PyTorch is an open-source machine learning library for Python.

Pytorch was developed by Facebook's AI Research group

PyTorch is based on the popular Torch library, which is written in the programming language Lua

PyTorch provides a number of tools and libraries for building and training deep learning models, including CNN, RNN and LSTM networks.

PyTorch supports both CPU and GPU computations, allowing users to take advantage of the power of modern GPU for faster training.

PyTorch includes a dynamic computational graph, which allows users to change the structure of the graph on the fly

PyTorch integrates well with other popular Python libraries, such as NumPy and scikit-learn.
