DialoGPT Trained on the Speech of a Game Character

This is an instance of microsoft/DialoGPT-medium trained on a game character, Joshua from The World Ends With You. The data comes from a Kaggle game script dataset.

Chat with the model:

from transformers import AutoTokenizer, AutoModelWithLMHead

  

tokenizer = AutoTokenizer.from_pretrained("r3dhummingbird/DialoGPT-medium-joshua")

model = AutoModelWithLMHead.from_pretrained("r3dhummingbird/DialoGPT-medium-joshua")

# Let's chat for 4 lines

for step in range(4):

    # encode the new user input, add the eos_token and return a tensor in Pytorch

    new_user_input_ids = tokenizer.encode(input(">> User:") + tokenizer.eos_token, return_tensors='pt')

    # print(new_user_input_ids)

    # append the new user input tokens to the chat history

    bot_input_ids = torch.cat([chat_history_ids, new_user_input_ids], dim=-1) if step > 0 else new_user_input_ids

    # generated a response while limiting the total chat history to 1000 tokens, 

    chat_history_ids = model.generate(

        bot_input_ids, max_length=200,

        pad_token_id=tokenizer.eos_token_id,  

        no_repeat_ngram_size=3,       

        do_sample=True, 

        top_k=100, 

        top_p=0.7,

        temperature=0.8

    )

    

    # pretty print last ouput tokens from bot

    print("Master YODA: {}".format(tokenizer.decode(chat_history_ids[:, bot_input_ids.shape[-1]:][0], skip_special_tokens=True)))
