A Streamlit app to monitor de novo molecule generation 'live' or analyse results post-hoc is also provided (see Figure ). This is useful to gain quick insights into generative model behaviour with respect to chemistry generated, without needing to wait until the end of optimisation (especially in the case of computationally expensive scoring functions). This is run automatically during optimisation if specified in the configuration file, alternatively, it can be run manually at any time via the streamlit run molscore/gui/monitor.py command.
