+// This header file defines EdgeTpuManager, and EdgeTpuContext.
+// EdgeTpuContext is an object associated with one or more tflite::Interpreter.
+// Instances of this class should be allocated through

+// More than one Interpreter instances can point to the same context. This means
+// the tasks from both would be executed under the same TPU context.
+// The lifetime of this context must be longer than all associated
+// tflite::Interpreter instances.
+//
+// Typical usage with NNAPI:
+//
+// std::unique_ptr<tflite::Interpreter> interpreter;
+// tflite::ops::builtin::BuiltinOpResolver resolver;
+// auto model =
+// tflite::FlatBufferModel::BuildFromFile(model_file_name.c_str());

+// // Registers edge TPU custom op handler with Tflite resolver.
+// resolver.AddCustom(edgetpu::kCustomOp, edgetpu::RegisterCustomOp());
+//
+// tflite::InterpreterBuilder(*model, resolver)(&interpreter);
+//
+// interpreter->AllocateTensors();
+// .... (Prepare input tensors)
+// interpreter->Invoke();
+// .... (retrieving the result from output tensors)
+//
+// // Releases interpreter instance to free up resources associated with
+// // this custom op.
+// interpreter.reset();
+//
+// Typical usage with Non-NNAPI:
+//
+// // Sets up the tpu_context.
+// auto tpu_context =
