paccmann_gp

Bayesian Optimisation with Gaussian Processes for molecular generative models.

Installation

Create a conda environment:

conda env create -f conda.yml

Activate the environment:

conda activate paccmann_gp

Example usage

In the examples directory is an example script example.py that makes use of paccmann_gp for a combined optimisation for QED, SAscore and affinity to the transcription factor ERG.

(paccmann_gp) $ python examples/example.py -h
usage: example.py [-h]
                    svae_path affinity_path
                    optimisation_name


positional arguments:
  svae_path          Path to downloaded SVAE model.
  affinity_path      Path to the downloaded affinity prediction model.
  optimisation_name  Name for the optimisation.

The trained SVAE and affinity models can be downloaded from the SELFIESVAE and affinity folders located here.
