I haven't used onnx before but have worked with torchscript. With torchscript I have had to change the models quite a bit with to make it scriptable. If onnx requires similar amount of effort I don't think it will be useful.

I don't want to go through the hassle of scripting because we might change the model architectures soon. I need a quick and possibly inefficient (space wise, not perf wise) way to package the models without exposing source code.
