Describe the bug

Previous attempts #223 & #249 have not resulted in expected behaviour.

How To Reproduce

First, install a model from scivision catalog, where model_repo is the link to. the pip installable GitHub repo.

load_pretrained_model(model_repo)

Then, modify the code in the model_repo, push changes to GitHub and reinstall in scivision:

load_pretrained_model(model_repo, allow_install="force")

Expected behaviour

Changes made to the model code should be present when the model is used after reinstallation.

Currently, you have to manually do pip uninstall model_package_name and then re-run load_pretrained_model for changes to be picked up.
