        public OrtSymbolBlock​(ai.onnxruntime.OrtSession session,
                      OrtNDManager manager)
        Constructs a OrtSymbolBlock.

        You can create a PtSymbolBlock using Model.load(java.nio.file.Path, String).

        Parameters:
        session - the OrtSession contains the model information
        manager - the NDManager to holds the NDArray
