How can make it run on multiple GPUs?\r\n\r\nI tried wrapping the frame_predictor, posterior and prior modules with `DataParallel`. Then I got the error, `No such attribute init_hidden for DataParallel`. So, I changed `frame_predictor.init_hidden()` to `frame_predictor.module.init_hidden()`. Then I got the error something like, `trying to do backward a second time. Graph not saved`.\r\n\r\nIs it possible to make the code run on multiple GPUs?"}}
