jcsun-00/HDN-DDI ? reverse-engineered prompt

Build me a clean way to run this HDN DDI project end to end so I can reproduce the reported drug interaction results without fighting the setup.

I want to be able to drop in the DrugBank and Twosides datasets in the right place, run the experiments multiple times, and then see the average performance in the notebook. Please make sure the scripts for the DrugBank and Twosides tests work smoothly, and if anything is missing or unclear, add a simple README style note inside the project so I know what to put where and what to run first.

If you need to check current docs or versions to make the environment work, go ahead and look them up. The goal is just to make this easy to run from a fresh setup and get the same kind of results the paper talks about.
