PyTorch

Deep learning framework for research and production

Why PyTorch?

PyTorch is my preferred deep learning framework for its intuitive API, dynamic computation graphs, and seamless path from research to production.

Key Features

Dynamic Computation Graphs

PyTorch's define-by-run approach offers:

  • Intuitive debugging with Python debuggers
