check_numerics operations themselves are added for each half, float,
or double tensor in the current default graph. 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.
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.
eager compatibility
Not compatible with eager execution. To check for Infs and NaNs under
eager execution, call tf.debugging.enable_check_numerics() once before
executing the checked operations.
