ModelDB is an exceptional open-source system designed to help data scientists manage their machine learning (ML) model lifecycle effectively. Whether you’re looking to version models, track metadata, or manage experiments, ModelDB has you covered. This blog will walk you through the steps needed to get up and running with ModelDB in a user-friendly manner.

Understanding ModelDB: The Key Features

Before diving into the installation, let’s understand what ModelDB offers:

• Reproducibility of ML models
• Management of ML experiments with performance dashboards
• Tracking models throughout their lifecycle, from development to deployment
• Integration with Docker and Kubernetes
• Clients available in Python and Scala
• Beautiful dashboards for model performance visualization
• Flexible metadata logging capabilities
• Compatibility with frameworks like TensorFlow and PyTorch

Up and Running in Just 5 Minutes

Follow these straightforward steps to get ModelDB up and running quickly:

1. Install Docker (and Docker Compose).
2. Setup ModelDB via Docker Compose:
   

   bash docker-compose -f docker-compose-all.yaml up

   Note: The modeldb-backend service requires a backend/config/config.yaml file to run. You can either clone the repo before running the docker-compose command or create the file manually.

3. Install the ModelDB pip package (it’s included in the verta package):
   

   bash pip install verta

4. Start versioning a model or logging workflow. You can also run any of the detailed examples found in the repository:
   

   python
   from verta import Client
   
   client = Client(http="http://localhost:3000")
   proj = client.set_project("My first ModelDB project")
   expt = client.set_experiment("Default Experiment")
   
   # Log the first run
   run = client.set_experiment_run("First Run")
   run.log_hyperparameters({"regularization": 0.5})
   # ... your model training code goes here
   run.log_metric("accuracy", 0.72)
   
   # Log the second run
   run = client.set_experiment_run("Second Run")
   run.log_hyperparameters({"regularization": 0.8})
   # ... your model training code goes here
   run.log_metric("accuracy", 0.83)
   

   That’s it! Navigate to http://localhost:3000 to find the ModelDB Web UI and check out the models you just logged.

A Simple Analogy

Think of ModelDB as a library for machine learning models. Just like a library categorizes books and keeps track of who borrowed which book, ModelDB organizes ML models and tracks all their versions, performances, and metadata. Instead of worrying about losing your models or confused about their progress, ModelDB helps you keep everything in one tidy bookshelf, making your research and development process smooth and efficient.

Troubleshooting Tips

If you encounter issues during your installation or usage, consider the following troubleshooting ideas:

• Ensure Docker is installed and running correctly.
• Check if the config.yaml file is created and correctly referenced.
• Verify that ports are correctly mapped and not blocked by firewall settings.
• For issues specific to Docker or environment setups, check the Deployment documentation.
