转换代码如下：
tflite_convert --graph_def_file=/home/sir/project/models/faster/frozen_inference_graph.pb --output_file=/home/sir/project/models/faster/foo.tflite --input_arrays=image_tensor --output_arrays=detection_boxes,detection_classes --input_shape=1,299,299,3
这时会报错：Converting unsupported operation，具体报错很多。这里做个记录，证明无法将faster RCNN模型成功转化为tflite版本，从而移植到终端设备上。
