class_docstr: Your Python model must use the same class name. Every Python model
  that is created must have "TritonPythonModel" as the class name.
docstr: `finalize` is called only once when the model is being unloaded.
  Implementing `finalize` function is optional. This function allows
  the model to perform any necessary clean ups before exit.
