PyMC is an open-source probabilistic programming library in Python, designed for Bayesian statistical modeling and inference. Built on top of Aesara, PyMC allows users to construct complex models using intuitive syntax and powerful backends for scalable and efficient computation. PyMC is ideal for research, machine learning, and data science applications that require uncertainty quantification and complex hierarchical modeling.

Features of PyMC:

• Intuitive model specification using standard Python syntax.
• Support for advanced inference methods like NUTS (No-U-Turn Sampler), HMC, and variational inference.
• Flexible modeling of complex hierarchical Bayesian models.
• Integration with popular scientific Python libraries such as NumPy, pandas, and ArviZ.
• Supports GPU acceleration and symbolic differentiation via Aesara.
• Actively developed with a vibrant open-source community and extensive documentation.
• Open-source and licensed under the Apache License 2.0.
• Ideal for use in research, epidemiology, social science, finance, and engineering domains.
