MLEM helps you package and deploy machine learning models. It saves ML models in a standard format that can be used in a variety of production scenarios such as real-time REST serving or batch processing.

• Run your ML models anywhere: Wrap models as a Python package or Docker Image, or deploy them to Heroku, SageMaker or Kubernetes (more platforms coming soon). Switch between platforms transparently, with a single command.

• Model metadata into YAML automatically: Automatically include Python requirements and input data needs into a human-readable, deployment-ready format. Use the same metafile on any ML framework.

• Stick to your training workflow: MLEM doesn't ask you to rewrite model training code. Add just two lines around your Python code: one to import the library and one to save the model.

• Developer-first experience: Use the CLI when you feel like DevOps, or the API if you feel like a developer.

The main reason to use MLEM instead of other tools is to adopt a GitOps approach to manage model lifecycles.

• Git as a single source of truth: MLEM writes model metadata to a plain text file that can be versioned in Git along with code. This enables GitFlow and other software engineering best practices.

• Unify model and software deployment: Release models using the same processes used for software updates (branching, pull requests, etc.).

• Reuse existing Git infrastructure: Use familiar hosting like Github or Gitlab for model management, instead of having separate services.

• UNIX philosophy: MLEM is a modular tool that solves one problem very well. It integrates well into a larger toolset from Iterative.ai, such as DVC and CML.

This a quick walkthrough showcasing deployment functionality of MLEM.

Please read Get Started guide for a full version.

MLEM requires Python 3.

To install the pre-release version:

Check out what we have:

If you want to follow this Quick Start, you'll need to sign up on https://heroku.com, create an API_KEY and populate HEROKU_API_KEY env var (or run heroku login in command line). Besides, you'll need to run heroku container:login. This will log you in to Heroku container registry.

Now we can deploy the model with mlem deploy (you need to use different app_name, since it's going to be published on https://herokuapp.com):
