**CRSLab** is an open-source toolkit for building Conversational Recommender System (CRS). It is developed based on
Python and PyTorch. CRSLab has the following highlights:
- **Comprehensive benchmark models and datasets**: We have integrated commonly-used 6 datasets and 18 models, including graph neural network and pre-training models such as R-GCN, BERT and GPT-2. We have preprocessed these datasets to support these models, and release for downloading.
- **Extensive and standard evaluation protocols**: We support a series of widely-adopted evaluation protocols for testing and comparing different CRS.
- **General and extensible structure**: We design a general and extensible structure to unify various conversational recommendation datasets and models, in which we integrate various built-in interfaces and functions for quickly development.
- **Easy to get started**: We provide simple yet flexible configuration for new researchers to quickly start in our library.
- **Human-machine interaction interfaces**: We provide flexible human-machine interaction interfaces for researchers to conduct qualitative analysis.

## Installation
CRSLab works with the following operating systems：
- Linux
- Windows 10
- macOS X
CRSLab requires Python version 3.7 or later.
CRSLab requires torch version 1.8. If you want to use CRSLab with GPU, please ensure that CUDA or CUDAToolkit version is 10.2 or later. Please use the combinations shown in this [Link](https://pytorch-geometric.com/whl/) to ensure the normal operation of PyTorch Geometric.
### Install PyTorch
Use PyTorch [Locally Installation](https://pytorch.org/get-started/locally/) or [Previous Versions Installation](https://pytorch.org/get-started/previous-versions/) commands to install PyTorch. For example, on Linux and Windows 10:
```bash
# CUDA 10.2
conda install pytorch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 cudatoolkit=10.2 -c pytorch
# CUDA 11.1
conda install pytorch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 cudatoolkit=11.1 -c pytorch -c conda-forge
# CPU Only
conda install pytorch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 cpuonly -c pytorch
```
If you want to use CRSLab with GPU, make sure the following command prints `True` after installation:
```bash
$ python -c "import torch; print(torch.cuda.is_available())"
>>> True
```
### Install PyTorch Geometric
Ensure that at least PyTorch 1.8.0 is installed:
```bash
$ python -c "import torch; print(torch.__version__)"
>>> 1.8.0
```
Find the CUDA version PyTorch was installed with:
```bash
$ python -c "import torch; print(torch.version.cuda)"
>>> 11.1
```
For Linux:
Install the relevant packages:
```
conda install pyg -c pyg
```
For others：
Check PyG [installation documents](https://pytorch-geometric.readthedocs.io/en/latest/install/installation.html) to install the relevant packages.
### Install CRSLab
You can install from pip:
```bash
pip install crslab
```
OR install from source:
```bash
git clone https://github.com/RUCAIBox/CRSLab && cd CRSLab
pip install -e .
```
## Quick-Start
With the source code, you can use the provided script for initial usage of our library with cpu by default:
```bash
python run_crslab.py --config config/crs/kgsf/redial.yaml
```
The system will complete the data preprocessing, and training, validation, testing of each model in turn. Finally it will get the evaluation results of specified models.
If you want to save pre-processed datasets and training results of models, you can use the following command:
```bash
python run_crslab.py --config config/crs/kgsf/redial.yaml --save_data --save_system
```
In summary, there are following arguments in `run_crslab.py`:
- `--config` or `-c`: relative path for configuration file(yaml).
- `--gpu` or `-g`: specify GPU id(s) to use, we now support multiple GPUs. Defaults to CPU(-1).
- `--save_data` or `-sd`: save pre-processed dataset.
- `--restore_data` or `-rd`: restore pre-processed dataset from file.
- `--save_system` or `-ss`: save trained system.
- `--restore_system` or `-rs`: restore trained system from file.
- `--debug` or `-d`: use validation dataset to debug your system.
- `--interact` or `-i`: interact with your system instead of training.
- `--tensorboard` or `-tb`: enable tensorboard to monitor train performance.
## Models
In CRSLab, we unify the task description of conversational recommendation into three sub-tasks, namely recommendation (recommend user-preferred items), conversation (generate proper responses) and policy (select proper interactive action). The recommendation and conversation sub-tasks are the core of a CRS and have been studied in most of works. The policy sub-task is needed by recent works, by which the CRS can interact with users through purposeful strategy.
As the first release version, we have implemented 18 models in the four categories of CRS model, Recommendation model, Conversation model and Policy model.

Among them, the four CRS models integrate the recommendation model and the conversation model to improve each other, while others only specify an individual task.
For Recommendation model and Conversation model, we have respectively implemented the following commonly-used automatic evaluation metrics:
| Category | Metrics |
| :--------------------: | :----------------------------------------------------------: |
| Recommendation Metrics | Hit@{1, 10, 50}, MRR@{1, 10, 50}, NDCG@{1, 10, 50} |
| Conversation Metrics | PPL, BLEU-{1, 2, 3, 4}, Embedding Average/Extreme/Greedy, Distinct-{1, 2, 3, 4} |
| Policy Metrics | Accuracy, Hit@{1,3,5} |
## Datasets
We have collected and preprocessed 6 commonly-used human-annotated datasets, and each dataset was matched with proper KGs as shown below:
| Dataset | Dialogs | Utterances | Domains | Task Definition | Entity KG | Word KG |

## Performance
We have trained and test the integrated models on the TG-Redial dataset, which is split into training, validation and test sets using a ratio of 8:1:1. For each conversation, we start from the first utterance, and generate reply utterances or recommendations in turn by our model. We perform the evaluation on the three sub-tasks.
