## DialoGPT_AfriWOZ |
|
|
|
This is a fine-tuned model of DialoGPT (small) on the AfriWOZ dataset. It is intended to be used as a conversational system in Wolof language. |
|
The dataset it's trained on is limited in scope, as it covers only certain domains such as restaurants, hotel, taxi, and booking. |
|
|
|
The perplexity achieved on the test and validation sets are 20.74 and 11.66, respectively. |

### How to use |
|
|
|
Now we are ready to try out how the model works as a chatting partner! |
|
|
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
import torch |
|
tokenizer = AutoTokenizer.from_pretrained("tosin/dialogpt_afriwoz_wolof") |
|
model = AutoModelForCausalLM.from_pretrained("tosin/dialogpt_afriwoz_wolof") |
|
# 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) |
|
# pretty print last ouput tokens from bot |
|
print("DialoGPT_wolof_Bot: {}".format(tokenizer.decode(chat_history_ids[:, bot_input_ids.shape[-1]:][0], skip_special_tokens=True))) |
