# A State-of-the-Art Large-scale Pretrained Response Generation Model (DialoGPT)
## This project page is no longer maintained as DialoGPT is superseded by [GODEL](https://github.com/microsoft/GODEL), which outperforms DialoGPT according to the results of [this paper](https://arxiv.org/pdf/2206.11309.pdf). Unless you use DialoGPT for reproducibility reasons, we highly recommend you switch to [GODEL](https://github.com/microsoft/GODEL).
This repository contains the source code and trained model for a large-scale pretrained dialogue response generation model. The [human evaluation results](#human_eval) indicate that the response generated from DialoGPT is comparable to human response quality under a single-turn conversation Turing test.
The repository is based on [huggingface pytorch-transformer](https://github.com/huggingface/transfer-learning-conv-ai) and [OpenAI GPT-2](https://github.com/openai/gpt-2), containing data extraction script, model training code and pretrained small (117M) medium (345M) and large (762M) model checkpoint.
The model is trained on 147M multi-turn dialogue from Reddit discussion thread. The largest model can be trained in several hours on a 8 V100 machines (however this is not required), with distributed training and FP16 option.
The include script can be used to reproduce the results of DSTC-7 grounded dialogue generation challenge and a 6k multi-reference dataset created from Reddit data.

## Recommended Configuration
- Linux Ubuntu 16.04
- GPU with at least 12G memory
DialoGPT was developed entirely on **Ubuntu 16.04**, and -- depending on our availability -- we try to provide support if you experience difficulties running the code on the same configuration. However, we are **unable to provide support for other distributions or operating systems**. Portions of the code may run on other UNIX flavors (macOS, Windows subsystem for Linux, Cygwin, etc.), but it is recommended to use Ubuntu for the main training code.
The training code can be run on CPU, but it can be slow. We would recommend to use GPU to train and finetune all models. There is no minimal limit of the number of GPUs. However, if using distributed train for multiple GPUs configuration, the speed-up vs the number of GPUs is roughly sub-linear. To simulate the same batchsize when using less GPUs, please use a larger `gradient_accumulation_steps` in model training.
The 117M and 345M model can be loaded in a single GPU with 12G memory. The 762M model would require a single GPU that has greater than 16G memory for efficient training. The training speed on a benchmark data with 50M training instances and V100 GPUs:
| n\_gpu | epoch time (h) | token/sec |
|----------------------|--------|--------|
| 1 | 118 | 10847 |
| 2 | 62 | 20645 |
| 4 | 34 | 37647 |
| 8 | 18 | 71356 |
Fine-tuning from our pretrained model on a new dataset typically requires 1-2 epochs.
## Setup & Installation (TL;DR)
We created a demo script `demo.py` to ease the difficulty of the deployment of this system. The `demo.py` contains a pipeline of **model downloading**, data extraction, data preprocessing and model training over a dummy dataset within one commandline.
#### Train model with Conda Environment
Please use the below commandlines to clone, install the requirements and load the Conda environment (Note that the Nvidia CUDA 10.0 developer toolkit is required):
```bash
sudo apt-get install -y make wget gzip bzip2 xz-utils zstd sed
```
```bash
git clone https://github.com/microsoft/DialoGPT.git
cd DialoGPT
conda env create -f LSP-linux.yml -n LSP
conda activate LSP
```
If you run this on an architecture other than Linux, please use `LSP-generic.yml` instead of `LSP-linux.yml` but please note that the generic one is not tested in all platform, so the stablity can not be gauranteed.
To use fp16 training, please install apex by using commands below
```bash
conda activate LSP
git clone https://github.com/NVIDIA/apex
cd apex
git reset --hard 3d01e4a0a188cc8df54bc6e44cf5eb40ff6b4cc5
pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" .
python3.6 demo.py
```
#### Train model with Docker environment
To start, first install the docker and Nvidia-docker from their official repos.
