Docker Insufficient shared memory (shm) Error

When I running a training experiment in docker I got the following error message:

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

The solution is adding the argument “–ipc=host” when running the docker container.
