mindspore.numpy.logical_not

mindspore.numpy.logical_not(a, dtype=None)[source]

Computes the truth value of NOT a element-wise.

Note

Numpy arguments out, where, casting, order, subok, signature, and extobj are not supported.

Parameters

  • a (Tensor) – The input tensor whose dtype is bool.

  • dtype (mindspore.dtype, optional) – Default: None. Overrides the dtype of the output Tensor.

Returns

Tensor or scalar. Boolean result with the same shape as a of the NOT operation on elements of a. This is a scalar if a is a scalar.

Raises

TypeError – if the input is not a tensor or its dtype is not bool.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore.numpy as np
>>> a = np.array([True, False])
>>> output = np.logical_not(a)
>>> print(output)
[False  True]