The image environment for running the code can be loaded as below:
*Nvidia-docker v2.**
```bash
$ docker run --gpus all --ipc=host --rm -it -v $PWD:/workspace --network=host icaruszyz/large-scale-training:dialogpt bash
```
*Nvidia-docker v1.**
```bash
$ nvidia-docker --rm -it -v $PWD:/workspace --network=host icaruszyz/large-scale-training:dialogpt bash
```
Inside the docker container, run
```bash
python demo.py
```
## Pipeline details
This section explains all components in the `demo.py`.
#### Data loading
Before running `demo.py`, you can set *DATA_FOLDER* (default value `./models`) in `demo.py` as the place you want to download all the data and pretrained/fine-tuned models. Then simply run
```bash
python demo.py
```
to
* automatically download models and data,
* prepare raw data into db that is ready to use for the program,
* generate a training scripts.
Note that by default the `demo.py` will use a dummy data, please specify the Reddit training data by using option `--data`. Three options are available:`dummy`,`small` and `full`.
```bash
python demo.py --data small
python demo.py --data full
```
The small Reddit data is around 140MB and the full Reddit data is more than 27GB. You can prepare a cup of coffee when processing with the full Reddit data because **it takes a long time**!
To generate the 6k multi-ref test set data, pleaser run `demo.py` and set the data option to 'full', the generation will be located at
`./data/test.refs.txt`
#### Pretrained model
The pretrained and fine-tuned models are available on azure blobstorage.
Please run/see `demo.py` for more details about how to download/use those models. Or you could download directly by using the links in `demo_utils.py`.
#### Preparing data
First, use the `prepare4db.sh` to convert a tsv data file into the correct format that the following script can recognize.
The trainig data need to be then processed into a database file with below commandline:
```bash
python prepro.py --corpus $DATA_PATH
```
#### Using the training script
The training script can be used in single GPU or multiple GPU settings (distributed training across multiple GPUs within a single node):
```bash
python ./LSP_train.py # Single GPU training
python -m torch.distributed.launch --nproc_per_node=8 ./LSP_train.py # Training on 8 GPUs
```
The training script accept several arguments to tweak the training:
Argument | Type | Default value | Description
---------|------|---------------|------------
max\_seq\_length | `int` | `128` | Maximum number of tokens for each training instance.
train\_input\_file | `str` | `""` | Path of the training dataset in a .db format
eval\_input\_file | `str` | `""` | Path of the validation set in a tsv format
continue_from | `int` | `0` | Resuming the training after a specified number of steps
fp16 | `boolean` | `True` | Whether to use 16-bits floating point for model training.
train\_batch\_size | `int` | `4` | Batch size for training
valid\_batch\_size | `int` | `4` | Batch size for validation
gradient\_accumulation\_steps | `int` | `2` | Accumulate gradients on several steps
learning\_rate | `float` | `1e-5` | Learning rate
lr\_schedule | `str` | `noam` | Learning rate schedule can be chosen from [`noam`, `noamwd`, `BERT`, `None`]
num\_optim\_steps | `int` | `1000000` | Number of training optimization steps
no_token_id | `boolean` | `True` | If set True, using all-zeros token-type embedding.
During the training, two log files will be updated. The `train_log.txt` and `eval_log.txt` contains the model loss, perplexity and training speed (tokens/sec) statistics for the training and dev set.
The log file and saved model checkpoint can be found in `./models/output_model`
#### Model decoding
We note that even with properly filtered Reddit dataset, sometimes our model can still generate moderately toxic/inappropriate responses. Due to this reason, we are unable to provide the decoding script at this time (The live demo and decoding script access is upon invitation only now ).
We are currently still working on a controlled decoding method to prevent this system from toxic generation. Please stay tuned.
