什么是 PyTorch？

PyTorch is an open-source deep learning framework that enables fast, flexible experimentation and efficient production through a user-friendly front-end, distributed training, and an ecosystem of tools and libraries.

核心功能

  • Production Ready with TorchScript

    Provides ease-of-use and flexibility in eager mode while seamlessly transitioning to graph mode for speed, optimization, and functionality in C++ runtime environments.

  • TorchServe

    Easy-to-use tool for deploying PyTorch models at scale that is cloud and environment agnostic and supports multi-model serving, logging, metrics, and RESTful endpoints for application integration.

  • Distributed Training

    Native support for asynchronous execution of collective operations and peer-to-peer communication accessible from Python and C++ to optimize performance in research and production.

  • Mobile Support

    End-to-end workflow from Python to deployment on iOS and Android that extends the PyTorch API for common preprocessing and integration tasks needed for mobile applications (experimental).

  • Robust Ecosystem

    Rich ecosystem of tools and libraries built by researchers and developers that extends PyTorch and supports development in areas from computer vision to reinforcement learning.

  • Native ONNX Support

    Export models in the standard ONNX (Open Neural Network Exchange) format for direct access to ONNX-compatible platforms, runtimes, visualizers, and more.

  • Cloud Support

    Well supported on major cloud platforms, providing frictionless development and easy scaling.
