    Forks the RNG, so that when you return, the RNG is reset
    to the state that it was previously in.

    Args:
        devices (iterable of CUDA IDs): CUDA 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.
    r   Né   aô  CUDA reports that you have {num_devices} available devices, and you have used {caller} without explicitly specifying which devices are being used. For safety, we initialize *every* CUDA device by default, which can be quite slow if you have a lot of GPUs.  If you know that you are only making use of a few CUDA devices, set the environment variable CUDA_VISIBLE_DEVICES or the '{devices_kw}' keyword argument of {caller} with the set of devices you are actually using.  For example, if you are using CPU only, set CUDA_VISIBLE_DEVICES= or devices=[]; if you are using GPU 0 only, set CUDA_VISIBLE_DEVICES=0 or devices=[0].  To initialize all devices and suppress this warning, set the '{devices_kw}' keyword argument to `range(torch.cuda.device_count())`.)Únum_devicesZcallerZ
