Tensorflow serving: "No assets to save/writes" when exporting models

Question

Recently I am trying to deploy deep learning services using tensorflow serving. But I got the following infos when exporting my model:

  INFO:tensorflow: No assets to save
  INFO:tensorflow: No assets to write
  INFO:tensorflow: SavedModel written to: b'./models/1/saved_model.pb'

I don't really understand what happening here. What does "No assets to save/write" mean? Is everthing goes well? btw，by running the official example Serving a tensorflow model, I got the same infos.

Assets mean any external files that are needed for you model. Common examples are vocabularies and embedding matrices. If your model does not have any external dependencies, these messages are expected. Note that they are logged at "INFO" level.
