Cause (Documented platform behavior): The TorchScript exporter caps opset at ONNX_TORCHSCRIPT_EXPORTER_MAX_OPSET; newer opsets are only handled by the dynamo exporter. Fix status: documented_behavior Other error fragments: - To use a newer opset version, consider 'torch.onnx.export(..., dynamo=True)'.
