How to prevent the container from automatically exiting after running once？

I found that after I run and play a training session, the container automatically exits, and when restart is used, an exception will be thrown. failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "-e": executable file not found in $PATH: unknown 
Hope you can help me with this problem, thanks ! @smy20011
