PyTorch
PyTorch is an open-source machine learning framework that accelerates the path from research prototyping to production deployment. Its key features include production readiness, distributed training, a robust ecosystem, and cloud support. PyTorch offers flexible mode switching, scalable distributed training capabilities, and a rich ecosystem of tools and libraries. The framework is well-supported on major cloud platforms, facilitating development and scaling. PyTorch's strengths lie in its flexibility and ease of use, suitable for researchers and developers. However, users should note that mastering all of PyTorch's capabilities may require a learning curve despite its powerful features.
