1   Features

Could archiving, storing, managing and organizing machine learning models be done efficiently and with great focus on user experience? Sure, Maisie does just that.

Maisie is a friendly, easy to use assistant that consists of:

• Web Application written in React
• Backend API written in Python, Flask
• Client Application/Package written in Python and hosted on PyPI

It integrates seamlessly with your favorite tools and provides you with all the important data, such as:

• Git revisions for all trained models, as well as information about source branches
• Searchable, filterable hyperparameters, parameters and metrics
• A single identifying dataset name, as well as an optional description
• Permanent URLs for easy sharing and downloading of stored models

2   Installing

You can get the most current package from PyPI

$ pip install Maisie

Using it in your training environment is fairly straightforward:

import maisie
from sklearn.externals import joblib

# Define your model here

model.fit(X, y)
model_filename = "example_model.pkl"
joblib.dump(model, model_filename)

# Define your metrics, fetch parameters and hyperparameters

models = maisie.Models()
models.upload(
    name="My first uploaded model",
    filename=model_filename,
    dataset_name="Singly Identifying Dataset Name",
    metrics={"accuracy": accuracy},
    hyperparameters=hyperparameters,
    parameters=parameters,
)

3   Deploying

3.1   Using docker-compose

This repository provides a pre-configured docker-compose.yml file that contains sensible default options.

Before starting the containers, you should create a local .env file using the included .env.sample.

To start up all services, run:

$ docker-compose up

To stop your services, you can press Ctrl+C/Ctrl+D. If you started the services in the background using docker-compose up -d, the correct way to do this would be:

$ docker-compose stop

3.2   Fetching individual images

Both frontend and backend images are automatically published to Docker Hub as soon as new stable release is made available.

Links

• Frontend image on Docker Hub
• Backend image on Docker Hub
• ...other services

For reference, you can look at the sample Ansible playbook that deploys all containers to a specified host using the locally configured .env file.

4   Contributing

4.1   Getting started

1. Clone the repository from the develop branch

$ git clone -b develop git@github.com:nokia-wroclaw/innovativeproject-ml-models-management.git

2. Install pre-commit
3. Inside the project's root directory install all required githooks:

$ pre-commit install

4. To start all required services for local development, run:

$ docker-compose up

5. You're all set up!

4.2   Fixing existing issues

1. Pick one of the open issues or create a new one
2. Create a new branch named issue-[number]-[short description] derived from the develop branch, for example

$ git checkout -b issue-42-project-removal-permissions develop

3. Make sure your implementation fixes the actual problem and is well tested.

4.3   Implementing new features

When implementing new features, you should start by creating a new branch named feature-[short description] derived from the develop branch, for example

$ git checkout -b feature-new-user-profile develop

4.4   Commiting the changes

To run all tests and check whether all required pre-commit githooks are satisfied, run

$ pre-commit run --all-files

Your commit message should briefly summarize the changes (if possible) in plain English. To learn how to write a proper commit message, check out this article.

When ready, create a new pull request compared with the develop branch set as a base branch.

5   Documentation

For the lastest stable release, the documentation can be seen at docs.maisie.dev.
