PyTorch is an open source machine learning framework that facilitates the transition from research prototyping to production deployment. It offers features like TorchScript, which allows for seamless switching between eager and graph modes, and TorchServe for accelerated production deployment. With its distributed training capabilities and a robust ecosystem of tools and libraries for computer vision and NLP, PyTorch supports scalable development in various domains. It is well supported on major cloud platforms, providing easy scaling and frictionless development. Additional features include the availability of pre-trained models, support for mobile platforms, and integration with other tools and frameworks. PyTorch is used by companies and universities to reduce inference costs, drive scale, push the state of the art in NLP, and efficiently research new algorithmic approaches. The PyTorch community offers resources, documentation, tutorials, and developer support to contribute, learn, and solve real-world machine learning problems.
