tf.compat.v1.keras.backend.variable

tf.keras.backend.variable(
    value, dtype=None, name=None, constraint=None
)

Arguments
value	Numpy array, initial value of the tensor.
dtype	Tensor type.
name	Optional name string for the tensor.
constraint	Optional projection function to be applied to the variable after an optimizer update.

Returns
A variable instance (with Keras metadata included).

Examples:

val = np.array([[1, 2], [3, 4]])
kvar = tf.keras.backend.variable(value=val, dtype='float64',
                                 name='example_var')
tf.keras.backend.dtype(kvar)
'float64'
print(kvar)
<tf.Variable 'example_var:...' shape=(2, 2) dtype=float64, numpy=
  array([[1., 2.],
         [3., 4.]])>
