This code gives the tensorflow implementation of PaccMann as of our paper in Molecular Pharmaceutics.
paccmann is a package for drug sensitivity prediction and is the core component of the repo.
The package provides a toolbox of learning models for IC50 prediction using drug's chemical properties and tissue-specific cell lines gene expression.

}We strongly recommend to work inside a virtual environment (venv).
Create the environment:
python3 -m venv venvActivate it:
source venv/bin/activateThe module can be installed either in editable mode:
pip3 install -e .Or as a normal package:
pip3 install .Models can be trained using the script bin/training_paccmann that is installed together with the module. Check the examples for a quick start.
For more details see the help of the training command by typing training_paccmann -h:
