Thanks for the PR! I have changed the base to the "new-apis" branch (instead of master), and some conflicts need to be resolved. can you take a look?

Waiting to hear from @NielsRogge about this PR. Also, is there any way to put unit tests for this?

[sarthakpati]

2 points from me:

1. Tests need to be added. See the entrypoint tests here.
2. I am guessing hf needs to be added as a dependency to setup.py.

@sarthakpati, Sure I'll start working on the tests. Also I'll add the dependencies in the next commit.

The mlcube-docker errors in actions are related to https://github.com/mlcommons/mlcube/issues/360

Changing the pip version in the workflow should help - please put this change in a separate PR, @pranayasinghcsmpl

Edit: done in #887

[sarthakpati]

@pranayasinghcsmpl - the latest changes from the base branch should make things easier. However, we are still missing updates to setup.py.
