tf.compat.v1.flags.DEFINE_enum

Registers a flag whose value can be any string from enum_values.

tf.compat.v1.flags.DEFINE_enum(
    name,
    default,
    enum_values,
    help,
    flag_values=_flagvalues.FLAGS,
    module_name=None,
    required=False,
    **args
)

Instead of a string enum, prefer DEFINE_enum_class, which allows defining enums from an enum.Enum class.

name str, the flag name.
default str|None, the default value of the flag.
enum_values [str], a non-empty list of strings with the possible values for the flag.
help str, the help message.
flag_values :class:FlagValues, the FlagValues instance with which the flag will be registered. This should almost never need to be overridden.
module_name str, the name of the Python module declaring this flag. If not provided, it will be computed using the stack trace of this call.
required bool, is this a required flag. This must be used as a keyword argument.
**args dict, the extra keyword args that are passed to Flag.__init__.

a handle to defined flag.
