torch pytorch

Torch is a scientific computing framework that provides a wide range of functionalities for machine learning and deep learning. PyTorch is a Python-based machine learning library that is built on top of Torch. PyTorch provides more flexibility than Torch and is widely used in research and industry for developing deep learning models. PyTorch is known for its dynamic computational graph, which allows for easy debugging and efficient memory usage. It also provides a simple and intuitive interface for building neural networks and can be used for a variety of tasks including computer vision, natural language processing, and reinforcement learning.
