mindspore.mint.any

mindspore.mint.any(input, dim=None, keepdim=False)

检查指定维度上是否含有 True。

参数：

• input (Tensor) - 输入tensor。

• dim (Union[int, tuple(int), list(int), Tensor], 可选) - 要减少的维度。如果为 None，减少所有维度。默认 None 。

• keepdim (bool, 可选) - 输出tensor是否保留维度。默认 False 。

返回：

Tensor

支持平台：

Ascend

样例：

>>> import mindspore
>>> input = mindspore.tensor([[True, False], [True, True]])
>>>
>>> # case 1:  By default, mindspore.mint.any tests along all the axes.
>>> mindspore.mint.any(input)
Tensor(shape=[], dtype=Bool, value= True)
>>>
>>> # case 2: Reduces a dimension along dim 1, with keepdim False.
>>> mindspore.mint.any(input, dim=1)
Tensor(shape=[2], dtype=Bool, value= [ True,  True])
>>>
>>> # case 3: Reduces a dimension along dim (0, 1), with keepdim False.
>>> mindspore.mint.any(input, dim=(0,1))
Tensor(shape=[], dtype=Bool, value= True)
>>>
>>> # case 4: Reduces a dimension along dim [0, 1], with keepdim True.
>>> mindspore.mint.any(input, dim=[0,1], keepdim=True)
Tensor(shape=[1, 1], dtype=Bool, value=
[[ True]])