**See issues [#3](https://github.com/microsoft/DialoGPT/issues/3) and [Reddit discussions](https://www.reddit.com/r/MachineLearning/comments/dt5woy/p_dialogpt_state_of_the_art_conversational_model/) for some discussions on third-party decoding methods.**

## Models
We release 6 fine-tuned models which can be further fine-tuned on low-resource user-customized dataset. The total parameters in these models range from 117M to 762M, in accord with OpenAI GPT-2 model sizes.
| Model | Fine-tuned from GPT-2| Trained from scratch
|----------------------|--------|--------|
| DialoGPT 762M model| [\[link\]](https://acvrpublicycchen.blob.core.windows.net/dialogpt/multiref/large_ft.pkl) [\[huggingface model card\]](https://huggingface.co/microsoft/DialoGPT-large) | [\[link\]](https://acvrpublicycchen.blob.core.windows.net/dialogpt/multiref/large_fs.pkl) |
| DialoGPT 345M model| [\[link\]](https://acvrpublicycchen.blob.core.windows.net/dialogpt/multiref/medium_ft.pkl) [\[huggingface model card\]](https://huggingface.co/microsoft/DialoGPT-medium) | [\[link\]](https://acvrpublicycchen.blob.core.windows.net/dialogpt/multiref/medium_fs.pkl) |
| DialoGPT 117M model| [\[link\]](https://acvrpublicycchen.blob.core.windows.net/dialogpt/multiref/small_ft.pkl) [\[huggingface model card\]](https://huggingface.co/microsoft/DialoGPT-small)| [\[link\]](https://acvrpublicycchen.blob.core.windows.net/dialogpt/multiref/small_fs.pkl) |
| DialoGPT 345M model (reverse, for MMI)| [link](https://acvrpublicycchen.blob.core.windows.net/dialogpt/multiref/small_reverse.pkl) | -|
| [DialogRPT](https://github.com/golsun/DialogRPT) (**new** ranking models) | [link](https://github.com/golsun/DialogRPT) | -|
The model files can be loaded exactly as the GPT-2 model checkpoints from Huggingface's [Transformers](https://github.com/huggingface/transformers). You can find the corresponding configuration files (`merges.txt`, `config.json`, `vocab.json`) in DialoGPT's repo in `./configs/*`.
The reverse model is predicting the source from the target. This model is used for MMI reranking.
The [DialogRPT](https://github.com/golsun/DialogRPT) models our recently proposed ranking models used to predict the human feedback (upvotes, replies) of the responses. These models can be used to improve the DialoGPT generation quality (see our [EMNLP paper](https://arxiv.org/abs/2009.06978) for details).
## Retraining full models
### Data Preparation
The first step to retrain the full models is to generate the aforementioned 27GB Reddit dataset. This involves downloading full Reddit submission and comments dumps from [https://files.pushshift.io/reddit](https://files.pushshift.io/reddit) and creating intermediate files, which overall require **700GB of local disk space**. Downloading and processing the full data requires about 1-2 days, depending on your (CPU) compute capabilties (e.g., ~24 hours with 8 cores on a recent computer). Assuming you ran the above setup and installation steps (conda activate LSP, etc.), you can create the full dataset by running either:
```
python demo.py --data full
```
or
```
cd reddit_extractor; SIZE=full make -j 8; cd ..
```
The former command calls the latter, so the two methods are equivalent. We recommend the former, as the latter is mostly useful if you run into any problem or want to customize any arguments (e.g., the `make` command lets you build only a subset of the data). Note that the downloading phase can be error prone, for example based on your geolocation (firewall, etc.). If the above commands fail to generate `data/train.tsv`, or if that file is not anywhere close to 27GB, it means something went wrong. In that case, you may want to inspect `reddit_extractor/wget-log` and `reddit_extractor/logs/*.log` for any obvious error (e.g., wget unable to download from pushshift.io). If error messages don't make sense to you, feel free to contact us. If so, please be sure to include any error messages gathered from these log files.
Training data statistics: the generated training tsv file should be roughly 26.8 GB uncompressed, with 146.8M training instances, 3.87B source tokens, and 2.14B target tokens (including utterance-level 0/1 weights). The resulting train.tsv file should contain 146,846,215 lines.
### Training
We recommand generating the above data using the `demo.py --data full`, as it (1) generates the data, (2) converts it into DB format, and (3) trains a model using `python LSP_train.py`. Please directly edit `demo.py` if you want to customize any of the hyperparameters.
