# PyTorch

PyTorch is an open-source framework for machine learning and deep learning, used especially in research and the development of AI models. It offers a flexible and dynamic programming environment that makes it possible to build, train, and evaluate complex neural networks efficiently. PyTorch supports both CPUs and GPUs, which makes it attractive for a wide range of AI applications.

## Who is PyTorch suitable for?

PyTorch is aimed at researchers, developers, and data scientists who want to build powerful and customizable deep learning models. It is ideal for users who value flexibility in modeling and need rapid prototyping. It is also very popular in academic research because of its intuitive syntax and strong community. Beginners in AI benefit from extensive tutorials and an active user base that makes it easier to get started.
