insufficient shared memory (shm),怎么破？

ERROR: Unexpected BUS error encountered in DataLoader worker. This might be caused by insufficient shared memory (shm), please check whether use_shared_memory is set and storage space in /dev/shm is enough

  It may be caused by insufficient shared storage space. This problem usually occurs when using docker as a development environment.
  Please use command `df -h` to check the storage space of `/dev/shm`. Shared storage space needs to be greater than (DataLoader Num * DataLoader queue capacity * 1 batch data size).
  You can solve this problem by increasing the shared storage space or reducing the queue capacity appropriately.
