Star History
Distributions
We've already included six distributions: four of them are based on lightweight Deepy socialbot, one is a full-sized Dream chatbot (based on Alexa Prize Challenge version) in English and a Dream chatbot in Russian.
Deepy Base
Base version of Lunar assistant. Deepy Base contains Spelling Preprocessing annotator, template-based Harvesters Maintenance Skill, and AIML-based open-domain Program-y Skill based on Dialog Flow Framework.
Deepy Advanced
Advanced version of Lunar assistant. Deepy Advanced contains Spelling Preprocessing, Sentence Segmentation, Entity Linking and Intent Catcher annotators, Harvesters Maintenance GoBot Skill for goal-oriented responses, and AIML-based open-domain Program-y Skill based on Dialog Flow Framework.
Deepy FAQ
FAQ version of Lunar assistant. Deepy FAQ contains Spelling Preprocessing annotator, template-based Frequently Asked Questions Skill, and AIML-based open-domain Program-y Skill based on Dialog Flow Framework.
Deepy GoBot
Goal-oriented version of Lunar assistant. Deepy GoBot Base contains Spelling Preprocessing annotator, Harvesters Maintenance GoBot Skill for goal-oriented responses, and AIML-based open-domain Program-y Skill based on Dialog Flow Framework.
Dream
Full version of DeepPavlov Dream Socialbot.
This is almost the same version of the DREAM socialbot as at
the end of Alexa Prize Challenge 4.
Some API services are replaced with trainable models.
Some services (e.g., News Annotator, Game Skill, Weather Skill) require private keys for underlying APIs,
most of them can be obtained for free.
If you want to use these services in local deployments, add your keys to the environmental variables (e.g., ./.env, ./.env_ru).
This version of Dream Socialbot consumes a lot of resources
because of its modular architecture and original goals (participation in Alexa Prize Challenge).
We provide a demo of Dream Socialbot on our website.
Dream Mini
Mini version of DeepPavlov Dream Socialbot. This is a generative-based socialbot that uses English DialoGPT model to generate most of the responses. It also contains intent catcher and responder components to cover special user requests. Link to the distribution.
Dream Russian
Russian version of DeepPavlov Dream Socialbot. This is a generative-based socialbot that uses Russian DialoGPT by DeepPavlov to generate most of the responses. It also contains intent catcher and responder components to cover special user requests. Link to the distribution.
Prompted Dream Distributions
Mini version of DeepPavlov Dream Socialbot with the use of prompt-based generative models.
This is a generative-based socialbot that uses large language models to generate most of the responses.
You can upload your own prompts (json files) to common/prompts,
add prompt names to PROMPTS_TO_CONSIDER (comma-separated),
and the provided information will be used in LLM-powered reply generation as a prompt.

Quick Start
System Requirements
- Operating System: Ubuntu 18.04+, Windows 10+ (через WSL & WSL2), MacOS Big Sur;
- Version of
dockerfrom 20 and above; - Version of
docker-composev1.29.2; - Operative Memory from 2 Gb (using proxy), from 4 Gb (LLM-based prompted distributions) and from 20 Gb (old scripted distributions).
Clone the repo
git clone https://github.com/deeppavlov/dream.git
Install docker and docker-compose
If you get a "Permission denied" error running docker-compose, make sure to configure your docker user correctly.
Run one of the Dream distributions
Deepy Base
docker-compose -f docker-compose.yml -f assistant_dists/deepy_base/docker-compose.override.yml up --build
Deepy Advanced
docker-compose -f docker-compose.yml -f assistant_dists/deepy_adv/docker-compose.override.yml up --build
Deepy FAQ
docker-compose -f docker-compose.yml -f assistant_dists/deepy_faq/docker-compose.override.yml up --build
Deepy GoBot
docker-compose -f docker-compose.yml -f assistant_dists/deepy_gobot_base/docker-compose.override.yml up --build
Dream (via proxy)
The easiest way to try out Dream is to deploy it via proxy. All the requests will be redirected to DeepPavlov API, so you don't have to use any local resources. See proxy usage for details.
docker-compose -f docker-compose.yml -f assistant_dists/dream/docker-compose.override.yml -f assistant_dists/dream/dev.yml -f assistant_dists/dream/proxy.yml up --build
Dream (locally)
Please note, that DeepPavlov Dream components require a lot of resources. Refer to the components section to see estimated requirements.
docker-compose -f docker-compose.yml -f assistant_dists/dream/docker-compose.override.yml -f assistant_dists/dream/dev.yml up --build
We've also included a config with GPU allocations for multi-GPU environments:
AGENT_PORT=4242 docker-compose -f docker-compose.yml -f assistant_dists/dream/docker-compose.override.yml -f assistant_dists/dream/dev.yml -f assistant_dists/dream/test.yml up
When you need to restart particular docker container without re-building (make sure mapping in assistant_dists/dream/dev.yml is correct):
AGENT_PORT=4242 docker-compose -f docker-compose.yml -f assistant_dists/dream/docker-compose.override.yml -f assistant_dists/dream/dev.yml restart container-name
Prompted Dream
docker-compose -f docker-compose.yml -f assistant_dists/dream_persona_prompted/docker-compose.override.yml -f assistant_dists/dream_persona_prompted/dev.yml -f assistant_dists/dream_persona_prompted/proxy.yml up --build
We've also included a config with GPU allocations for multi-GPU environments.
Let's chat
DeepPavlov Agent provides several options for interaction: a command line interface, an HTTP API, and a Telegram bot
CLI
In a separate terminal tab run:
docker-compose exec agent python -m deeppavlov_agent.run agent.channel=cmd agent.pipeline_config=assistant_dists/dream/pipeline_conf.json
Enter your username and have a chat with Dream!
HTTP API
Once you've started the bot, DeepPavlov's Agent API will run on http://localhost:4242.
You can learn about the API from the DeepPavlov Agent Docs.
A basic chat interface will be available at http://localhost:4242/chat.
Telegram Bot
Currently, Telegram bot is deployed instead of HTTP API.
Edit agent command definition inside docker-compose.override.yml config:
agent:
command: sh -c 'bin/wait && python -m deeppavlov_agent.run agent.channel=telegram agent.telegram_token=<TELEGRAM_BOT_TOKEN> agent.pipeline_config=assistant_dists/dream/pipeline_conf.json'
NOTE: treat your Telegram token as a secret and do not commit it to public repositories!
Configuration and proxy usage
Dream uses several docker-compose configuration files:
./docker-compose.yml is the core config which includes containers for DeepPavlov Agent and mongo database;
./assistant_dists/*/docker-compose.override.yml lists all components for the distribution;
./assistant_dists/dream/dev.yml includes volume bindings for easier Dream debugging;
./assistant_dists/dream/proxy.yml is a list of proxied containers.
If your deployment resources are limited, you can replace containers with their proxied copies hosted by DeepPavlov.
To do this, override those container definitions inside proxy.yml, e.g.:
convers-evaluator-annotator:
command: ["nginx", "-g", "daemon off;"]
build:
context: dp/proxy/
dockerfile: Dockerfile
environment:
- PROXY_PASS=proxy.deeppavlov.ai:8004
- SERVICE_PORT=8004
and include this config in your deployment command:
docker-compose -f docker-compose.yml -f assistant_dists/dream/docker-compose.override.yml -f assistant_dists/dream/dev.yml -f assistant_dists/dream/proxy.yml up --build
By default, proxy.yml contains all available proxy definitions.
