tf.debugging.assert_less

Assert the condition x < y holds element-wise.

tf.debugging.assert_less(     x, y, message=None, summarize=None, name=None )

This Op checks that x[i] < y[i] holds for every pair of (possibly broadcast) elements of x and y. If both x and y are empty, this is trivially satisfied.

If x < y does not hold, message, as well as the first summarize entries of x and y are printed, and InvalidArgumentError is raised.

When using inside tf.function, this API takes effects during execution. It's recommended to use this API with tf.control_dependencies to ensure the correct execution order.

In the following example, without tf.control_dependencies, errors may not be raised at all. Check tf.control_dependencies for more details.

def check_size(x):   with tf.control_dependencies([       tf.debugging.assert_less(tf.size(x), 3,                       message='Bad tensor size')]):     return x
 
check_size(tf.ones([2, 3], tf.float32)) Traceback (most recent call last):  InvalidArgumentError: ...

x Numeric Tensor.
y Numeric Tensor, same dtype as and broadcastable to x.
message A string to prefix to the default message. (optional)
summarize Print this many entries of each tensor. (optional)
name A name for this operation (optional). Defaults to "assert_less".

Op that raises InvalidArgumentError if x < y is False. This can be used with tf.control_dependencies inside of tf.functions to block followup computation until the check has executed.

InvalidArgumentError if the check can be performed immediately and x == y is False. The check can be performed immediately during eager execution or if x and y are statically known.
