TorchDynamo
The entry-layer component of the PyTorch 2.0 compilation stack. It intercepts Python bytecode to convert dynamic graph code into an optimizable intermediate representation, preserving Python's flexibility while providing the foundation for subsequent compiler optimizations.
Timeline (last 90 days)
torch.compile is a just-in-time compilation (JIT) mechanism introduced in PyTorch 2.0, and its workflow has three steps: TorchDynamo captures the computation graph at the bytecode level, AOTAutograd handles the forward and backward graph structures, and finally it is handed to the backend compiler to generate executable code.
torch.compile relies on the TorchDynamo bytecode interception mechanism and the TorchInductor code generation backend.
Compared to TorchScript, TorchDynamo does not require developers to manually annotate or rewrite model code, and offers better compatibility with dynamic control flow.
The PyTorch 2.x series improves model inference performance through compilation technologies such as TorchScript and TorchDynamo.
