Not able to run predictions for new drugs

[GemaRG96]

Hi! I've succeed on running the model, but I would like to predict sensitivity for new drugs. The cell lines I'm using are already in the data set you used but the drugs are not. I've managed to get the drug features, etc. but I don't now how to proceed with other files, for example, the similarity matrix. Could you assist me on how to get the model running predictions for new drugs?

Thanks

P.S.: I only want to run prediction, not to retrain the model nor fine-tune
