  Converting composite operations from TensorFlow to fused operations in
  TensorFlow Lite is a hard problem. This is because:
  -1. Composite operations are represented in the TensorFlow graph as an
  - unstructured set of primitive operations. It can be very challenging to
  - identify (e.g. via pattern matching) the sub-graph corresponding to such a
  - composite operation.
  +1. Composite operations are represented in the TensorFlow graph as a set of

  1. There may be more than one TensorFlow implementation targeting a fused
  TensorFlow Lite operation. For example, there are many LSTM implementations
