Tf1 Compatibility
When in TF V1 mode (that is, outside tf.function) Assert needs a control
dependency on the output to ensure the assertion executes:
# Ensure maximum element of x is smaller or equal to 1
assert_op = tf.Assert(tf.less_equal(tf.reduce_max(x), 1.), [x])
with tf.control_dependencies([assert_op]):
... code using x ...
Eager Compatibility
returns None
