megengine.functional.logical_not

logical_not(x)

Element-wise logical NOT.

Computes the logical NOT for each element \(x_i\) of the input tensor \(x\).

Parameters

x – input tensor. Should have a boolean data type.

Returns

a tensor containing the result of the element-wise logical NOT operation. The returned tensor must have a data type of bool.

logical_and, logical_or, logical_xor

Examples

>>> F.logical_not(True)
Tensor(False, dtype=bool, device=xpux:0)

Element-wise logical NOT:

>>> x = Tensor([True, False, True])
>>> F.logical_not(x)
Tensor([False  True False], dtype=bool, device=xpux:0)

The ~ operator can be used as a shorthand for F.logical_and on boolean tensors.

>>> ~x
Tensor([False  True False], dtype=bool, device=xpux:0)
