tensorflow.functions only supports singleton tensorflow.Variables. This means the variable will be created on the first
call of the tensorflow.function and will be reused across the subsequent calls. Creating a tensorflow.Variable that is not a
singleton will raise a ValueError.
import tensorflow as tf
@tf.function
def f(x):
v = tf.Variable(1.0)
return v
In the example above each time the function f will be called a new tensorflow.Variable will be created.
