Hi guys! but will be deprecated eventually. I think it should be similar as running usual pytorch multi-node applications: , where you need to specify other arguments like HOST_NODE_ADDR. The error mentions THD, which implies youre using an older version of PyTorch. T, the reference target, A, alignment info, E the history of generation steps.
