jax.numpy.not_equal(x1, x2)

Return (x1 != x2) element-wise.

LAX-backend implementation of not_equal(). Original docstring below.

not_equal(x1, x2, /, out=None, *, where=True, casting=’same_kind’, order=’K’, dtype=None, subok=True[, signature, extobj])


x2 (x1,) – Input arrays. If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).


out – Output array, element-wise comparison of x1 and x2. Typically of type bool, unless dtype=object is passed. This is a scalar if both x1 and x2 are scalars.

Return type

ndarray or scalar


>>> np.not_equal([1.,2.], [1., 3.])
array([False,  True])
>>> np.not_equal([1, 2], [[1, 3],[1, 4]])
array([[False,  True],
       [False,  True]])
