How to load and run offline docker image built using docker-compose build?

I'm new to docker and have been dabbling with it for the past few days. I've managed to successfully use docker-compose for a multi-container deployment involving an app server (flask + gunicorn) and web server (nginx).

Now, I'd like to recreate the deployment on an offline machine. After doing research, it seems that most have mentioned use docker save and docker load to transfer over the base images. However, I'm wondering whether its possible to recreate the deployment from the image created by docker-compose build? Reason being I would like to skip the entire process of wheeling my python package dependencies for offline use, which I would have to do for the method starting from the base images.

I've tried to save that particular image (output of docker-compose build) and load it on the offline machine, and then tried docker run and docker-compose up but both don't seem to work. Would like to check with the community whether this method is even possible, and if so what's the right way to go about it?

Thanks!

To solve my issue, I ended up making an image of each individual container post pip install, then using docker-compose.yml simply to spin them up. As David mentioned, it doesn't seem possible to spin up the container from the single image output by docker-compose build.
