test: enable trace_autograd_ops for torch 2.11 compile/export#283
Merged
Conversation
torch 2.11 no longer honors torch._dynamo.allow_in_graph for torch.autograd.grad; tracing it under torch.compile/export now requires torch._dynamo.config.trace_autograd_ops=True, otherwise Dynamo raises torch._dynamo.exc.Unsupported. The segmented_polynomial tests call torch.autograd.grad inside compiled/exported modules and fail on 2.11. Set the flag session-wide in the torch tests' conftest (guarded with hasattr so older torch is unaffected). Signed-off-by: Jonathan Mitchell <jomitchell@nvidia.com>
