I have the following two questions

I cannot set the num_workers in Dataloader to any number grater then 0. it will have an error like . what’s the problem?

RuntimeError: DataLoader worker (pid 28830) is killed by signal: Bus error. Details are lost due to multiprocessing. Rerunning with num_workers=0 may give better error trace


when num_workers = 0,  the cpu(6 cores, 12 threads) seems to be running with multiple threads… why?
