def METHOD_NAME(self, requests):
    """`execute` must be implemented in every Python model. `execute`
    function receives a list of pb_utils.InferenceRequest as the only
    argument. This function is called when an inference is requested
    for this model. Depending on the batching configuration (e.g. Dynamic
    Batching) used, `requests` may contain multiple requests. Every
    Python model, must create one pb_utils.InferenceResponse for every
    pb_utils.InferenceRequest in `requests`. If there is an error, you can
    set the error argument when creating a pb_utils.InferenceResponse.
    Parameters
    ----------
    requests : list
      A list of pb_utils.InferenceRequest
    Returns
    -------
    list
      A list of pb_utils.InferenceResponse. The length of this list must
      be the same as `requests`
