# HomerBot: A conversational chatbot imitating Homer Simpson
|
||||
|
||||
This model is a fine-tuned [DialoGPT](https://huggingface.co/microsoft/DialoGPT-medium) (medium version) on Simpsons [scripts](https://www.kaggle.com/datasets/pierremegret/dialogue-lines-of-the-simpsons).
|
||||
|
||||
More specifically, we fine-tune DialoGPT-medium for 3 epochs on 10K **(character utterance, Homer's response)** pairs
|
||||
|
||||
For more details, check out our git [repo](https://github.com/jesseDingley/HomerBot) containing all the code.

|
||||
### How to use
|
||||
|
||||
|
||||
```python
|
||||
from transformers import AutoModelForCausalLM, AutoTokenizer
|
||||
import torch
|
||||
|
||||
tokenizer = AutoTokenizer.from_pretrained("DingleyMaillotUrgell/homer-bot")
|
||||
model = AutoModelForCausalLM.from_pretrained("DingleyMaillotUrgell/homer-bot")
|
||||
|
||||
# Let's chat for 5 lines
|
||||
for step in range(5):
|
||||
# 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')
|
||||
|
||||
# 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=1000,
|
||||
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
|
||||
)
|
||||
|
||||
# print last outpput tokens from bot
|
||||
print("Homer: {}".format(tokenizer.decode(chat_history_ids[:, bot_input_ids.shape[-1]:][0], skip_special_tokens=True)))
|
||||
```
