Docker Push Keeps Failing

I have created local model docker image and try to sumbit following the submission guidelines. But it just keeps failing in `docker push` step during the transmission, especially a component that is 8.44G in total that always stops at about 2GB. I do change the tag everytime, and my university network connection is stable enough. I was wondering if such large size of docker image is expected, if this problem is shared by any other teams, and what could be the potential solution other than keep trying pushing. Thanks!
