tf.compat.v1.app.flags.mark_flag_as_required

tf.compat.v1.flags.mark_flag_as_required(
    flag_name, flag_values=_flagvalues.FLAGS
)

Registers a flag validator, which will follow usual validator rules. Important note: validator will pass for any non-None value, such as False, 0 (zero), '' (empty string) and so on.

If your module might be imported by others, and you only wish to make the flag required when the module is directly executed, call this method like this:

if name == 'main': flags.mark_flag_as_required('your_flag_name') app.run()

Args
flag_name	str, name of the flag
flag_values	flags.FlagValues, optional FlagValues instance where the flag is defined.

Raises
AttributeError	Raised when flag_name is not registered as a valid flag name.
