Root Cause

TorchScript compilation failed due to unsupported Python features.

generic

Workarounds

  1. 88% success Annotate types in forward(): use Tensor, int, float, bool
  2. 90% success Avoid dynamic Python features: comprehensions, **kwargs, generators

Dead Ends

Common approaches that don't work:

  1. Use torch.jit.trace instead 72% fail

    Only captures one execution path

  2. Remove TorchScript entirely 68% fail

    Loses deployment optimization
