What is a computation graph in PyTorch?

Updated May 17, 2026

Short answer

A computation graph represents operations for automatic differentiation.

Deep explanation

PyTorch dynamically builds graph during forward pass for backpropagation.

Real-world example

Used internally in all neural network training.

Common mistakes

  • Assuming static graphs like TensorFlow 1.x.

Follow-up questions
