Darma Chat development is moved to https://github.com/isi-nlp/isi_darma/tree/main/darma_chat
ParlAI (pronounced “par-lay”) is a python framework for sharing, training and testing dialogue models, from open-domain chitchat, to task-oriented dialogue, to visual question answering.
Its goal is to provide researchers:
- 100+ popular datasets available all in one place, with the same API, among them PersonaChat, DailyDialog, Wizard of Wikipedia, Empathetic Dialogues, SQuAD, MS MARCO, QuAC, HotpotQA, QACNN & QADailyMail, CBT, BookTest, bAbI Dialogue tasks, Ubuntu Dialogue, OpenSubtitles, Image Chat, VQA, VisDial and CLEVR. See the complete list here.
- a wide set of reference models -- from retrieval baselines to Transformers.
- a large zoo of pretrained models ready to use off-the-shelf
- seamless integration of Amazon Mechanical Turk for data collection and human evaluation
- integration with Facebook Messenger to connect agents with humans in a chat interface
- a large range of helpers to create your own agents and train on several tasks with multitasking
- multimodality, some tasks use text and images
ParlAI is described in the following paper: “ParlAI: A Dialog Research Software Platform", arXiv:1705.06476 or see these more up-to-date slides.
Follow us on Twitter and check out our Release notes to see the latest information about new features & updates, and the website http://parl.ai for further docs. For an archived list of updates, check out NEWS.md.
For those who want to start with ParlAI now, you can try our Colab Tutorial.
ParlAI currently requires Python3.8+ and Pytorch 1.6 or higher.
Dependencies of the core modules are listed in requirements.txt. Some
models included (in parlai/agents) have additional requirements.
We strongly recommend you install ParlAI in a venv or conda environment.
We do not support Windows at this time, but many users report success on Windows using Python 3.8 and issues with Python 3.9. We are happy to accept patches that improve Windows support.
Standard Installation
If you want to use ParlAI without modifications, you can install it with:
pip install parlaiDevelopment Installation
Many users will want to modify some parts of ParlAI. To set up a development environment, run the following commands to clone the repository and install ParlAI:
git clone https://github.com/facebookresearch/ParlAI.git ~/ParlAI
cd ~/ParlAI; python setup.py developAll needed data will be downloaded to ~/ParlAI/data. If you need to clear out
the space used by these files, you can safely delete these directories and any
files needed will be downloaded again.

A large set of scripts can be found in parlai/scripts. Here are a few of them.
Note: If any of these examples fail, check the installation section to see if you have missed something.

parlai display_data -t squadEvaluate an IR baseline model on the validation set of the Personachat task:
parlai eval_model -m ir_baseline -t personachat -dt validTrain a single layer transformer on PersonaChat (requires pytorch and torchtext). Detail: embedding size 300, 4 attention heads, 2 epochs using batchsize 64, word vectors are initialized with fasttext and the other elements of the batch are used as negative during training.

- core: contains the primary code for the framework
- agents: contains agents which can interact with the different tasks (e.g. machine learning models)
- scripts: contains a number of useful scripts, like training, evaluating, interactive chatting, ...
- tasks: contains code for the different tasks available from within ParlAI
- mturk: contains code for setting up Mechanical Turk, as well as sample MTurk tasks
- messenger: contains code for interfacing with Facebook Messenger
- utils: contains a wide number of frequently used utility methods
- crowdsourcing: contains code for running crowdsourcing tasks, such as on Amazon Mechanical Turk
- chat_service: contains code for interfacing with services such as Facebook Messenger
- zoo: contains code to directly download and use pretrained models from our model zoo
