tf.debugging.assert_non_negative(
    x, data=None, summarize=None, message=None, name=None
)

When running in graph mode, you should add a dependency on this operation to ensure that it runs. Example of adding a dependency to an operation:

with tf.control_dependencies([tf.debugging.assert_non_negative(x, y)]):
  output = tf.reduce_sum(x)

Non-negative means, for every element x[i] of x, we have x[i] >= 0. If x is empty this is trivially satisfied.

Args
x	Numeric Tensor.
data	The tensors to print out if the condition is False. Defaults to error message and first few entries of 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_non_negative".

Returns
Op that raises InvalidArgumentError if x >= 0 is False.

Raises
InvalidArgumentError	if the check can be performed immediately and x >= 0 is False. The check can be performed immediately during eager execution or if x is statically known.
