I am trying to use the rasa paraphrasing experimental feature but I got this error.

It’s due to some changes in HF transformer source code. If you go to the models.py file included in the notebook and change ALL_MODELS to:

ALL_MODELS = sum((conf for conf in (GPT2Config.get_config_dict("gpt2"), OpenAIGPTConfig.get_config_dict("openai-gpt"))), ())

  • for gpt2 you can use the following weights: “gpt2”, “gpt2-medium”, “gpt2-large”, “gpt2-xl”, “distilgpt2”

Thanks, this worked perfectly.

Hi, I am facing the same issue. Can you please share the path of this ‘models.py’ file? I am unable to locate it.
