Registers a 'Flag' object with a 'FlagValues' object.
tf.compat.v1.flags.DEFINE_flag(
flag, flag_values=_flagvalues.FLAGS, module_name=None
)
By default, the global FLAGS 'FlagValue' object is used.
Typical users will use one of the more specialized DEFINE_xxx functions, such as DEFINE_string or DEFINE_integer. But developers who need to create Flag objects themselves should use this function to register their flags.
flag: Flag, a flag that is key to the module.flag_values: 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.
