tf.debugging.assert_negative

View source

Assert the condition x < 0 holds element-wise.

Aliases:

  • tf.compat.v2.debugging.assert_negative
tf.debugging.assert_negative(
    x,
    message=None,
    summarize=None,
    name=None
)

This Op checks that x[i] < 0 holds for every element of x. If x is empty, this is trivially satisfied.

If x is not negative everywhere, message, as well as the first summarize entries of x are printed, and InvalidArgumentError is raised.

Args:

  • x: Numeric Tensor.
  • message: A string to prefix to the default message.
  • summarize: Print this many entries of each tensor.
  • name: A name for this operation (optional). Defaults to "assert_negative".

Returns:

Op raising InvalidArgumentError unless x is all negative. 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[i] < 0 is False. The check can be performed immediately during eager execution or if x is statically known.
