class_docstr: Test the process of importing the models from Hugging Face Transformers
  
  Test methods in this test suite check the following things
  1. Models loaded with Hugging Face Transformers cane be imported.
  2. The same model can be recreated without Hugging Face Transformers.

      # starts to fail. Therefore, we defer importing "transformers" until
      # the actual tests are started.
