PyTorch An open source machine learning framework for research and production.

What is PyTorch?

PyTorch is an open-source machine learning framework widely used for applications such as computer vision and natural language processing. It provides a seamless transition from research prototyping to production deployment. The framework supports dynamic computation graphs, enabling flexibility during the model development phase. It also offers robust tools like TorchScript for switching between eager execution and graph modes, facilitating optimization for production environments.

PyTorch emphasizes scalability with its `torch.distributed` backend, enabling efficient distributed training across multiple GPUs and machines. It integrates well with major cloud providers like AWS, Google Cloud, and Azure, offering easy scaling and deployment options. The framework is backed by a strong community and a rich ecosystem of libraries and tools, further extending its capabilities for various machine learning tasks. It requires Python 3.9 or later for the latest versions.
