Difference between docker image from dockerhub and build from Dockerfile

1

Hi all,

It seems that the pyTorch docker image from dockerhub has size 3.11GB and the CUDA files (cuda.h, etc) are not inside /usr/local/, but when I build from the Dockerfile provided in repo it has size around 5 GB with all the CUDA files in expected directories. What kind of sorcery is this?
