tf.debugging.assert_non_positive

Assert the condition x <= 0 holds element-wise.

tf.debugging.assert_non_positive(
    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 <= 0 everywhere, message, as well as the first summarize entries of x are printed, and InvalidArgumentError is raised.

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_non_positive".

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