Submit problem

Hi,
I use dockerfile to make my runtime environment.
when I follow this, Locally build docker image with dockerfile via aicrowd-repo2docker. Everything is fine.

But When I submit, something went wrong,
in debug-logs:
“python: can’t open file ‘client_launcher.py’: [Errno 2] No such file or directory”,
how to solve this problem?
thanks. :grinning:
