PyTorch报错insufficient shared memory (shm)

报错

ERROR: Unexpected bus error encountered in worker. This might be caused by insufficient shared memory (shm)ERROR: Unexpected bus error encountered in worker. This might be caused by insufficient shared memory (shm)

解决方法

1、在服务器上的docker中运行训练代码时，batch size设置得过大，shared memory不够（因为docker限制了shm）.解决方法是，将Dataloader的num_workers设置为0.
