Adds a constraint to multiple flags.
tf.compat.v1.flags.register_multi_flags_validator(
flag_names, multi_flags_checker, message='Flags validation failed',
flag_values=_flagvalues.FLAGS
)
The constraint is validated when flags are initially parsed, and after each change of the corresponding flag's value.
flag_names
: [str], a list of the flag names to be checked.multi_flags_checker
: callable, a function to validate the flag.
input - dict, with keys() being flag_names, and value for each key
being the value of the corresponding flag (string, boolean, etc).
output - bool, True if validator constraint is satisfied.
If constraint is not satisfied, it should either return False or
raise flags.ValidationError.message
: str, error text to be shown to the user if checker returns False.
If checker raises flags.ValidationError, message from the raised
error will be shown.flag_values
: flags.FlagValues, optional FlagValues instance to validate
against.AttributeError
: Raised when a flag is not registered as a valid flag name.
