          Pushing your models to the Hugging Face Hub ([hf.co](https://hf.co/))
          allows you to share your models with others. On top of that, you can try
          the models directly in the browser with the available widgets.
  
          Before running this command, login to Hugging Face with `huggingface-cli login`.
  
          You can specify either a `serialization_dir` or an `archive_path`, but using the
          first option is recommended since the `serialization_dir` contains more useful
          information such as metrics and TensorBoard traces.
