For all ops in the graph, the `check_numerics` op for all of its (`half`, `float`, or `double`) inputs is guaranteed to run before the `check_numerics` op on any of its outputs. Note: This API is not compatible with the use of `tf.cond` or `tf.while_loop`, and will raise a `ValueError` if you attempt to call it in such a graph. Returns: A `group` op depending on all `check_numerics` ops added. Raises: ValueError: If the graph contains any numeric operations in a control flow structure. RuntimeError: If called with eager execution enabled. @compatibility(eager) Not compatible with eager execution.
