当尝试使用TensorFlow的toco转换器将* .pb模型转换为* .tflite（用于在Android上运行）时，我得到以下内容
2018-05-11 20:38:10.841641: I tensorflow/cc/saved_model/loader.cc:242] Loading SavedModel with tags: { serve }; from: /home/user_name/Downloads/model_directory

To inspect available tag-sets in the SavedModel, please use the SavedModel CLI: `saved_model_cli`Failed to load exported model from /home/user_name/Downloads/model_directory. **Ensure the model contains the required tags 'serve'.**
知道怎么解决吗？
