I'm intrigued by pyTorch but I am really having a hard time groking what you mean by the whole "but that really doesn't extend well to any dynamic graph structure such as recursive tree structure creation. Since the computation graph has a different shape and size for every input they are difficult to batch and any pre-defined static graph is likely excessive, wasting computation, or inexpressive."

Would you mind providing a concrete example to relate to if you dont mind? Again, intrigued by PT so want to learn more about it vs TF...
