Rasa vs dialoGPT

Hi guys, I am new for rasa. Can anyone explain the difference between rasa and dialoGPT. Which one is better to develop AI chatbot for non English language(limited dataset).

Thank you.

@Solamino Which language? and what are the instances of dataset? What type of Chatbot you want to develop?

I want to develop a tour and travel assistant bot. the dataset will be in the Amharic language ( non-English) and consist of conversation between the tourist and the tour guide guy. and i want to create my own tokenizer or normalizer based on the language.

@Solamino It will be a Voice OR Text?
