Mariadb Datafile Error?

[Tiaonmmn]

When I just use docker-compose -f single.yml up,the db1 container reports the following error:

So,the pymysql reports erros also:pymysql.err.InternalError: Packet sequence number wrong - got 1 expected 0 Maybe the mysql data file is coruptted?

Have a try to restart the docker service, and try again? I have not meat this problem before.
