> I write os.environ["CUDA_VISIBLE_DEVICES"]="1" before line 45,it works,I don't know it is right or wrong Hi, I wonder which .py file did you change ?

I modified 'os.environ["CUDA_VISIBLE_DEVICES"] = f"{MPI.COMM_WORLD.Get_rank() % GPUS_PER_NODE}"' in 'dist_util.py' at line 27 to 'os.environ["CUDA_VISIBLE_DEVICES"]="1"' in order to specify the GPU for training.
