Distributed DAG framework for machine learning with UI

MLComp

MLComp is a distributed DAG (Directed acyclic graph) framework for machine learning with UI.

The goal of MLComp is to provide tools for training, inferencing, creating complex pipelines (especially for computer vision) in a rapid, well manageable way.

MLComp is compatible with: Python 3.6+, Unix operation system.

Features

  • Amazing UI
  • Catalyst support
  • Distributed training
  • Supervisor that controls computational resources
  • Synchronization of both code and data
  • Resource monitoring
  • Full functionality of the pause and continue on UI
  • Auto control of the requirements
  • Code dumping (with syntax highlight on UI)
  • Kaggle integration
  • Hierarchical logging
  • Grid search
  • Experiments comparison
  • Customizing layouts

Installation

  1. Install MLComp package

    pip install mlcomp
    mlcomp init
    
  2. Setup your environment. Please consider Environment variables section

  3. Run db, redis, mlcomp-server, mlcomp-workers:

    Variant 1: minimal (if you have 1 computer)

    Run all necessary (mlcomp-server, mlcomp-workers, redis-server), it uses SQLITE:

    mlcomp-server start
    

    Variant 2: full

    a. Change your Environment variables to use PostgreSql

    b. Install rsync on each work computer

    sudo apt-get install rsync
    

    Ensure that every computer is available by SSH protocol with IP/PORT you specified
    in the Environment variables file.

    rsync will perform the following commands:

    to upload

    rsync -vhru -e "ssh -p {target.port} -o StrictHostKeyChecking=no" \
    {folder}/ {target.user}@{target.ip}:{folder}/ --perms  --chmod=777
    

    to download

    rsync -vhru -e "ssh -p {source.port} -o StrictHostKeyChecking=no" \
    {source.user}@{source.ip}:{folder}/ {folder}/ --perms  --chmod=777
    

    c. Install apex for distributed learning

    d. To Run postgresql, redis-server, mlcomp-server, execute on your server-computer:

    cd ~/mlcomp/configs/
    docker-compose -f server-compose.yml up -d
    

    e. Run on each worker-computer:

    mlcomp-worker start
    

UI

Web site is available at http://{WEB_HOST}:{WEB_PORT}

By default, it is http://localhost:4201

The front is built with AngularJS.

In case you desire to change it, please consider front's Readme page

Usage

Run

mlcomp dag PATH_TO_CONFIG.yml

This command copies files of the directory to the database.

Then, the server schedules the DAG considering free resources.

For more information, please consider Docs

Docs and examples

API documentation and an overview of the library can be
found here Docs

You can find advanced tutorials and MLComp best practices in the examples folder of the repository.

Environment variables

The single file to setup your computer environment is located at ~/mlcomp/configs/.env

  • ROOT_FOLDER - folder to save MLComp files: configs, db, tasks, etc.
  • TOKEN - site security token. Please change it to any string
  • DB_TYPE. Either SQLITE or POSTGRESQL
  • POSTGRES_DB. PostgreSql db name
  • POSTGRES_USER. PostgreSql user
  • POSTGRES_PASSWORD. PostgreSql password
  • POSTGRES_HOST. PostgreSql host
  • PGDATA. PostgreSql db files location
  • REDIS_HOST. Redis host
  • REDIS_PORT. Redis port
  • REDIS_PASSWORD. Redis password
  • WEB_HOST. MLComp site host. 0.0.0.0 means it is available from everywhere
  • WEB_PORT. MLComp site port
  • CONSOLE_LOG_LEVEL. log level for output to the console
  • DB_LOG_LEVEL. log level for output to the database
  • IP. Ip of a work computer. The work computer must be accessible from other work computers by these IP/PORT
  • PORT. Port of a work computer. The work computer must be accessible from other work computers by these IP/PORT (SSH protocol)
  • MASTER_PORT_RANGE. distributed port range for a work computer. 29500-29510 means that if
    this work computer is a master in a distributed learning, it will use the first free port
    from this range. Ranges of different work computers must not overlap.
  • NCCL_SOCKET_IFNAME. NCCL network interface.
    You can see your network interfaces with ifconfig command.
