GPT2 trained on MultiWOZ.2.1

This repository provides all the necessary tools to perform response generation from an end-to-end system within SpeechBrain. For a better experience, we encourage you to learn more about SpeechBrain. The performance of the model is the following:

Release	Test PPL	Test BLEU 4	GPUs
15.08.23	4.01	2.54e-04	1xV100 32GB

Credits

The model is provided by vitas.ai.

Pipeline description

This dialouge system is composed of 2 different but linked blocks:

Pretrained GPT Tokenizer that transforms words into subwords.
GPT2LMHeadModel to generate the next sentence given the history of the dialogue.

The system is trained with dialogue from MultiWOZ corpus.

Install SpeechBrain

First of all, please install SpeechBrain with the following command:

pip install speechbrain==1.0.2

Please notice that we encourage you to read our tutorials and learn more about SpeechBrain.

Generating your Own Dialuge

python

from speechbrain.inference.text import GPTResponseGenerator
res_gen_model = GPTResponseGenerator.from_hparams(source="speechbrain/MultiWOZ-GPT-Response_Generation", savedir="pretrained_models/MultiWOZ-GPT-Response_Generation", pymodule_file="custom.py")
print("Hi,How could I help you today?", end="\n")
while True:
  turn = input()
  response = res_gen_model.generate_response(turn)
  print(response, end="\n")

Inference on GPU

To perform inference on the GPU, add run_opts={"device":"cuda"} when calling the from_hparams method.

Parallel Inference on a Batch

Please, see this Colab notebook to figure out how to transcribe in parallel a batch of input sentences using a pre-trained model.

Training

The model was trained with SpeechBrain (986a2175). To train it from scratch follows these steps:

Clone SpeechBrain:

bash

git clone https://github.com/speechbrain/speechbrain/
git checkout d9fb58f5693311ae2715dae3208e0fafaaf04a81

Install it:

cd speechbrain
pip install -r requirements.txt
pip install -e .

Run Training:

cd recipes/MultiWOZ/response_generation/gpt/
pip install -r extra_requirements.txt
python train_with_gpt.py hparams/train_gpt.yaml --data_folder=your_data_folder

You can find our training results (models, logs, etc) here
