   Have you try the nlp model? I use latest code, dynamic sahpe don't working.
   recursively find the input to the control flow nodes , have some problems with fixed dynamic
input.
   
   For example, I set the 'Placeholder' op(the original shape is dynamic (-1,-1)) shape as
(1,30) in the from_tensorflow interface.First, for each control flow node, we backtrack all
its ancestor nodes until input nodes.But all the nodes we first backtracked do not necessarily
contain 'Placeholder' node, then the shape of these nodes is dynamic.until some control node
search for and get the 'Placeholder' node.
