Software
My most popular software packages are:
EPyT-Flow -- EPANET Python Toolkit - Flow 
EPyT-Flowis a Python package building on top of EPyT for providing easy access to water distribution network simulations. It aims to provide a high-level interface for the easy generation of hydraulic and water quality scenario data. However, it also provides access to low-level functions by EPANET and EPANET-MSX.
CEML -- Counterfactuals for Explaining Machine Learning models - A Python toolbox 
CEML is a Python toolbox for computing counterfactuals. Counterfactuals can be used to explain the predictions of machine learing models.
It supports many common machine learning frameworks:
- scikit-learn (1.3.1)
- PyTorch (2.0.1)
- Keras & Tensorflow (2.13.1)
Furthermore, CEML is easy to use and can be extended very easily. See the following user guide for more information on how to use and extend CEML.
