torch.compiler.PrecompileError

exception torch.compiler.PrecompileError

The error type raised by torch.compiler.precompile and its artifacts.

Raised when capture, lowering, load, or a runtime call violates the precompile contract – e.g. a tensor baked as a constant (invariant 1), an unsupported / effectful op, a non-tensor output the inductor backend cannot lower, or a runtime input whose shape or memory format differs from the example (invariants 3 and 6). See Note [precompile programming model] in this module for the full contract.
