  * Performs classification on a GMLImage input, returns an array of
  * categorization results where each member in the array is an array of
  * TFLClass objects for each classification head.
  + * This method currently supports inference on only following type of images:
  + * 1. RGB and RGBA images for GMLImageSourceTypeImage.
  + * 2. kCVPixelFormatType_32RGBA, kCVPixelFormatType_32BGRA, kCVPixelFormatType_24RGB
  + * for GMLImageSourceTypePixelBuffer and GMLImageSourceTypeSampleBuffer. If
  + * you are using AVCaptureSession to setup camera and get the frames for inference,
  + * you must request for one of these supported formats from AVCaptureVideoDataOutput.
  + * For a sample code snippet, please refer to:
  + * https://github.com/tensorflow/examples/blob/master/lite/examples/image_classification/ios/ImageClassification/Camera%20Feed/CameraFeedManager.swift#L253

  * @param image input to the model.
  * @return An NSArray<NSArray<TFLClass *>*> * of classification results.
