how to process backend on multi-gpus?

[liangyongshi]

can the frontend and backend be processed respectively in two GPUS？

[liangyongshi]

I process the froentend in 5 GPUs ，and report errors：
ii, jj = torch.as_tensor(es, device=self.device).unbind(dim=-1)
ValueError: not enough values to unpack (expected 2, got 0)
how to process the backend in multi GPUS ？

Having same issue, anyone can help? Meanwhile, the current implementation actually runs global BA just before system termination, which is not real-time performance..
