Args: devices (iterable of Device IDs): devices for which to fork the RNG. CPU RNG state is always forked. By default, :meth:`fork_rng` operates on all devices, but will emit a warning if your machine has a lot of devices, since this function will run very slowly in that case. If you explicitly specify devices, this warning will be suppressed enabled (bool): if ``False``, the RNG is not forked. This is a convenience argument for easily disabling the context manager without having to delete it and unindent your Python code under it. device_type (str): device type str, default is `cuda`. As for custom device, see details in [Note: support the custom device with privateuse1] metaNztorch has no module of `z`, you should register z,a module by `torch._register_device_module`.z reports that you have z& available devices, and you have used z_ without explicitly specifying which devices are being used. For safety, we initialize *every* zA device by default, which can be quite slow if you have a lot of z5s. If you know that you are only making use of a few z' devices, set the environment variable z_VISIBLE_DEVICES or the 'z' keyword argument of z with the set of devices you are actually using. For example, if you are using CPU only, set device.upper()_VISIBLE_DEVICES= or devices=[]; if you are using device 0 only, set zb_VISIBLE_DEVICES=0 or devices=[0]. To initialize all devices and suppress this warning, set the 'z#' keyword argument to `range(torch.z.device_count())`.Tc:g|]}|Sr)r).0device device_mods r zfork_rng..s'PPPf11&99PPPr )rr9typer' RuntimeError device_count_fork_rng_warned_alreadyupperr(r)listrangerr zip) r3enabled_caller _devices_kw device_type num_devicesr/ cpu_rng_statedevice_rng_statesr9device_rng_stater:s @r r2r2}s2f ,{++0K T22J K{ K K K< =      --// ??#;?$$&& @ @{ @ @!( @ @5@5F5F5H5H @ @7B6G6G6I6I @ @)4(9(9(;(; @ @ $$&& @ @ BM @ @ el @ @#((** @ @8C @ @!, @ @ @  M' " " "'+ $u[))**w--'))MPPPPPPP?
