logical_not

paddle. logical_not ( x, out=None, name=None ) [source]

logical_not operator computes element-wise logical NOT on x, and returns out. out is N-dim boolean Variable. Each element of out is calculated by

\[out = !x\]

Note

paddle.logical_not supports broadcasting. If you want know more about broadcasting, please refer to Introduction to Tensor .

Parameters

  • x (Tensor) – Operand of logical_not operator. Must be a Tensor of type bool, int8, int16, in32, in64, float16, float32, or float64.

  • out (Tensor) – The Tensor that specifies the output of the operator, which can be any Tensor that has been created in the program. The default value is None, and a new ``Tensor` will be created to save the output.

  • name (str|None) – The default value is None. Normally there is no need for users to set this property. For more information, please refer to Name.

Returns

N-D Tensor. A location into which the result is stored. It’s dimension equals with x.

Examples

import paddle

x = paddle.to_tensor([True, False, True, False])
res = paddle.logical_not(x)
print(res) # [False  True False  True]
