# > Note: This sort of error will happen when the uid/gid does not exist in the /etc/passwd or /etc/group 
#         file inside the container. There are various ways to work around that. 
#         One is to directly map these files from your host into the container with something like:
#         "-v /etc/passwd:/etc/passwd:ro -v /etc/group:/etc/group:ro"

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

# "--num-workers 0" will slow down training.
# I fixed it by adding "--ipc=host" in my docker container configuration.

# NOTE: docker run :
# --rm: Automatically remove the container when it exits;
# --tty , -t		Allocate a pseudo-TTY;
# --volume , -v		Bind mount a volume;
# --interactive , -i		Keep STDIN open even if not attached;
# --init : Run an init inside the container that forwards signals and reaps processes;
