Is it possible to export a syntaxnet model (Parsey McParseface) to serve with TensorFlow Serving?
<p>I have the demo.sh working fine and I've looked at the parser_eval.py and grokked it all to some extent.  However, I don't see how to serve this model using TensorFlow Serving. There are two issues I can see off the top:</p>

<p>1) There's no exported model for these graphs, the graph is built at each invocation using a graph builder (e.g. structured_graph_builder.py), a context protocol buffer, and a whole bunch of other stuff that I don't understand fully at this point (it seems to register additional syntaxnet.ops as well). So... is it possible, and how would I export these models into the "bundle" form required by Serving and the <code>SessionBundleFactory</code>? If not, it seems the graph building logic / steps will need to be re-implemented in C++ because the Serving only runs in C++ context.</p>

<p>2) demo.sh is actually two models literally piped together with UNIX pipe, so any Servable would have to (problably) build two sessions and marshal the data from one to the other. Is this a correct approach? Or is it possible to build a "big" graph containing both models "patched" together and export that instead?</p>
