PyTorch is an open source, machine learning framework used for both research prototyping and production deployment. According to its source code repository, PyTorch provides two high-level features:
- Tensor computation (like NumPy) with strong GPU acceleration.
- Deep neural networks built on a tape-based autograd system.
Originally developed at Idiap Research Institute, NYU, NEC Laboratories America, Facebook, and Deepmind Technologies, with input from the Torch and Caffe2 projects, PyTorch now has a thriving open source community. PyTorch 1.10, released in October 2021, has commits from 426 contributors, and the repository currently has 54,000 stars.
