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())`.T)rdevicetyper' RuntimeError device_count_fork_rng_warned_alreadyupperr(r)listrangerr zip) devicesenabled_caller _devices_kw device_type device_mod num_devicesr/ cpu_rng_stater5device_rng_statesdevice_rng_states r fork_rngrH}s'2f ,,{+00K T2J&{m3J K< =     --/ ?#;$$&''>{mL!!( *55@5F5F5H4IJ66A6G6G6I5JK((3(9(9(;'< @  MM' "'+ $u[)*w-'')MHOPf11&9PP?
