convlab 3.0.0.dev20221130

An Open-source Dialog System Toolkit

ConvLab-3

ConvLab-3 is a flexible dialog system platform based on a unified data format for task-oriented dialog (TOD) datasets. The unified format serves as the adapter between TOD datasets and models: datasets are first transformed to the unified format and then loaded by models. In this way, the cost of adapting $M$ models to $N$ datasets is reduced from $M\times N$ to $M+N$. While retaining all features of ConvLab-2, ConvLab-3 greatly enlarges supported datasets and models thanks to the unified format, and enhances the utility of reinforcement learning (RL) toolkit for dialog policy module. For typical usage, see our paper. Datasets and Trained models are also available on Hugging Face Hub.

Updates

• 2022.11.30: ConvLab-3 release.

Installation

You can install ConvLab-3 in one of the following ways according to your need. Higher versions of torch and transformers may also work.

Git clone and pip install in development mode (Recommend)

For the latest and most configurable version, we recommend installing ConvLab-3 in development mode.

Clone the newest repository:

git clone --depth 1 https://github.com/ConvLab/ConvLab-3.git

Install ConvLab-3 via pip:

cd ConvLab-3
pip install -e .

Pip install from PyPI

To use ConvLab-3 as an off-the-shelf tool, you can install via:

pip install convlab

Note that the data directory will not be included due to the package size limitation.

Using Docker

We also provide Dockerfile for building docker. Basically it uses the requirement.txt and then installs ConvLab-3 in development mode.

# create image
docker build -t convlab .

# run container
docker run -dit convlab

# open bash in container
docker exec -it CONTAINER_ID bash

Unified datasets are available under data/unified_datasets directory as well as Hugging Face Hub. We will continue adding more datasets listed in this issue. If you want to add a listed/custom dataset to ConvLab-3, you can create an issue for discussion and then create pull-request. We will list you as the contributors and highly appreciate your contributions!

Models

We list newly integrated models in ConvLab-3 that support unified data format and obtain strong performance. You can follow the link for more details about these models. Other models can be used in the same way as in ConvLab-2.

Task	Models	Input	Output
Response Generation	T5	Context	Response
Goal-to-Dialogue	T5	Goal	Dialog
Natural Language Understanding	T5, BERTNLU, MILU	Context	DA-U
Dialog State Tracking	T5, SUMBT, SetSUMBT, TripPy	Context	State
RL Policy	DDPT, PPO, PG	State, DA-U, DB	DA-S
Natural Language Generation	T5, SC-GPT	DA-S	Response
End-to-End	SOLOIST	Context, DB	State, Response
User simulator	TUS, GenTUS	Goal, DA-S	DA-U, (Response)

Trained models are available on Hugging Face Hub.

Contributing

We welcome contributions from community. Please see issues to find what we need.

• If you want to add a new dataset, model, or other feature, please describe the dataset/model/feature in an issue before creating pull-request.
• Small change like fixing a bug can be directly made by a pull-request.
