Assert the condition x != y holds for all elements.

tf.compat.v2.debugging.assert_none_equal(
    x,
    y,
    summarize=None,
    message=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 any elements of x and y are equal, message, as well as the first summarize entries of x and y are printed, and InvalidArgumentError is raised.

Args:

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

Returns:

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

Raises:

  • InvalidArgumentError: if the check can be performed immediately and x != y is False for any pair of elements in x and y. The check can be performed immediately during eager execution or if x and y are statically known.
