tf.debugging.assert_non_negative

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

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.

xNumeric Tensor.
messageA string to prefix to the default message.
summarizePrint this many entries of each tensor.
nameA name for this operation (optional). Defaults to "assert_non_negative".

Op raising InvalidArgumentError unless x is all non-negative. This can be used with tf.control_dependencies inside of tf.functions to block followup computation until the check has executed.

InvalidArgumentErrorif 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.
