For flags (e.g. ``--standalone``) use ``check_env`` instead. .. note:: when multiple option strings are specified, ``dest`` is the longest option string (e.g. for ``"-f", "--foo"`` the env var to set is ``PET_FOO`` not ``PET_F``) Example: :: parser.add_argument("-f", "--foo", action=env, default="bar") ./program -> args.foo="bar" ./program -f baz -> args.foo="baz" ./program --foo baz -> args.foo="baz" PET_FOO="env_bar" ./program -f baz -> args.foo="baz" PET_FOO="env_bar" ./program --foo baz -> args.foo="baz" PET_FOO="env_bar" ./program -> args.foo="env_bar" parser.add_argument("-f", "--foo", action=env, required=True) ./program -> fails ./program -f baz -> args.foo="baz" PET_FOO="env_bar" ./program -> args.foo="env_bar" PET_FOO="env_bar" ./program -f baz -> args.foo="baz" NFreturnc d|}tj||}|rd}t jd|||d|dS)NPET_F)destdefaultrequired)upperosenvirongetsuper__init__)selfr r r kwargsenv_name __class__s ]/var/www/html/CA-Chatbot/venv/lib/python3.11/site-packages/torch/distributed/argparse_util.pyrz env.__init__,sh($**,,((*..733  HQdGhQQ&QQQQQc2t||j|dSN)setattrr rparser namespacevalues option_strings r__call__z env.__call__9s 49f-----r)NFrNr__name__ __module__ __qualname____doc__rr! __classcell__rs@rrr sg< R R R R R R R........rrc.eZdZdZddfd Zd dZxZS) check_enva Check whether the env var ``PET_{dest}`` exists before defaulting to the given ``default`` value. Equivalent to ``store_true`` argparse built-in action except that the argument can be omitted from the commandline if the env var is present and has a non-zero value. .. note:: it is redundant to pass ``default=True`` for arguments that use this action because a flag should be ``True`` when present and ``False`` otherwise.
