinf(x)
>>> print(res)
Tensor(shape=[5], dtype=bool, place=Place(cpu), stop_gradient=True,
[False, True, False, False, False])
