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，我得到以下信息
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
2018-05-11 20:38:10.847390: I tensorflow/cc/saved_model/loader.cc:291] SavedModel load for tags { serve }; Status: fail. Took 6042 microseconds.
2018-05-11 20:38:10.848098: F tensorflow/contrib/lite/toco/toco_saved_model.cc:50] **Non-OK-status:** tensorflow::LoadSavedModel(tensorflow::SessionOptions(), tensorflow::RunOptions(), model_path, tags, bundle) **status: Not found:** Could not find meta graph def matching supplied tags: { serve }. 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'.**
知道如何解决吗？
