PyTorch

PyTorch provides an open-source framework for tensor computation and deep learning, with a Python interface used to build and train neural networks. Its dynamic computation approach allows model behavior to follow ordinary program execution, making it practical to change operations at runtime and inspect intermediate results. Automatic differentiation calculates gradients for training, while CUDA support enables computation on compatible NVIDIA GPUs. Researchers can use this flexibility to experiment with model structures, and development teams can use the framework as part of production machine learning systems.

Related libraries and projects support computer vision, natural language processing and reinforcement learning workflows. PyTorch suits people who need control over model behavior and are comfortable working in Python. GPU acceleration depends on suitable hardware and software, and the framework still requires careful choices about data, training and deployment.
