Ensures that only one flag among flag_names is not None.
tf.compat.v1.flags.mark_flags_as_mutual_exclusive(
flag_names, required=False, flag_values=_flagvalues.FLAGS
)
Important note: This validator checks if flag values are None
, and it does
not distinguish between default and explicit values. Therefore, this validator
does not make sense when applied to flags with default values other than None,
including other false values (e.g. False
, 0
, ''
, []
). That
includes multi flags with a default value of []
instead of None.