## Evaluations
#### DSTC-7 challenge
Our model achieved the state-of-the-art results in [DSTC-7 Challenge response generation task](https://github.com/mgalley/DSTC7-End-to-End-Conversation-Modeling).
| Experiment | NIST2 | NIST4 | BLEU2 | BLEU4 | METEOR | ENT-4 | DIST-1 | DIST-2 | Avg. Len |
|--------------------|-------|-------|--------|-------|--------|----------|------------|------------|---------|
| Human response | 2.62 | 2.65 | 12.35% | 3.13% | 8.31% | 10.45 | 16.66% | 67.01% | 18.8 |
| DSTC-7 Winner | 2.51 | 2.52 | 14.35% | 1.83% | 8.07% | 9.03 | 10.89% | 32.49% | 15.1 |
| DialoGPT 345M | 2.80 | 2.82 | 14.16% | 2.31% | 8.51% | **10.08** | 9.13% | 39.73% | 16.9 |

where ENT represents the [Entropy score](https://arxiv.org/abs/1809.05972), and DIST represents the [Distinct score](https://arxiv.org/pdf/1510.03055.pdf). For all metrics except the average length, larger are better.
Note that the superior automatic evaluation comparing to human responses does not necessary imply that our model achieves human parity. Please check out our paper for more detailed analysis.
To fine-tune the `345M` DialoGPT model on the DSTC-7 challenge data on a server with 8 V100 GPUs, please run the following commandline (The DSTC data can be found at [DSTC-7 repo](https://github.com/mgalley/DSTC7-End-to-End-Conversation-Modeling)):
```bash
python3 -m torch.distributed.launch --nproc_per_node=8 train_LSP.py --init_checkpoint ./models/medium/medium_ft.pkl --train_input_file ./data/DSTC_train.db --eval_input_file ./data/DSTC_valid.tsv --model_name_or_path ./model/medium/ --learning_rate 1e-4 --train_batch_size 64 --eval_batch_size 64 --no_token_id
```
The trained model can be found at [DSTC medium model](https://acvrpublicycchen.blob.core.windows.net/dialogpt/DSTC/medium_ft.pkl)
#### Evaluation

## 6K multi-ref dataset result
### Automatic evaluation
We test on 6K multi-ref dataset from Reddit. The results are summarized in below
| Experiment | NIST2 | NIST4 | BLEU2 | BLEU4 | METEOR | ENT-4 | DIST-1 | DIST-2 | Avg. Len |
|--------------------|-------|-------|--------|-------|--------|----------|------------|------------|---------|
| Human response | 3.41 | 4.25 | 17.90% | 7.48% | 10.64% | 11 | 14.50% | 63.00% | 13.1 |
| DialoGPT 117M | 2.39 | 2.41 | 10.54% | 1.55% | 7.53% | 10.78 | 8.60% | 39.90% | 12.8 |
| DialoGPT 345M | 3 | 3.06 | 16.96% | 4.56% | 9.81% | 9.13 | 6.80% | 26.30% | 12.2 |
| DialoGPT 762M | 2.84 | 2.9 | 18.66% | 5.25% | 9.66% | 9.72 | 7.76% | 29.93% | 11.2 |
| DialoGPT 345M (BS) | **3.4** | **3.5** | **21.76%** | **7.92%** | 10.74% | 10.48 | **12.38%** | **48.74%** | 11.3 |
| DialoGPT 345M (w/MMI)| 3.28 | 3.33 | 15.68% | 3.94% | **11.23%** | **11.25** | 9.39% | 45.55% | 17.2 |
We further conduct human evaluations (6K examples for each methods, each example is evaluated by 3 human judges). The results show a strong evidence that our generation quality is towards approaching the quality of real human responses, under this non-interactive Turing test:
*Relevance*: A and B, which one is more relevant to the source prompt.

## Disclaimer
This repository aims to facilitate research in large-scale pretraining for conversational data. This toolkit contains only part of the modeling machinery needed to actually produce a model weight file in a running dialog. On its own, this model provides only information about the weights of various text spans; in order for a researcher to actually use it, they will need to bring conversational data of their own and decode the response generation from the pretrained system. Microsoft is not responsible for any generation from the 3rd party utilization of the pretrained system.
