Args: remote_device (str or torch.device): Represents a device on a remote worker. The string format should be one of the following: 1. "/", where the device field can be parsed as torch.device type. E.g., "trainer0/cpu", "trainer0", "ps0/cuda:0". In addition, the device field can be optional and the default value is "cpu". 2. "rank:/", where is the rank of the process and device can be parsed as torch.device type. E.g., "rank:0/cpu", "rank:0", "rank:0/cuda:0" 3. and are optional and formats like "cpu" and "cuda:1", just represent local devices. remote_devicecd|d}d|_d|_d|_t|tjr||_nt|t r|d}t|dkr|\|_|_nt|dkrCt |dr|d|_nC|d|_d|_n.t|tdt||j|jst|t j|j|_|j|jd }t|dkrX|dd kr=|dr#t|d|_d|_dSt|t|dkrt|dSdS) NzCould not parse remote_device: zU.
