[Ask]multiple gpu

[UdonDa]

Hi NVlabs. Please tell me! When I want to use multiple GPUs with this code, how should I do?

I also meet this problem. It only uses one GPU. I also want to use multiple GPU to accelerate the training progress. ^_^

@thinkerthinker It makes RuntimeError... what should i do?

RuntimeError: DataLoader worker (pid 40228) is killed by signal: Bus error. Details are lost due to multiprocessing. Rerunning with num_workers=0 may give better error trace.

@thinkerthinker Even if we add "CUDA_VISIBLE_DEVICES=x,x,x" before the script it still uses one GPU.
