PyTorch is a production-ready Python machine-learning library with excellent examples, applications and use cases supported by a strong community. This library absorbs strong GPU acceleration and enables you to apply it from applications like NLP. As it supports GPU and CPU computations, it provides you with performance optimization and scalable distributed training in research as well as production. Deep neural networks and Tensor computation with GPU acceleration are the two high-end features of the PyTorch. It includes a machine learning compiler called Glow that boosts the performance of deep learning frameworks.
