Description

For models that are fetched from docker, they have their information file being copied from the container storage to the host machine, this might lead to some incorrect data schema as the file being copied is a representation of the model environment inside the container and not the one on the host machine.

Changes to be made

Added a modify_information method to docker functionality, to modify the content of what is being copied from docker container.

Status

The information file now reflects the correct service class and size for model's fetched from DockerHub.

information.json

To do

Include model source value to model information file copied from container storage.
