Returns the truth value of (x != y) element-wise.
tf.math.not_equal(
    x, y, name=None
)
Performs a broadcast with the
arguments and then an element-wise inequality comparison, returning a Tensor
of boolean values.
For example:
x = tf.constant([2, 4])
y = tf.constant(2)
tf.math.not_equal(x, y)
<tf.Tensor: shape=(2,), dtype=bool, numpy=array([False,  True])>
x = tf.constant([2, 4])
y = tf.constant([2, 4])
tf.math.not_equal(x, y)
<tf.Tensor: shape=(2,), dtype=bool, numpy=array([False,  False])>
Returns | 
A tf.Tensor of type bool with the same size as that of x or y.
