pgmpy is a Python package for causal inference and probabilistic inference using Directed Acyclic Graphs (DAGs) and Bayesian Networks with a focus on modularity and extensibility. Implementations of various algorithms for Causal Discovery (a.k.a, Structure Learning), Parameter Estimation, Approximate (Sampling Based) and Exact inference, and Causal Inference are available.
