Scout.ml: Dead simple CI/CD for ML teams.

Scout.ml is a tool to track, version, and deploy machine learning experiments from within your Git workflow.

There are 3 components:

  1. CLI tool: sct
  2. Web app: https://app.scout.ml:16043
  3. GitHub app: [Link here]

0. Setup

  1. Edit user_config.yaml in .scout/ directory.
  2. Run sct init in the root directory of the ML project.

Example config file:

# /Users/gilfoyle/chatbot/.scout/user_config.yaml:

version: 1

scout:
  job_id_ref: "EVAL_JOB_ID"
  root_dir: "/Users/gilfoyle/chatbot"
  remote:
    platform: "gcloud" # gcloud, aws
    url: "gs://piedpiper"
    executable_path: "/Users/gilfoyle/google-cloud-sdk/bin/gcloud"
  bucket_id: "gs://piedpiper"

app:
  username: "gilfoyle"
  password: "gilfoyle123"

job_id_ref: variable of evaluation job ID in .sh or .py script
remote: set up connection with cloud ML platform (gcloud, aws)
url: URL of cloud storage bucket
executable_path: absolute path of cloud ML platform CLI executable
app: credentials for web app login

1. CLI Tool

Every time an experiment is run, Scout automatically tracks/versions models, datasets, and code.

Core CLI commands:

  1. sct run [FILE]. File can be either .sh or .py and should contain training and evaluation code. Usage: sct run train_and_evaluate.py.
  2. git push-sct. Git hook to automatically associate Git commit hashes with experiment data. Using this will push code normally to GitHub/GitLab and update Scout data.

2. Web app: https://app.scout.ml:16043

Full log of all ML experiments and results run with sct run. Experiments linked with Git commits from running git push-sct will be flagged for review/deployment.

3. GitHub app: [Link here]

After pushing to GitHub with git push-sct, opening a pull request will trigger the Scout.ml bot to auto-comment with experiment results + metadata. Roadmap: Scout.ml will automatically detect model regressions + flag dataset changes. GitHub app will prevent merge/raise error within PR console.

Notes

  1. Scout CLI uses cronjobs to monitor job progress + metrics. You'll need to give Terminal this permission when prompted the first time.
